Assuming you have a CS3 you can record an event or more easily create an event which should do as you describe though I am not certain exactly what the route is. Is it a circular route or linear? It would be necessary to have three S88 contacts for the best result though you could do it with just one in he middle and timing.

Hi Geir
Yes, you must use events to create
- a stop, wait, start after a while of a specific loco and call it EVENT 1
This EVENT 1 can be triggered by a toggle track (slider operated) at one extremity of the shuttle run
Another EVENT 2 includes a stop wait and direction change (in the OTHER direction - can't be the same event)
This EVENT 2 is also triggered by a toggle track at the other end of the shuttel

If you want a stop en route you must create:
- another event (EVENT 3), activated by a toggle track (one way or both ways) to stop the loco + wait a given time.
This EVENT 3 may be triggered by more than one track if multiple stops en route are needed. Just connect the toggle tracks in parallel to start EVENT 3

Here is a very interesting video - alas in German - but clear enough for a CS3 user to get the principles (and you have english subtitles)


Of course the drawback is that you must write an EVENT 1 to EVENT 3 for each loco you want to use (because the events control a GIVEN loco
Otherwise, you must use s/w like Rocrail Seems like an overkill but also an open door to very interesting operation

I do not believe that to be strictly correct.

There are a couple of ways to work with the CS3 capabilities so you do not have to duplicate the set of events for different loco's

These include , but are not limited to ...
- building the event set with an MU proxy loco as the target. And swapping locos in/out of the MU consist.
- leveraging the loco inheritance ability of the CS3 (and CS2) events, whereby the loco in a given event is overridden by that of the calling/parent event/function that triggers it.

Played with the MU feature and it is interesting. Once you create an MU it is possible to create events with it and changing the locos in the MU does not effect the Event. Though you need to have two locos in the MU one need not be on the layout for the MU to operate. Now I need to determine which locos have the same functions in the same locations.
