Thanks!  Are there O scale models of these?

Mth and overland brass are the only ones I can think of in o scale / o gauge.  Plans for the MHC were in an issue of Model Railroader when they first appeared.

Gotcha.  OK, thanks.

That is a plug door.  It rolls on a track, but when it gets to the doorway cam action forces it inward into the opening.  The door has rubber seals all the way around it. To get a good air and water tight seal around the door a good deal of force can be  required to cam the door in tight. The big wheel replaces the three foot piece of pipe most people dealing with these doors used. 

The MTH car has hankering for one; and was thinking of 3D printing them, as well as replacement steps.

looks like the door wheels got added when the steps were changed.
