The Q2 4-4-6-4 was the most successful example of the duplex locomotive constructed by the PRR. Production locomotives followed from the end of 1944, but these were rather different, the lesson that backward-facing cylinders next to the firebox were a poor design choice made clear.
The PRR S1 class steam locomotive (nicknamed "The Big Engine") was a single experimental duplex locomotive of the Pennsylvania Railroad. It was designed to demonstrate the advantages of duplex drives espoused by Baldwin Chief Engineer Ralph P. Johnson. [1] The streamlined Art Deco styled shell of the locomotive was designed by Raymond Loewy. [1 ...
This split the locomotive's driving wheels into two sets, each with its own pair of cylinders and rods. Until then, the only locomotives with two sets of drivers were articulated locomotives, but the duplex used one rigid frame. In a duplex design cylinders could be smaller, and the weight of side and main rods could be drastically reduced ...
Pennsylvania Railroad 5550 (PRR 5550) is a mainline duplex drive steam locomotive under construction in the United States. With an estimated completion by 2030, the locomotive will become the 53rd example of the Pennsylvania Railroad's T1 steam locomotive class and the only operational locomotive of its type, [7] as well as the largest steam locomotive built in the United States since 1952.
The duplex propensity to slip was combated by an automatic slip control mechanism that reduced power to the slipping unit. The Q2 locomotive was 78% more powerful than the locomotives that PRR had in service at the time, and the company claimed the Q2 could pull 125 freight cars at a speed of 50 mph (80 km/h). [5]

Locomotive Duplex was an experimental 4-cylinder steam locomotive designed by John Haswell of the Austrian State Railway Works at Vienna and built in 1861. It was exhibited at the 1862 International Exhibition and was then used on the line from Prague to Podmokly (part of Děčín today) where it worked till 1900. [1]
