*WARNING: LONG POST*
I have a Trainz map from Bethlehem to Philadelphia, that was the original commuter rail route but Conrail/SEPTA cut it back to Quakertown, then Lansdale at the end of June and July, 1981. Budd RDC's as well as an FP7 trainset (Reading FP7's are at Steamtown, they visited Emmaus-Pennsburg twice to pull excursions, the ex-Reading coaches are at a museum in Danbury, Connecticut) were used for trains that went north of Lansdale. The train even went to Allentown from June, 1978 to Sept. 1979 the experiment failed because too few riders were using the train from Allentown and the station was in a poor location off of Union St. south of Hamilton St. bridge at the former Lehigh Valley Railroad station platform. There was what looked like a bus shelter with a blue with white letters sign that said ALLENTOWN in a photo in a book I have and a white wood sign saying Future site of Allentown rail station which never happened. I believe the sign remained until several years ago, I remember seeing it as we crossed over the RR crossing at Union St. heading west. I don't think we'll EVER see SEPTA trains go to Bethlehem again, on their site they even state that Bethlehem is outside of their service territory in a question about transportation to the BethSands Casino. Remember, trains ran to Bethlehem before the SEPTA takeover which occurred in January, 1983. The trains at the time, both electric and diesel were operated with Conrail crews under contract with SEPTA and subsidized by PennDOT from Apr 1976 until January, 1983. SEPTA still owns the ROW to Hellertown (tracks removed from below Coopersburg along Rt. 309 to Hellertown for rail trail and tracks removed through City of Bethlehem to Union Station for greenway project) Tracks from Quakertown to Telford operated by East Penn Railroad, and Telford to Lansdale (as well as trackage rights on SEPTA to Warminster, PA) by Pennsylvania Northeastern Railroad a subsidiary of New Hope & Ivyland I believe. They just started last year, taking over from CSX in Lansdale. There is still a possibility for commuter service from Shelly to Lansdale since tracks are still in but would need rebuilding to handle higher speeds plus the section north of the industrial park in Quakertown is out of service and two crossings would need reopening (they were paved over in late 1984 or so after freight service by Conrail ended between Quakertown and Hellertown in Oct 1984) Conrail stopped running to Qtown in 1997, hence the short line takeover. However, Conrail continued running to Telford then CSX from 1999-Aug 2011.
My Trainz route will feature the (former) R5 line between Colmar at Rt. 309 and 30th St. and the currently freight only line from Lansdale to Quakertown and the abandoned part north of there, and the rail trail in Lehigh and Northampton Counties. Some parts of the other SEPTA Regional Rail branches on the former Reading side might be included. As for coaches, the King Industries coaches have a full rideable interior, but no pantographs. I have a Silverliner beta that was available for download but the link no longer works if it can be found. And there are SEPTA coach/cab reskins on DLS which are supposed to be the push pull coaches that are hauled by AEM-7's which SEPTA got in 1987. An Amtrak AEM-7 could be used as a substitute or reskinned for personal use. The Amtrak AEM-7 is available at an Amtrak Trainz site I believe there was also one by connyxy woman from Europe but her downloads are no longer available. There are better Amtrak amfleets on one of the Amtrak Trainz sites anyway. And you can ride in them, conny's you couldn't, no interior camera view. And better than Magicland's payware versions as well. Interior is better than Magicland's. I like eastern PA railroading, I'm also working on CP and Steamtown routes from Sunbury to Scranton and Binghamton, NY as well as Carbondale, PA and Delaware Water Gap, PA. And I have Reading and Northern, Norfolk Southern routes combined from Manville, NJ to Reading, PA (section to Harrisburg unfinished), and Sayre, PA to Jim Thorpe and Reading, PA. I hope to have all major rail lines from Philadelphia to Scranton and Binghamton in three different routes. (The R&N-NS route uses routes by Roon-Josh Drumm and DEM that I generated to fill in missing sections to join the routes together)
