Strange yet appealing "siarknose" design by Raymond Loewy gives the PRR duplex a unique look. Here it's ready to pull the trailing passenger train, sometimes hitting 80-100mph speeds. Date is approximate |

| Description: |
This later T1 duplex was built by Baldwin in 1942. The exterior styling was designed by Raymond Loewy, According to SteamLocomotive.com " The theory behind the duplex drive held that reducing the masses of reciprocating (e.g., main and side rods) and revolving (e.g., cranks and counterweights) would reduce hammering and raise speed. Tests run at a high boiler pressure and late cut-off showed 6,110 drawbar horsepower at 85 mph. In service, these engines could be fast, powerful, and smooth, pulling 910-ton passenger trains at 100 mph. According to most sources, the divided drive proved to be a major maintenance headache, however, because no way could be found to stop one or the other driver-cylinder set from slipping, either starting or, more alarmingly, at high speed. This liability proved fatal to the chances for real success for these engines, and they were retired well before the much earlier vintage K-4 Pacifics." Roger D. Kruger photo |
