I am aware of Reading Transit and Light 102, which is currently at ECTM (although I have no idea of condition other than a small paragraph on the website), and of number 182, which I have posted about on here in the past. I am also under the impression that Reading is looking to start it's own vinatge trolley operation. Any info appreciated.
Allow me to add some info:
Reading 102, a 1918 Brill, is in the posession of ECTM, awaiting eventual restoration.
Reading 506, a 1920 Birney, is also at the ECTM and is displayed as a 'cut-away.'
Reading 511 was the 'Trolley Stop' diner in Skippack, PA, and is now part of 'Hotel Fiesol.'

Reading 182, a single truck Brill, had been converted into a cabin of sorts, and as far as I know it is still there.
