| Here is a photo taken by Mr. Bert Pennypacker. It was published originally in the December 1951 issue of "Trains & Travel" magazine, page 8. Partial Caption: "Pennsylvania No. 4996 (above) is one of four new experimental 3000 h.p. electric freight units being built for the road by Westinghouse. It has been tagged a 'substation on wheels,' because its pantographs draw A.C. power from the catenary and a mercury rectifier tube converts it to D.C." which then powers the traction motors. #4996 is an E-3B (B-B-B) built by Westinghouse and Baldwin-Lima-Hamilton in June of 1951 and retired in June of 1965 after just 14 years of revenue service. The date and the location are not recorded. |
