OnTrack was operated with four Budd Rail Diesel Cars (RDC-1) "Buddliners" built in the 1950s.
All OnTrack cars were owned by the New York, Susquehanna and Western Railway and returned to NYSW upon the demise of the commuter rail service.
By 2008, the RDCs were either sold or out of service.
The Orange Express required longer trains and used retired Metra passenger cars, pulled by various NYSW locomotives.
