Large Flat Cars Cars
Flat cars are designed to carry oversize loads.
In researching these special freight cars, I have put together a lot of information.
ARA Flat Car Listing
"FD" - Depressed center flat car of special construction having the portion of floor extending
between trucks depressed to provide necessary overhead clearance for lading.
"FM" - Ordinary flat car configuration.
May have multiple axles and/or trucks.
This car has flooring laid over sills and has no sides or ends.
