To modernize the shunting operation, the Rhaetian Railway RhB ordered ten diesel-hydraulically powered shunting tractors from the German manufacturer Schöma. The vehicles are very similar to the 420 CT 4H, which RACO purchased from 1991. The RhB handed over the Schöma tractors between 2001 and 2004 as Tm 2/2 with track numbers 111 to 120. The first four two-axle vehicles manufactured by the manufacturer as type DFL-250 DCL are driven by a six-cylinder Cummins diesel engine KT-1150-L with an impressive 317 kW, which transmits its power to a three-speed converter transmission. In the last six tractors designated as CFL-250 DA with road numbers 115 to 120, the engine developed 324 kW. Among other things, these locomotives have a longer overall length due to a modified cooling system. The locomotives are stationed at larger train stations such as Thusis, Ilanz or Davos. With a top speed of 60 km / h, the tractors can also prove themselves in front of light freight trains and handovers in the route service and swim with them on the predominantly single-track network more easily than their predecessors, which only had a speed of 50 km / h. An eddy current brake that works almost to a standstill enables wear-free deceleration. The radio remote control, with which the predecessor locomotives 85 to 90 were still equipped, was dispensed with.
