8020 PRR T1 Duplex, #5500, Paragon4 Sound/DC/DCC, N

With the goal ofdeveloping more powerful motive power for express passenger service, thePennsylvania Railroad introduced the class T1 Duplex 4-4-4-4 in 1942 with twoprototype locomotives, and followed in 1945-1946 with 50 production models. Built with striking streamlining designed by Raymond Loewy, the T1 engineswere large, powerful, and fast!

The T1’s were duplexlocomotives – this means they had two sets of drivers, each with its own pairof cylinders and rods.However, the T1s were not articulatedlocomotives, but used one rigid frame.With this design, the cylinderscould be smaller and the weight of side rods and main rods could be reduced. This duplex design with lighter machinery, shorter cylinder stroke, less wearand tear due to small moving parts and the use of poppet valves allowed theT1’s to travel at extremely fast speeds.Unfortunately they were alsoprone to wheelslip and maintenance issues that the Pennsy struggled to workthrough – especially the fact that the poppet valves could not withstandsustained operation at 100 mph speeds.These problems likely could havebeen resolved with some modest design changes, but the PRR, and steam ingeneral, ran out of time.In 1948, the PRR dieselized all of itsfirst-class prime trains and the T1s were downgraded to haul secondary trains.Some were withdrawn from service in 1949, and all were retired by 1952.

In 2023, Broadway Limited is building ourthirdproduction of Pennsy T1 Duplex models, and our first production withour Paragon4 Sound/DC/DCC system.We are building five models intraditional DGLE paint and Pennsy lettering, one Unlettered model that will bepainted DGLE, and three models decorated in fantasy paint schemes based onwell-known PRR paint schemes.All models will have prototypicallyaccurate sounds for a Pennsylvania Railroad T1 Duplex 4-4-4-4.
