Interlocking

Routes and route levers

Save signal locks and shunting signals as routes, let the mod work out an entry-exit route, and switch routes with a Route Lever.

A route is a named group of signal settings that you switch together: locked signals and shunting signals (Sh) held at Sh 1. Routes live in the Routes tab and can also be thrown with a mechanical Route Lever.

Saving a route

Set the signals on the map

In the Map tab, lock the signals that belong to the route and set the shunting signals you need to Sh 1.

Save

In the Routes tab press Save n set signal(s) as route and type a name, for example "Track 3 closed". Confirm with Enter.

Switch it

Select the route and press Activate or Deactivate. Active, it locks all its signals at stop together.

The list shows for each route whether it is active and how many signals it locks. Delete needs a second click.

Entry-exit route

Instead of setting every signal by hand, let the mod work it out:

Press "Entry-exit"

In the Map tab press Entry-exit.

Click the entry signal, then the exit signal

The status line guides you: first the entry signal, then the exit signal.

Name it

Type a name for the new route.

The mod looks for the shortest chain of signal sections between the two signals and locks every other signal that leads into these sections. Shunting signals along the way are set to Sh 1.

The search counts sections, not track length, and does not look at the direction the signals face. Check the result on the map before you rely on it.

Shunting signals in a route

A shunting signal (Sh 0 / Sh 1) that belongs to an active route is held at Sh 1 as long as the route is active. The route takes precedence over a setting by hand. On the map such a signal says "held at Sh 1 by a route". How shunting signals work at the track is described under Signals.

Route Lever

The Route Lever is a mechanical lever as in an old signal box: a point lever with a rope pulley between two bearing blocks, a red lever body, a bright steel handle and a catch. Each lever switches one route.

Place the lever

Several levers side by side make a lever frame.

Sneak + right-click with an empty hand. Each click links the next route, in alphabetical order. The lever tells you which route it is linked to.

Throw it

A right click throws the lever and switches the route on, another one switches it off again.

  • A thrown lever emits a redstone signal, for a lamp or a bell next to it.
  • The lever follows the route: if someone switches the route in the window or at another lever, the lever throws itself within a second.
  • Linking and throwing need the permission to operate the signal box.
Without any routes the lever says so. Create at least one route in the window first.

Routes and control areas

A desk with a control area may only switch routes whose signals all lie inside its area. For an entry-exit route, the entry and exit signal must lie in the area.
