Played Main Spessart Bahn today on the 05:40 service to Aschaffenburg from Gemunden Am Main. Upon going to the Dosto Cab you have TOD 1, & 2 activated with the proper function. Does anyone know what is TOD 4 used for in real life? Full gameplay of the Route will come later. If DTG does activate the TOD 4 on the Dostos Main Spessart Bahn Ruhr-Sieg Nord Hamburg-Lubeck Talent 2 SKA, Riesa-Dresden, and Rapid Transit. Locomotives HRR RRO, RSN, HMA,HHL & Riesa-Dresden. The final part is the EMU classes DB BR 423,425 DB BR 442 Talent Red and Silver and the ICE3 DB BR403 & 406 if their TOD 4 screens are activated like the Dosto. This should allow players that own all German Routes including newer HHL & Riesa-Dresden to experience an actual replication of Deutsche Bahn real-life operations in TSW 2 if the TOD 4 is activated which should display timetable and Line Speed.
