Pat's Trains announcement of some RMT Tank cars made me take a closer look at one of their other freight cars. Along with Beeps, Feeps, and Peeps I have a few freight cars lettered for Bethlehem Steel including this hopper car as well as a caboose and depressed center flats with tanks.
I can attest the trucks are all metal with the exception of the air hose and brake rigging on the underside. The sideframes are one piece with non functional springs inserted. Uncoupler is hidden. Coal load was included and hopper doors open. Pretty impressive they can produce a car like this at this price point. I will be ordering a few tank cars.
