- The stations, the signals passed, the horn points, the couplings, the consists and the timetable progress of the user's train are kept until a read adds something; the views asked for them every frame, which on a long session with many trains took the window down. A read that adds nothing no longer counts as a change. - The lights are checked against the lamps the vehicles at the ends have (written by the simulator from now on), as its driver checks them: Pc 1 without the upper headlight, with the auxiliary lamps, Pc 5 with the rear-end signals. Only while the user drives: the autopilot's lights are its own. - A train off the platform counts at both ends: its head past the stop point as well as its tail before the platform's end. - A recording without the couplings keeps the timetable for any vehicle of the user. - A signal passed at danger is ringed on the map only once it was. - In the tapes window a black box opens on a click or Enter, not when the arrow keys go over it. - The viewer's screenshot of a window not laid out saves nothing and still closes.
