Morrow Project Overland Train

an Overland Train with three payload cars,

marked with Science branch symbol during Science team driver training


Concept and Development


     Built by the LeTourneau company (which also built the MARS-One and Scientific-One vehicles), the Overland Train consists of up to 22 electrically-powered modules -- at least one control car, plus payload cars and equipment cars. If the train is to be more than 5 cars long, or if lots of reversing is expected, another control car is usually attached at the rear; at least one control car should be present for every 10 payload or equipment cars.

     All of the Overland Train wheels use the same tires:  120" x 48" x 60", inflated at 12 psi; the bare tire itself weighs 1090 kilograms, and a complete tire-and-wheel has a mass of 1500 kilograms. There are pictures of complete wheel-and-tire sets being carried on the roof of payload cars.

     Here's a video of an Overland Train in motion.


An Overland Train during training in the 1970s. At the far end are a fuel tank car and two "power cars" (see text).


     These vehicles were not fitted with armament, and they were operated semi-publicly during testing and training, with "regular" power cars at the rear end to make noise and smoke. Here's another video!


The Army's version. Note again the fuel car and two power cars at the rear end.


note the fuel car and the two power cars at the end of this "non-Project" Overland Train.

This photo, taken from the cab of a Control Car, shows (from the foreground) the air conditioning and cooling system on the roof,

the ceiling hatch from the crew quarters, and the small crane used for changing tires. On either side of the crane are powerful spotlights.


Power Car


     The original (non-Morrow Project) Overland Train produced most of its electrical power in "power cars", which each had two gas turbine-generators; the control car had one much smaller power-generating gas turbine (only sufficient to move itself and one payload car); a tank car was also included, to carry most of the jet fuel. Power cars had a one-person cab, for a single driver to use when reversing the train. The Morrow Project doesn't use power cars, except in training; there is an accessory "driver's cab" which can be fitted onto a flatcar, if the train doesn't have a control car at each end. The gas turbines had significant problems with dust ingestion causing blade erosion.

the dark square isn't a window -- it's the turbine exhaust


      One reason for the power cars being at the rear of the Overland Train was a tentative concept by the Army (circa 1960) of having a nuclear (fission) reactor power supply!


Jungle Destroyer


      The Morrow Project purchased two of these as driver training vehicles, and for heavy load carrying -- though also because the manufacturer had them "lying around" -- SAC had tested them in the late 1950s for clearing crashed bombers from runways in a hurry. The same width as the Overland Train (5.25 meters), these are 17.5 meters long and 5 meters tall (over the blade-lifting arm) -- 3.4 meters from the ground to the cargo deck. Weighing 50 tons unloaded, they can carry 95 tons of cargo. Similarly to the Control Car of the Overland Train, the four rear wheels are not steered; all shock-absorbing is from the low pressure tires.

      When purchased by the Project, these were powered by a 600 HP Cummins diesel, driving an electrical generator; the Project removed the diesel engine and generator, and installed a fusion reactor. The Project also fitted them at the rear with the connections to lead (forwards) or follow (backwards) Overland Train vehicles -- though they do not have the array of radios, cameras, etc. that the Control Car of a proper Overland Train carries.

     The cargo deck has eleven fitting points for HIAB cranes, or for Mk 2 Mod 1 mortar/gun mounts -- four along each side, and three along the center line.


     The size of these vehicles made long-distance transport difficult -- they were at various training camps between the Sierra Nevada Mountains and the Rocky Mountains for almost the entire period between when they were acquired and the Atomic War.




     While the ground pressure on the high-flotation tires is low, and the power and torque available are high, the Overland Train cannot traverse every kind of terrain equally. In testing, the control car was unable to climb a 35 degree slope in a dry wash bank, and cannot climb sand dunes with slip faces 3 meters high or more. It leaves ruts about 1" deep in loose gravel, where a standard Army jeep leaves ruts 2" to 6" deep.

     The suspension will most likely keep any vertical acceleration to 0.2 G or less, on any terrain the vehicle can actually cross successfully.

     Cars are connected by a coupler bar, which can be used to pull "dead" cars; it also carries electrical power, braking control signals, status and emergency signals; and crew communications. A coupler bar weighs about 80 kilograms. Note that except for the rear four wheels on the Control Car, all wheels on the Overland Train are steered.

     The dynamic brake system uses the wheel hub motors running as generators to send electricity back into the system. There are two "dumps" for electrical power from the dynamic braking system:


  • The Morrow Project "vehicle batteries" can hold a lot of electricity, but are only carried on the control cars. If the battery bank of each control car is charged to 50%, the batteries still have capacity to absorb 90 seconds of "full power braking" by the train (presuming two control cars and all ten payload and equipment cars).

  • Otherwise, "resistor grids" are fitted on each car, including all the payload and equipment cars. These (hopefully) dissipate the energy generated by the wheel motors in braking mode. If they are overloaded, some resistors may break down -- which puts more electrical load on the remaining resistors. Spare resistors are provided to teams with Overland Trains, but dynamic brake "blowout" should be avoided -- it can cause fires in the electrical boxes, as the breakdown temperature is about 350 degrees C.


Control Car

Weight: about 35 tons

Length: 15.5 meters

Width:  2.9 meters over hull, 5.25 meters over wheels and sponsons

Height: 4.6 meters over hull, 5.8 meters to cab roof, 6.2 meters to clear retracted sensor mast

Ground Clearance (under hull):  0.76 meter

Turning Radius:  25 meters

Track Width:  4.3 meters; the tires are 3.5 meters in diameter and 1.2 meters wide

Wheelbase: 7.3 meters from first to second axle, 4.2 meters from second to third axle; note that the second and third axles do not steer

Ground Pressure:  5800 kg per square meter (about 8 psi); each wheel carries a weight of 6 tons.

Max Speed:

(road) 72 kph, although the operator's manual states that speeds over 45 kph are not advised, as heavy use of the dynamic braking system at this speed can damage the heat-dissipating resistors. A single "maximum braking effort" stop from 60 kph or more on level ground will definitely blow the resistor grids!

(offroad)    32 kph on flat gravel or dirt

9 kph across deep ruts or shallow trenches (up to 1.5 meters deep)

11 kph along or across low, small sand dunes (up to a half-meter high)

Fording:  4 meters

Gradient:  50%

Vertical Obstacle:  0.7 meter

Trench Crossing:  2.2 meters

Engines:  six 750 HP electric motors (one in each wheel hub, they are 560 kW three-phase asynchronous motors, with a maximum torque of 50,000 Newton-meters; each weighs 1.8 tons), powered by four Mk 2 Fusion Generators 

Suspension:  low-pressure high-flotation tires, ball joint arms, air bags and shock absorbers keep the ride reasonably smooth. 

Brakes:  primary is a dynamic motor brake -- the electric motors run "backwards" generating current, which either fills the battery banks of the control car, or heats resistor grids of the entire train. At least half of the resistor fans have to be operational for this to safely work. There's also a drum brake system, but it will wear out quickly if used a lot; and there's a mechanical parking brake, which cannot be applied while the vehicle is in motion. 

Bow Winch:  mounted at the bow of the control car is a winch capable of 30 tons of pull, at 30 meters per minute. The cable drum holds 73 meters of 28mm diameter cable.

Stern Winch:  capacity 16 tons at low speed (8 meters per minute), 3.5 tons at high speed (21 meters per minute); includes 35 meters of 19mm steel cable, and accessories (chokers for attaching logs or beams, etc.). Weight if removed, 1.2 tons. Also provided is a snatch block with hook, for 19mm rope or cable, 50 kg mass, capacity 35 tons. 

Crane: mounted at the rear, capacity 1.5 tons, with 20 meters of cable 

Electrical System:  24 volt, 110 volt, 240 volt. Utility power draw averages 12 kilowatts.

Batteries: 96 Morrow Project vehicle batteries, sufficient (if fully charged) to power the control car alone for about 12 minutes at full speed, or half of the complete Overland Train for 3 minutes, or to provide utility power for a week. The manual recommends that the batteries be kept at 50% charge, so that they can hold energy from the dynamic brake system.

Armament: four gun ports (right, left and two rear); two fittings for M18A1 Claymore mines

Armor Protection:  8.3mm high-hardness Cadloy steel, plus a polyethylene spall liner; cab windows 8mm polycarbonate; vision ports are 50mm thick armored glass

-- armor value 18; vision ports are armor value 16; cab windows are armor value 10


     Each control car contains living quarters for a crew of six -- including sleeping quarters with six bunks, galley and dining table for four persons, freezer, shower and toilet, and small clothes washing machine and dryer! The two "ground level" entrances (just ahead of the sponsons) open into small (about 0.9 m square:  1 person, or two very good friends) airlocks; there is also a roof hatch without an airlock. The vehicle has air conditioning and a complete NBC filter and decontamination system, and can support its crew while sealed for at least a couple of months with the supplies and equipment on board. A 1000-liter water tank is fitted, along with a sophisticated water filtration system, a 170 liter holding tank for the sinks and shower, and a separate 166 liter holding tank for the toilet. Several voice communication stations are installed, plus two television communication stations (one in the cab, one at the dining table), which connect all the control car with all the attached modules. The main doors can be locked and unlocked with Morrow Project ID cards; the roof and floor hatches can only be opened from inside.


Overland Train Control Car Interior -- lower level



     There are three bunks on each side at the rear, with lockers beneath and just ahead (they are all standard Navy enlisted bunk and locker sizes). The dining table swings up against the rear bulkhead; the roof hatch is over the table, the floor hatch is under it. Two small windows, with gun ports under each one, are set in the rear bulkhead.

     Going forward from the bunks, on the right side, are shelves for the computer, laserdisc player, television (which swings out on an overhead arm), and other electronics used by the crew. A wide storage "wardrobe" is ahead of that, then the pantry (which has a small window), and the refrigerator-freezer (10 cubic feet of refrigerator space). The space labeled "UTIL" has a 600 watt microwave oven, trash compactor, and storage for preserved food. Ahead of that is an open-front storage space; backpacks, sleeping bags, extra tools, supplies and ordnance brought aboard by the team tend to end up here.

     Forward from the bunks, along the left side, is a storage locker for weapons and other tactical gear (night vision, helmets, etc.); then the restroom, which includes a sink, medicine cabinet, toilet and shower. Another couple of small windows are in the restroom. The galley area has an electric 4-burner stove and oven, sink, food prep surface, and food storage cabinets. The space labeled "UTIL" on this side is the stacked clothes washer and dryer.

     The doors into the two "airlocks" are sliding doors (the external doors swing outside, and have small windows and gun ports). At the front are the steps up to the cab.

     The two side sponsons contain the resistors and fans for the dynamic braking system, plus some of the reactor cooling system. Note the Control Car has four resister grid units, though only three would normally be fitted for a six-wheel car.


     Keep in mind that there's a lot of equipment installed below the floor of the control car -- there's almost 12 cubic meters of volume under there. The fusion reactors are under the floor between the sponsons.


the driver's position within the control car cab


     The three-seat cab is fitted with a PRC-70 radio, PSC-3 satellite radio, headlights, external spotlights, horns, rear-view mirrors, voice and television communication stations, Autonav, Morrow Project computer, the largest chunk of electronics that guides the modules along the same path, and a sensor platform on an extensible mast. The mast carries a color television camera, PPS-5 radar, thermal imaging camera (mostly the guts of a PAS-7 thermal viewer), antennae for the PRC-70 and PSC-3 radios, infrared spotlight, speaker pair for the LSS-40 loudspeaker, and other equipment about 2 meters above the cab of the control car (7.8 m above the ground).


front view; the sensor mast is folded in this view


     A "caboose" control car can be slaved to a "lead" car and will track the same as a payload car or lab module. Note the control cars can only be attached to an Overland Train at their "rear" end -- the front doesn't have the couplings, power and control cables, etc.  The control car can be fitted with a snowplow/dozer blade on front. There is a small cargo crane (capacity 1500 kg) mounted at the rear of the control car -- mostly to assist in repairs and changing tires.

     The Overland Train is operated with the skill Drive Overland Train; members of Morrow Project teams issued with this vehicle will have a base skill of 40% in this (and can spend Personal Interest points on it if they wish). Operate Heavy Equipment can be used, at half skill or -10%, whichever is lower; Drive Truck can be used at one-quarter skill, or -25%, whichever is lower.


Payload, Equipment, and Specialized Cars


      The following information is common to most of the other cars. They each have four wheels, all powered (from the control car), with automatically-controlled steering and suspension. The Project terms the "cargo carrying" ones as payload cars; those with more machinery are equipment cars; those designed mostly as living quarters are called crew cars.

     The "deck" portion of all of these cars can be uncoupled from the "suspension" ends, allowing the car body to rest on the ground (or outriggers or jacks).


Weight: about 15 tons empty, max 25 tons loaded

Length: 16 meters

Width:  5 meters over hull, 5.25 meters over wheels

Height: 1.5 meters to deck

Ground Clearance (under hull):  1 meter

Turning Radius:  25 meters

Track Width:  4.3 meters; the tires are 3.5 meters in diameter and 0.6 meters wide, with central inflation system

Wheelbase: 12.5 meters

Ground Pressure:  5800 kg per square meter (about 8 psi) when loaded; each wheel carries a weight of 6 tons when fully loaded.

Max Speed:

(road) 72 kph

(offroad) 40 kph

Fording:  4 meters

Gradient:  50%

Vertical Obstacle:  1 meter

Trench Crossing:  2.2 meters

Engines:  four 750 HP electric motors (one in each wheel hub), powered from control car

Brakes:  primary is a dynamic motor brake -- the electric motors run "backwards" generating current, which heats resistors in the fan housings (one at each end of the equipment or payload cars). At least half of the resistor fans on the train have to be working for the dynamic brakes to safely work -- if too much load is applied, the resistors catch fire. There's also a drum brake system, but it will wear out quickly if used a lot; and there's a mechanical parking brake, which cannot be applied while the vehicle is in motion.

Electrical System:  24 volt, 110 volt, 240 volt

Batteries: none

Armament: none

Armor Protection:  mild steel body

-- sides and top are armor value 9; floor is armor value 18



Weight: about 16 tons empty, max 25 tons loaded

Height: 4.2 meters to roof. Interior height is 2.7 meters.


     The cargo space is 5 meters wide and 7 meters long, and can carry 9 tons of cargo in 94 cubic meters of volume. It is fully enclosed, with two 3 meter wide sliding doors on each side. While it is pretty well sealed when the doors are closed, it does not have any NBC filters, heating or air conditioning. Cargo straps and other handling equipment (such as ramps) are carried in boxes and brackets under the deck; cargo tie-down points are fitted to the floor and ceiling. There are 110 volt electrical outlets inside the car, and work lights on the ceiling.

     Four leveling jacks are fitted, one at each corner, for use if the car is off of its suspension.




     This has a cargo platform 5 meters wide and 7 meters long (designed to carry two ISO 20' cargo containers side-by-side, or 4 CONEX boxes), with stake pockets all around the edges, and can carry 15 tons of cargo. Cargo straps and other handling equipment (such as stakes, stake sides, and four 0.7 meter wide ramps for smaller vehicles) are carried in boxes and brackets under the cargo platform. There are outlets for electrical accessories on the cargo boxes and along the deck midline. Three mounting plates on the deck allow HIAB cranes (around 1 to 4 ton capacity), Mk 2 Mod 1 mortars, or other "mounted" items to be carried.


The U.S. Navy used the same mounting system to attach 40mm Bofors guns onto their version of the 20 meter patrol boat.


     Four leveling jacks are fitted, one at each corner, for use if the car is off of its suspension.

     A common flatcar accessory -- but not carried on every flatcar -- is a "heavy tow truck" frame, which takes up about 2 meters of the length of the bed, and allows the flatcar to tow heavy highway trucks.





     Weight:  23 tons with counterweights fitted.



     Rotating crane with four stabilizer outriggers; four-section hydraulic boom, retracted length 10.8 meters, extended length 42 meters (rotation pivot is 3.3 meters from one end of the deck). Cable length 200 meters, cable is 19mm with maximum permissible line pull of 5860 kg. Actual lifting capacity depends on equipment setup and boom angle/distance, but typically about 9 to 35 tons.

     Maximum power load is about 100 kilowatts, with a typical load of 20 kilowatts. 120 Morrow Project vehicle batteries are fitted (in a box within the car deck), to allow the crane to operate away from the control cars for at least eight hours of steady work. If this car is not attached to any other modules, it can be driven - slowly, and for short distances - from the crane cab; this uses up electrical power pretty quickly.

     The one-person cab has tinted polycarbonate windows, windshield wipers for the front and top windows, window defrosters, heater and air conditioning, dust filters on the air intakes (but not a full pressurized gas-proof environment), a handheld fire extinguisher, an AM/FM radio, floodlight controls, outrigger controls, etc. The cab has Resistweave fabric lining on the sides, and roll-down Resistweave curtains for the windows; additional armor plates can be added to the cab sides if needed (but the operator's vision is very restricted by these covers).

     An amber strobe beacon on the cab, two floodlights on the boom head, and working lights on the outside of the cab allow the operator and crew to see what they're doing.

     Includes a 3.8 ton counterweight; 643 liter hydraulic fluid reservoir, and minor accessories and tools stored in shallow boxes on and under the deck. A team with this equipment car will usually have space on payload cars dedicated to more accessories for this car. Armor value 9 (when armor flaps are in place on operator cab). Some (not all) of these accessories and options include:


crane car accessories and supplies

hydraulic fluid, filters, and other hydraulic system consumables

spare top and bottom boom wear pads:  10 is a complete set

4-sheave quick-reeve hook block with safety latch, 35 ton capacity

various hook balls

various endless polyester rope slings, nets, etc.

spools of 9mm and 19mm wire rope

20 wire rope slings, 25mm cable, 3m long, working load 9 tons

20 shackles, 25mm, working load 12 tons

250 kg headache ball (aka wrecking ball)

forklift attachment for boom head

50 meter heavy power cable (mass 25 kg) -- same as used for the Mk 3 laser

6 steel covers for the cab windows


crane cab armor value 10 points, including windows; 18 points if steel covers are installed.


Repair Module

Weight: about 20 tons empty

Height: 4.2 meters to roof.

Electrical System:  24 volt, 110 volt, 240 volt. Utility power draw averages 1 kilowatt. Powered from Mk 1 fusion generator.

Batteries: 20 Morrow Project vehicle batteries, sufficient to provide utility power for 8 hours

Armor Protection:  8.3mm high-hardness Cadloy steel, plus a polyethylene spall liner

-- armor value 18


     The actual inhabitable space is 5 meters wide and 7 meters long, with a headroom of about 2.5 meters; there are no airtight internal divisions. One side has two large cargo doors; the other side has a single cargo door and a personnel door; the cargo doors hinge upwards, to provide shade and protection from rain. Spotlights are fitted on each side and end, plus on the undersides of the cargo doors. Each repair car is fitted with a Morrow Project computer and Laserdisc drive (and 30 Laserdiscs with technical references and diagrams), air conditioning and a complete NBC filter and decontamination system, and a 200-liter water tank and filtration system. Note that if the interior is contaminated, decontamination is very tedious; only the personnel door has an airlock, and the supplied curtains don't provide much isolation. A voice-communication station (i.e., a telephone) and televison communication station are installed, along with two floor-mounted chairs, two fire extinguishers, and a small sink. At each cargo door are two fold-down work surfaces, to be used by technicians standing on the ground next to the module.

     Four leveling jacks are fitted, one at each corner, for use if this car is disconnected from its suspension.

     There are several electrical outlets and communication jacks; specifically, there is a socket at each corner of the body for the Mark 1B laser.

Medical Module


     Usually only found as part of Science division vehicles.


Other Cars


      Some of the other various bodies available are: 


  • power station, with fusion generator Mk 3, armor value 18; it looks rather like the (pre-Morrow Project) power car.

  • shelter body (usually called the "crew car" by Project teams, it has crew quarters with 20 bunks), with NBC protection and armor value 18.

  • television and long-range radio transmitter station, with NBC protection and armor value 18.


     The following cars were built in limited numbers -- most were one-of-a-kind, or were obtained from the original Army version. For various reasons the Project decided not to go forward with further construction, but these are probably in a depot somewhere.


  • 12 yard side dump body, armor value 10

  • 3000 gallon tank and pump body; this was the original fuel source for the Army's Overland Train. Armor value 9.

  • 3500 gallon tank body with water distributor option, armor value 9

  • enclosed cargo, with 2.7 m high interior (4.2 m to roof) and roll-up doors on both sides, armor value 9.

    • the Project decided not to use this design, as it proved difficult to keep it environmentally sealed. It was probably converted to a regular sliding-door boxcar.

  • refrigerated/frozen food body, armor value 9

  • compactor/roller

  • grader/scraper




  • A dolly converter, allowing regular commercial or military "fifth wheel" semi-trailers to be towed behind any Overland Train car -- except for "trailing end" control cars. Note that any trailer hauled this way won't be self-steering, and that reversing will be very difficult. These can also be used as "regular" dolly converters behind military on contractors' vehicles.

  • An electrically-driven winch is available, in a steel housing with bolt-down corners. It can apply 4500 kg of pull (yes, units, I know); maximum line speed is 3.6 meters per minute. A snatch block is furnished, which doubles line pull for heavy winching requirements. The winch cable is 40.6 meters long, 9.5mm diameter, and weighs 12.9 kg. The entire winch unit weighs about 50 kg. This comes from the Project's pontoon equipment.

  • There's a little one-man "pilothouse", with driving controls, dome light, and headlights; heater; windshield wiper; electric fan; outlets for 12 volt DC, 24 volt DC, 110 volt AC. Note that it's not sealed against fallout or contamination. Aluminum construction (10 points of armor), windows are 8mm thick polycarbonate (armor value 10). Mass, 200 kg. This also comes from the Project's pontoon equipment.

I think they forgot to design a car for doing all the paperwork that comes with keeping inventory of everything.

Do you have a floor plan for the small upper level?

No. It's mostly three seats: the driver, the observer (radar, computer, etc.) and the ... uh ... commander chair (radios, mostly). I'm still looking for more interior-of-cab photos.

Not sure these can be seen except on a specific root ...

Just behind the cab? Part of the cooling system for the reactor and motors, and the air conditioning unit for the crew. I suspect that, unlike locomotives, the cooling system vents hot exhaust downwards (to prevent sucking up lots of dust). Keep in mind that the original (real-world) Overland Train had all the fuel-burnin', power-makin' stuff on dedicated cars at the rear of the train.
