Hi,

I am setting up a shuttle train as per the updated CS manual, but I cannot make it work.

What happens is that the setup as per para 3.4.1 (pg. 34) is ok, but things go wrong in para 3.4.2 at 2nd dot: Place the train at station 1 or run the train to this station. At this point the loco controller has already lost control of the selected loco! Nothing happens on the speedgraph when turning the red knob and hence no movement of the loco. The small shuttle sign is not appearing above the speed graph.

I can then cancel the shuttle train by the command End shuttle train (and delete the s88 setup), but the loco controller does not regain contol of the loco. This to happen requires a shut down of the CS first.

My test setup is very simple, a short straight C-track with two circuit tracks (#24994) as braking points b) and d) wired to port 1 and 2 of a Viessmann 5217 s88 decoder.

I have no experience what so ever with the s88 bus and capabilities, so I am quite blank on this problem. I cannot see what else I can do.

One thing that puzzles me is what is described by Bigdaddy in the quote below. I cannot find this note in my manual <s>and I am not sure if the ground of a Viessmann decoder is the two ports marked capital t (T). Unfortunately the lay-in paper does not tell much.</s>
Edited: These two T terminals are in fact ground (brown). I connected one to track ground, but this makes no difference - same poor result! [:(]

Help on this one very much appreciated. Thank you.

Benny,
I cannot fully understand your description, Do you have an s88 issue or a throttle issue

I have had (related) issues that smell of a software bug in the throttle&lt;&gt;Loco ownership/reservation area. (not just the shuttle function)

Can you please report
- CS code level
- How many Locos are defined
- Do you have multi ownership enabled
- How many shuttles have you defined
- Do you have any of the s88 inputs, that you use for shuttle stops, also being used to set routes.

And just to check, ignoring the shuttle operation, does the appropriate s88 box on the CS display indicate its state correctly (filled in) when you jumper its input to the T?

Personally I would not invest time in the shuttle function as provided, it is too restricting

Thank you Peter. You directed me to the solution. The key point in you reply was the 3rd issue about ownership.
I gave the ownership away without allowing multi ownership.
Once I checked the "enable transfer of control to other ops" it works. The loco runs repeatedly forward/backward as it is supposed to do.

Hi Peter.

I see what you mean, so for the benefit of other members that might be "struggling" with this I show the screen. I simply parked the loco on the switch connected to port 7 while taking the picture. Port numbers are counted from right to left.

Also make a worthwhile note in your updated CS manual under 3.4.1 Setting up Shuttle Routes on pg. 34:
Allow multi operators' control - refer to 6.1 Other settings (pg. 39) righthand col. It will not work without this setting!
