Pennsylvania Railroad T1 Duplex (4-4-4-4) Steam Engine #5544, one of the Sharks of the Pennsylvania Railroad.
The powerful PRR T1 steam engines were designed for one thing - speed. Their massive boilers and split driver design were capable of hauling 910-ton passenger trains at speeds in excess of 100 mph. In fact, they rank as some of the strongest, fastest steam engines ever produced.
History has not been kind to the T1, as they has been labeled as locomotives with heavy and even uncontrollable wheel slippage, even at speed. However, a recent article published in the Chesapeake and Ohio Historical Magazine has shed new light on the performance of the T1, and that they did not show any sort of excessive wheel slippage while being tested by the C&O.

The PRR T1s were designed with a rigid wheelbase, but unfortunately LEGO's tight turn radius forced me to articulate her. Still, I am very pleased with the results.
I started working on this design in April of 2008 - it has taken me a year and a half to get this far. I have started and stopped and given up this design many times, I began to feel she was impossible to build. I wish to thank the many Flickr users who helped me along this long road with the T1, including but not limited to: gambort and nnenn who helped me chisel her nose, and bricktrix, Cale Leiphart, Brickapolis, Scotty, Jayhurst, and JamesOfJames for helping me tweak the rest.
