Infrastructure · Overlay
Read the line beneath the train.
Line speed, electrification and gauge on one overlay — so a lineside guide can tell you what runs, how fast and what powers it, before you set out.
What the overlay shows
Three readings, one grammar.
Line speed
Permitted line speed bands, drawn as the line itself — no second symbol layer.

Electrification
Overhead AC, third rail or diesel, with the supply noted in the line popup.

Gauge

States
Truthful when data is thin.
