| RRMP. Here is an original photo that I took at the Railroad Museum of Pennsylvania in Strasburg, Pennsylvania, on 30 June 1973. Shown here (L to R) are Pennsylvania Railroad engines #4781 and #4780. They are permanently-linked DD-1's built in Juniata during May of 1911 and rated at 3,160 horsepower. #4781's original number was "3937," while #4780's was "3936." According to the RRMP, "The Museum is home to DD-1's Nos. 3937 and 3936, built in 1911. These two locomotives formed a married pair and operated in the tunnels beneath the Hudson River between New Jersey and New York City until being relegated to yard work in 1924." Visible in the background is one of the RRMP's exhibit halls during its construction. |
