1900 to 1960s, if any traditional Doodlebugs were still running in active service by then)

PRR ran them between Trenton, NJ and Red Bank, NJ until May 1962. Route was Trenton - Monmouth Jct. - Manasquan - Red Bank using the (now) NEC, the Freehold and Jamesburg Agricultural RR (now Conrail CSAO Freehold Secondary truncated at Freehold; Freehold to Farmingdale OOS; Farmingdale to Manasquan removed in 1963) and the NY&LB (now NJT North Jersey Coast Line).
