AJS Turntable not working [solved]

I'm trying to set up the "AJS Turntable" & "AJS Turntable stub" in TRS 2019. This is my first attempt and I'm probably chancing my luck doing it in the TRS2019 Beta.

The problem is the locos stop short of the turntable rather than stopping on it, when told to go to a trackmark on the opposite site of the turntable.

Placing a signal before the turntable shows the problem clearly - a red light:

I've checked and ensured the stub track is aligned and snaps to the turntable segment which it does, however the circles do not turn yellow.

I'm following the instructions as per
http://www.trains.0catch.com/Installing a Turntable and Operating it Under AI Control.pdf

I'm not sure if this is a bug or something with AJS turntable that needs to be re-edited to work with TRS2019, but I've logged a bug anyway.

A bit of progress, apparently signals are to be used like magic sparkles and sprinkled liberally around. I can now get the AI driver onto the turntable, but once on he sees red lights and cannot get off.

Place a signal at each end of the turntable on the moving part but face out from the middle. In other words rotate the two signals you have on the turntable. Don't put signals to come off the turntable. It would seem that a signal cannot see across the stub part of a turntable to another signal that is on the other side. Most turntables are operated under the control of a railway worker so don't need signals.

After an awful lot of tinkering, it works! I had inserted a junction by accident off screen. Seems the trick is to have two signals on the middle turntable itself (or invisible signals)

Thanks, I'm going to rework this tomorrow. After I've had some sleep!

Just a quick update with a slightly improved (or different) version, moving the two turntable track marks onto the rotating platform itself - along with the invisible signals pointed inwards.

The AI driver will drive on and off both lines repeatedly with a repeating schedule e.g.

drive to turntable side 1
drive to turntable side 2
moveturntable to stop 11
drive to trackmark 275 (wanted to call this 'turntable entry 2' but for some reason that name got corrupt & could not be used!)
drive to turntable side 1
drive to turntable side 2
moveturntable to stop 12
drive to turntable entry 1
repeat

The one problem I found with two TM's on the table was knowing which one was at each end when used several times. I would place a single TM opposite to the stop 0 (TS 2). So in your set up I would drive to entry 1
move turntable to stop 12
drive to TS 2
move turntable to stop 11
drive to TM 275
If other trains have used the table it might be in the wrong position.
move turntable to stop 11
drive to TS 2
Move turntable to stop 12
drive via entry 1
You can use the move turntable command even if the table is already at the correct position as it will just delete the command and continue with the next part.
With the invisible signal pointing inwards you could find that some trains might not reach the TM's radius. Mine face outwards so large trains can move close to a small radius (5m) TM.
