In the routes editor you can manage the pre-set routes of the railway:

A route in the meaning of SharpMrc leads directly from one block to another, i.e. there must not be any other block between the start and destination block of a route. It can be "Reversible", indicating that it can also be used in the opposite direction (destination block -> start block).

"Direction" indicates the direction from the start block to the destination block. You can make a route change the orientation of the locomotive from the start block to the destination block. Consider the following example layout:

/----------------B---------------------------C------
|
|
\-----------A---------

A, B, C are blocks. In this situation you should make the route A -> B change the orientation and set its direction to "Left". Then a locomotive driving forward in A to the left will continue to drive forward in B, but now to the right. Then you can set the route B -> C to direction "Right", but the locomotive will maintain its actual driving direction.

In the right list you enter the switch commands for each route that must be issued so that trains can actually get from the start block to the destination block or vice versa. SharpMrc will perform automatic interlocking based on those commands, i.e. a route that uses a switch that has already been set by another active route will not be allowed to activate.
