900, 902, and 903 were all used in pull-pull service between Reading and Philly. Plus, when SEPTA took them over when Conrail began, between Bethlehem and Philly when the RDC's couldn't actuate signals on the Bethlehem Branch because no other traffic burnished the rails on that branch. They were painted in SEPTA's gaudy white with a segmented red/orange and blue stripe. (yeesh) Both the Lancaster and Philly chapters acquired them from SEPTA, who stored them in the Philly jungle where every piece of copper and brass that could be easily removed was, by the "local inhabitants". They sat at Strasburg for a while, painted in "dip" black then 902 and 903 were restored nearby. 900 was eventually sold to the RCT&HS, where it awaits restoration, once someone wants to "adopt" it, and replace all that missing wiring!
