Could I just use chain signals everywhere?

[Dave64738]

So is there any reason still to use basic signals? Could chain signals be used throughout?
Or is there some logic that needs basic signals to be in place so that it will bottom out?

[DaveMcW]

Chain signals do not divide the railroad into blocks, they just extend the block they are chained to. You must have more blocks than trains for the railroad to function.

So the general rules are:
- Chain signals before and inside intersections
- As many normal signals as possible on straight tracks

Examples:
[s] - signal
[cs] - chain signal

Example 1:

Code: Select all

Train ---- [s] ---- Block 1 ---- [s] ---- Block 2 ---- [s] ---- Block 3 ---- [s] ---- Block 4 ----

In this situation Train can enter Block 1 when Block 1 is empty.

Example 2:

Code: Select all

Train ---- [cs] ---- Block 1 ---- [s] ---- Block 2 ---- [s] ---- Block 3 ---- [s] ---- Block 4 ----

In this situation Train can enter Block 1 when Block 2 is empty. It's mean that Train can leave Block 1 without stopping.

Example 3:

Code: Select all

Train ---- [cs] ---- Block 1 ---- [cs] ---- Block 2 ---- [cs] ---- Block 3 ---- [s] ---- Block 4 ----

In this situation Train can enter Block 1 when Block 3 is empty. It's mean that Train can go through and leave Block 3 without stopping.

So more chains signals menat more block have to be empty to allow train go.
