Overtaking and passing

Trains on the same route going the same way wait or follow according to their priority numbers. Times shift automatically.

Priority numbers are 0–9, and 0 is the highest. The defaults are Ltd. Express 1, Express 2, Rapid 3, Local 5, and Out of service and Test run 8.
In “Types and priorities” on the route screen, you can change the numbers or add types.
Waiting: the train with the larger priority number waits on a passing track at a station. Trains can wait only at stations with 2 or more tracks in that direction.
Following: a train that catches up waits at stations, so it can run up to 30 m behind the train ahead.
Tap the track → “🚦 Signals” to choose automatic block, ATC or moving block. The stronger the system, the closer trains can run to the train ahead (upgrading has a construction cost).
With quad track, the line splits into express and local lines, so trains don't have to wait for each other.
Turn on “Wait/follow with other routes” to also give way to trains on other routes.

A train that can't pass an opposing train on single track gets a warning.
“Also fix single-track passing” in “Fix overlaps” can make it wait at the station before.
“Non-electrified / single” at the top of the map shows single-track sections as purple dotted lines.
