Runaround track
Work in progress: This section is still a work in progress — content is being added and revised continuously.
What is checked? Stations with industry spurs but no runaround facility (no track pair connected at both ends).
Why does it matter? Without a runaround the locomotive can never get to the other side of its cars — spurs facing the “wrong” way can then only be worked by pushing over the main. The operations planners’ rule of thumb: wherever switching happens, provide a train-length runaround, as close to the station as possible.
How to fix it: Connect the one-ended siding at its second end — or pick “Build runaround” on the finding: in parallel-track mode, “Turnout left” and “Turnout right” connect the new track at both ends.
Numbers & defaults: notice level; checked per detected station group.
