The Central Railroad of New Jersey, the precursor to some of NJ Transit’s system, operated passenger trains at a financial loss for thousands of commuters that patronized its system. The Budd Company developed the Rail Diesel Car (RDC), a self-propelled passenger car, which could be operated more economically than an entire train. The 556 was built in 1956 and was among several such cars owned by the CNJ. Later owned by NJ DOT, 556 had the distinction of being part of the last run of the “Bayonne Scoot” in 1978 – a shuttle between Cranford and Bayonne inaugurated when the CNJ rerouted its trains out of Jersey City and into Newark Penn Station. The car was donated to URHS by NJ Transit in 1991 and is currently stabilized and stored in URHS’s Boonton Yard.
