The T.11 (another designation: OKi1 or BR74 or Baureihe 74.0-3) is a series of steam locomotives (steam locomotives) that were produced in the period 1903-1910 by several German companies, mainly by the Henschel plant. The length of a single locomotive was 11.19 meters, and the service weight - 62.3 tons. The diameter of the driving wheels was 1500 mm, and the locomotive had 1'C n2t axles. A total of 471 locomotives of this type were built.

The T.11 series steam locomotives were custom-built by German railways and were dedicated to the Berlin suburban railway before it was fully electrified. Hence, the locomotive was adapted to rather small mileages, it did not take much coal or water in the tender. However, an efficient twin steam engine was used as the drive, which was similar to the engines mounted on OKi2 steam locomotives. After 1918, about 50 locomotives of this type were taken over by PKP, which changed their designations to OKi1. After World War II, some of these locomotives returned to the PKP rolling stock.
