I understand the Budd company frowned on this practice as in "void the warranty" in much the same way they discouraged hauling non-RDC trailers in RDC powered consists (CNJ and NH famously getting in "trouble" for this) I'm looking at a calendar (weekend chief's nyc 2006) photo of a pair of NYC mu's towing an RDC up the Harlem Div, to cover schedule north of N.White Plains; I know the Rock Island did the same between Kansas City and Ft Worth, anyone else know of other road's operations like this? NH maybe?
Historically? I am not aware.
Presently? The Port of Tillamook Bay has pulled its RDC-1 behind a steam locomotive (with the steam engine doing the work); and at least on one or two occassions, the Lewis & Clark Explorer Train had to be pulled by a GP39-2 (from host railroad Portland & Western RR) due to multiple engine failures underneath the RDCs.
