- 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.
