Suggestion: routing through depots

[smurfix]

I'd like to have an option for YAPF to route through back-to-back depots, with an appropriate penalty of course.

Rationale: I want to build an overflow depot and don't have a heap of free space.

I want to use realistic braking, so no block signals and thus no way to use the standard "dead-end track" trick, AFAIK.

I have been unable to come up with a design that works, much less one that doesn't use some strange track layout. Adding a waypoint and conditional orders is a no-brainer, but frankly my trains' orders are complicated enough already and IMHO they should focus on where to go and what to load, not how to get there (or not).

A back-to-back depot along the approach to a station would be an easy fix for this problem.

Seconded, much more useful than anything I've suggested.
