You must be qualified to the next interlocking past the end of the line in the case of a failure of the interlocking before the end point. In the case of the Newark line, RUTHBY interlocking is what trains normally use to crossover for the return trip but in the case of that interlocking failing, the crews would be qualified to travel down to BACON to turnback their train.

My initial thought was "Kinda odd to turn at BACON, as going south/west it thins down to two tracks. Wouldn't it turn at PRINCE?" But then there's been a few instances where the Perryville-bound MARC had to go up to PRINCE to turn and make the stop as PERRY was stuck. So there's president.

Crews must be Qualified COMPLETE Interlocking to COMPLETE Interlocking on Amtrak Territory. BACON is the next complete interlocking after Newark. Trenton is HAM, Thorndale is CALN.

Total passengers by station for 2015

Ardmore - 61,129

Paoli -174,833

Exton - 112,253

In comparison, Lancaster and Harrisburg see over 500K per year, and N. Philly = 832.

Ardmore's 61K is not too bad considering not all trains stop there and about the same # as Middletown, Mount Joy, and D-Town.

Just about every person that boards an eastbound Amtrak at Ardmore are traveling further then Philly. Majority stay on the same train with the minority transferring to another train. Daily Ardmore - NYC commuters has dropped significantly in years and I assume that is why only one eastbound train in the morning stops there.

It would be great to see SEPTA trains run to Lancaster or Harrisburg as local service and eliminate some of the stops Amtrak has to make, such as Ardmore and Exton. Perhaps with some sort of combination we could get hourly service and later service.

You don't need SEPTA to run all the way to Lancaster and Harrisburg to accomplish what you're proposing.

ekt8750 wrote:Correct. Trains regularly turnback at CALN which is just west of Thorndale Station but they have to qualify out to PARK. As for Parkesburg service, yeah part of the reason they ended service out there was the lack of interlockings beyond Downingtown. Before CALN was built for Thorndale service, there was nothing between Downingtown and Parkesburg and then nothing after that til Strasburg with LEAMAN interlocking. I remember there being a few midday Parkesburg runs where trains couldn't use PARK interlocking due to scheduling issues and had to go all the way out to LEAMAN to turnback.

There's been talk on and off about extending service to Atglen (which would require building a station). That would split the difference between PARK and LEAMAN but who know's if there's enough ridership to justify doing so.

CALN has been in around since the P&T was built and believe the trains switch over east of the station at THORN tower. I do not know if it is standard practice now, but when first opened, every westbound that was to return to service eastbound would switch over, alight, and board on the inbound side. Only westbound trains that would deadhead back eastbound would use the outbound platform.

Also, I vaguely remember that when SEPTA had service to Parksburg LEAMAN was not used as a turnback and SEPTA crews had to be qualified all the way to Lancaster. I am not sure about this one.

Also, wasn't Leaman hand-thrown until quite recently? A time-consuming operation for turning trains back.

That is correct. I forgot all about that. That's why crews had to qualify all the out to Lancaster when there was still Parkesburg service.
