Has anyone run these budd engines with passenger cars next to subway trains. I was looking at one on line and was wondering how they would look running side by side. The budd almost looked like it could be a subway train but I don't know how the size would compare to a mth nyc subway train. Are the doors even when pulling in a station to a subway car?

If you are talking about the Budd RDC cars there have been many produced by different manufacturers. There has only been one produced in true scale dimensions which was 3rd rail. Lionel , K-Line and MTH have all produced scaled down version that measure approximately 15 inches long. The height of the doors is about equivelent of any of the subway sets except the R62. There was also one produced by Marx and RMT that is tiny compared to the rest and sits lower on the door height

One of the problems I've seen in subway and scale model railroading is the variation of floor heights among the various ready to run products.

In real life, the car floor heights were rather uniform, whether for feight or passenger service. So too station platform hights were similarly uniform.

At the SIRT St. George Terminal, the station platforms for MUE cars is the same height as that for BMT subway cars, as well as for B&O mainline passenger cars. A few of them did make rare visits to St. George over the years.

One such visit was in 1955, when a four car special for B&O Accounting Department staff from Baltimore arrived at St. George. They were on a New York Terminal inspection and field trip. This was yet another instance of mainline railroad equipment and 'subways' operating on the same tracks.

So an RDC and a subway car should essentially have the same floor height and be able to work the same station platforms. But alas in modeldom, it can be at times an imperfect world.
