The ordinary flat car is a simple and versatile type of railroad freight car. Despite the versatility of the ordinary flat car there have been special uses that have lead to the development of special types of flat cars for carrying certain types of loads. In this installment of the O Scale Freight Car Guide we will wrap up our study of flat cars by reviewing O scale skeleton, bulkhead end, center beam and heavy duty flat cars.
Skeleton Log Cars
Skeleton log car were once used by both logging railroads and common carriers to transport logs to mills. Three rail skeleton log cars present challenges to 2 rail and 3 rail O scale modellers. The lack of a car deck puts over sized flanges out in the open. Lowering a skeleton car onto more prototypical trucks and mounting Kadee couplers can be a challenge.
The K-Line 663 skeleton log car is the only model of this type long enough to make it representative of the majority of log cars used in the Pacific Northwest. Add on high steel bunks were also available for those modeling operations from the 1950s to the end of the 20th century. Today this car is available from Williams by Bachmann.
The Lionel skeleton log car features diecast construction.
MTH has typically offered their ABS bodied skeleton in six car sets.
Bulkhead Flat Cars
Bulkhead flat cars became common in the 1960s. By adding bulkheads on each end of a flat car railroads dramatically reduced the hazards to personnel, structures and equipment from shifting lumber, pipe or other loads. We have several models of bulkhead flat cars to chose from in O scale.
The Atlas pulpwood flat car was first produced in the year 2000. This Master line model has a V-shaped sloped deck that is evident when it is unloaded. It's short length makes it a full O scale model than can handle O-27 curves.
The Atlas Trainman 62' flat car debuted with high bulkheads in 2011. It weighs in at 23 ounces. A short bulkhead version was introduced in the second production run. The three rail version is advertised as requiring O-54 and the two rail versions needs 36 inch minimum radius curves.
Lionel offers a version of their diecast PS-4 flatcar with short bulkheads. It weighs 26 ounces with a pipe load.
MTH introduced their bulkhead flat car in the 2000 Volume I catalog. They have come with packaged lumber, pipe or track panel loads. They weigh 21 ounces with a simulated lumber load. Recent versions have improved trucks and underframes designed for Kadee coupler mounting and conversion to 2 rail trucks.
Weaver has offered their flat car with bulkhead ends in 2 rail or 3 rail.
Center Beam Flat Cars
Center beam flat cars became common in the 1970s as an ideal car for shipping fork lift loaded lumber. The MTH Center beam flat car first appeared in the 1998 Volume III catalog. Two versions have been produced, one with oval “opera window” openings in the center bean and the other with a truss type center beam. The MTH center beam flat cars have come with lumber or pulpwood loads. Recent production runs feature updated trucks and underframes with prototypical inboard truck positioning and Kadee mounting pads. Weight is 22 ounces empty and 36 ounces with a pulpwood load. Despite their 72 scale foot interior length and 80 feet over the couplers MTH states that they will handle O-42 curves.
Heavy Duty Flat Cars
We have several models of multi-trucked heavy duty flat cars available in O scale.
The K-Line 693 Diecast 16 Wheel flat car has been continued as a K-Line by Lionel offering. K-Line offered several different loads including lubber, I beams and booster rocket stages.
K-Line 692 Diecast 16 Wheel Depressed Center has also appeared under the K-Line by Lionel banner. In addition to ore typical loads at least two road names were offered with a ship propeller load.
MTH introduced their 47' Heavy Duty QTTX flat car in the 2003 Volume 2 catalog. It has come without a load or with everything from heavy equipment to space shuttle SRB segments.
The MTH 75 foot Depressed Center flat car debuted in the 1998 Volume 2. It comes with a transformer or heavy equipment load.
MTH first offered their model of the massive 28 wheel Schnabel car in the 2000 Volume 1 catalog. The Schnabel car has two ends that connect to the transformer load to make a single unit for transport.
As always, your comments or corrections are most welcome. And let's see photos of your flat cars.
