The experts were probably right. CCM wouldn't have been a great commuter line as you can't serve the suburbs here by rail the way rail serves the city. Too much sprawl.
However, perhaps the experts were looking at the Trenton Cutoff using the wrong lens. The cutoff has some value in a shortcut between Harrisburg/Lancaster and NY. A station in Plymouth meeting, Willow Grove, Southampton or Oxford Valley that provided one seat service to Harrisburg/Lancaster/NY would be very attractive, probably as attractive as a station at Jenkintown or Langhorne that touched NY as well.
