VIA Rail 6148 began it's life as an RDC-5 on the Canadian Pacific Railroad.  Unlike the other RDC configurations, RDC-5s were built without control cabs at either end.  It was later converted to an RDC-2 and then again to an RDC-1. 

The control cabs in 6148 feature fold down seats.  The seat moves out of the way when the cab is not in use to allow passenger access from either side of the train.  This is a different design than that of the RDCs used by BC Rail.

The numbers above the windshield indicate we are on the "B" end of RDC 6148.  The controls on the left govern the engine while those on the right operate the brakes.
