Train waiting station and signaling

[JustSmile]

Consider the following waiting area: https://i.imgur.com/erK6os1.png

Is it possible for two trains to emerge from their waiting bays simultaneously (and collide) once the way is clear? Or are the signals done fine?

The signals are fine.
In fact collisions without manually driven trains are quite hard to get when you have signals.

If you want a bit more details on how the trains will work, the trains will ask their chain signal if they can go, only one of the signals will be able to reserve the block for its train and the others will be forced to wait until the previous train went beyond the block that is after the normal signal you have on the top right (when that signal turns green because no train is in the block after it).

Cheers, that clears up a lot.

I have never had an automatic train hit another automatic train on a signaled section of track.
You parking system looks similar to the style I use too so it should work.

You can save a little space by having your parking diagonal.

shouldn't the signals be reversed? the chain before will force the trains to recalculate which lane is open.

never mind, looking at the wrong side of the track. xD

For stackers there are a few valid ways to signal them, this is one of them, without a more global view of the stacker and station after it we can't say if that's the best one or not.

Chain signals go on the exit so only 1 train can exit at a time.
Regular signals go on the entrance to the parking spot.

We might need to look at the entrance to the waiting area to make sure that part is signaled correctly.

Every parking spot's got a regular signal at the entrance, yup.

Rail signals do exactly that as well, otherwise they'd be pretty useless.

This way : Trains won't start to move until the next block behind the exit is free. They'll all wait neatly in their lanes.

Regular signals on every lane exit : First train to find the exit block empty moves into it, waiting right at the exit, every other waits in the lane.

The only difference for this kind of exit is in how efficient vs. how tidy looking it's gonna be. Unless it splits up into different stations or lines for different trains after the stacker, that is. Then you ofc. dont want to block the exit and need chain signals up until the points where it can't jam.

I see no problems with your waiting area.

In this particular case the waiting area leads out to 4 different unloading stations so yes, chain signals are a necessity.

If it leads to multiple places then the normal signal is probably not right in that place, you most likely want chain signals all the way to each station, only having a normal signal covering each individual station after the rail branches off from the common rail.
That way you can be sure that trains only depart from the sacker if they have a station available to them.
