The demanding climatic and geographical conditions under which railways operated in Russia led to early trials with diesel power, but many attempts also were made to improve the performance of the steam locomotive. Pictured here is undoubtedly the most extreme example, the 1-E-1 TPT1-1, completed at Kolomna in 1939, works number 8000, and built to the country's predominant gauge of 5 ft (1524 mm). Fuel was anthracite, which fired not only the steam boiler, but also a gas generator in the condenser equipped tender, the opposed cylinders operating on a dual steam-gas cycle. Enormously complex, it did move itself, but at speeds above 30 km/h was excessively prone to failure, pre-ignition on the gas side being a seemingly intractable problem. The expenditure of much effort might have brought improvement, but assuredly it could never have been made a viable traction unit.
