Interlocking

Track map

What the live track diagram shows - occupancy, signals, trains, delays, level crossings, kilometre stones and signal telephones - and what a click on it does.

The Map tab shows the rail network of the dimension you are in, from above. The same picture appears on the track map displays, desks and consoles.

Scroll to zoom, drag with the right mouse button to move. Hover over a signal or a train to see what a click would do.

A legend of the lines sits at the side.

Delays

A train counts as delayed from 30 seconds, as CRN reports it. On the map it gets a red border and its delay next to its name; in the Lines tab the delay stands behind the train.

Level crossings

Level crossings appear as a crossbuck. Only crossings whose control box is loaded are shown. An on-call crossing that is waiting for release can be released by a click on the map, see Level crossings.

Kilometre stones

A Kilometre Stone lettered with Create's wrench (for example 12,4: 12 on top, 4 below) appears on the map with its value, also where the area is not loaded. Station, crossing and train labels go first where space is tight.

Signal telephones

Each Signal Telephone shows as a small white box. While it rings or a call is running, it flashes yellow and carries its name, for example "F P7". The telephone itself belongs to the train radio, see Train radio.
