That green pedestrian bridge was done by Plasticville about 20 years ago. They show up at train shows and on eBay from time to time.
Here are several photos with Pennsy flavor from around my Pennsylvania & Western layout. Click on any photo to see a larger version.
Double-headed Weaver H10s 2-8-0's approaching the grade crossing in Franklin, PA.
MTH AS-616 with custom Trainphone equipment added, new engineer figure and corrected cab number.
A pair of 3rd Rail H6sb 2-8-0's are on the inbound steam service track in Annville, PA.
A 3rd Rail I1sa 2-10-0 is stopped at an intermediate signal between Lebanon and Summit, PA. The signals on the left display an Approach indication, meaning that the Yard Limit Signals into Annville are set to Stop. The signals are from Custom Signals.
This is the freight station and Railway Express office in Summit, PA.
A K-Line B6sb 0-6-0 works the yard in Annville, PA.
T1 4-4-4-4 #5511 (3rd Rail) drifts into the station at Lebanon, PA. My layout is set in the 1949-1953 time period, and highway stop signs of that era were yellow with black lettering and sat on a short 4-foot post. Quite different than today!
This is the interior of the Korber roundhouse in Annville. It looks like a quiet day.
