what is it?

The RP-210 was a streamlined 1,000 hp (750 kW) locomotive built in 1956 by Baldwin-Lima-Hamilton, specifically to operate with the experimental, all-aluminum Train-X coaches that were built by the Pullman-Standard Car Manufacturing Company. The model represented Baldwin's attempted entry into the lightweight passenger locomotive market, but only three of the low-slung diesel-hydraulic units were produced. The first RP-210 was built for the New York Central Railroad to power their Ohio Xplorer train between Cleveland, Columbus, and Cincinnati, and a pair was purchased by the New York, New Haven and Hartford Railroad to double-end their Dan'l Webster, running between New York City and Boston.

fun facts

  • First built 70 years ago, in 1956.
  • Top speed is 1.5× a car on the Dutch motorway (130 km/h).
  • At full speed it would cover Amsterdam–Utrecht (≈ 40 km) in 12 minutes.
  • 746 kW is about 9 family cars (~85 kW each) flat out.
  • Weighs about as much as 15 African elephants (~6 t each).
  • 17.7 m long: about 4 cars parked nose to tail.

diesel locomotive: A diesel engine on board drives the wheels, usually through a generator (diesel-electric).
