Now I have to admit when the South Shore Line was built in the late 1960s, was it based on the same concept as
PATCO, running a 3-track ROW open cut through Haddonfield with the NJT (PRSL) only a single track with two rail
transit tracks? The same configuration applies in Quincy with the double track Red Line and single track
commuter rail.
PRSL and early NJDOT/NJT to 1981 had RDCs from Atlantic City, Cape May and Ocean City use the Lindenwold terminal, with a PATCO connection to Camden and Center City. Atlantic City service was suspended 1982-1989 but resembled with the same PATCO connection until NJT started running through service to 30 Street Station in April 1995. Was the South Shore also designed for this, with diesel passenger trains to points south connecting to Red Line at Quincy Center or Braintree instead of direct service to South Station?
Recall the South Shore was seen as a quasi-interurban when under development in the late 60s like PATCO, hence the No. 1 series 01500s being designed to run as single units for low density if need be and the interiors in a more suburban configuration.
