O scale model of the Kasgro #370359 12-axle heavy duty flatcar
The prototype KRL #370359 flatcar is a 12-axle railcar that has a load limit of 744,000 pounds.
An O scale model has been built of this car using MTH roller bearing trucks. The 12-axles distribute the weight so that the car tracks quite well with a load installed.
