According to this EL database, at least three ex-Erie RS-3s were rebuilt into RS-3ms. I think CR scrapped them, but don't know when.lvrr325 wrote:At least one of every Conrail road that had these got done - LV, RDG, CNJ, Erie and DL&W, and PC. I'm not sure how many are left outside of former LV-211 (actually a PC/PRR unit before that) in Rochester, an ex-DL&W on Housatonic, and 2 or three on the Maryland & Delaware (I believe one each DL&W and Erie and not sure on the other one). At least two of the Amtrak units do exist, and those were PC units originally.
There are 5 ex-DL&W RS-3ms still in existence, as you can see here:

Three are on the Maryland & Deleware. One is at a museum in Danbury, while the outher is Housatonic unti you mention.
There are also 2 ex-PRR units rebuilt as RS-3ms (including the famousLV #211): http://gold.mylargescale.com/Scottychao ... /index.htm
The NDC RR in Pennsylvania has an RS-3m, which is either ex-RDG or ex-CNJ.
