turntable again grrr.

[Ghost42]

Before I abandon the idea I thought I would ask....
Copying a working prototype - surely this will work also.
Consist feeds the power station, parks up, decouples, loco spins round on the turntable, loops around to the rear, stops, reversing light appears.
Great it's going to couple!
But it changes direction and drives to the the opposite end of the route, (8 miles) loops and returns to couple to the consist.
All is well apart from the loco is now about face and the power station is out of fuel.
Any ideas? If not I'll enlarge the island and put in a loop.

I have had this happen with locos that have a light on the tender. Try a different loco.

Thanks for the input, I have tried two further locos but sadly the same thing results, reversing light flashes then changes direction

Success, had to force-feed it with three wait-trackmark pairs. something amiss with the Couple command.

What commands are you using after the train leaves the turntable?

The success was a flash in the pan, happened just once.

Report is 'awaiting further instructions'.
Previous command was rotate turntable. The loco trots through two junctions before reversing.
Thought of deleting the signals but the main route requires them, seems once you use one they must be applied throughout the route or the dreaded 'unsignalled' reports appear.
The parallel setup carries on flawlessly, identical setup

Have you tried couple to vehicle near signal. The other thing is to delete the signal before the diverge and place it at the end of the loop before it enters the single section of track. That signal if it stopped an incoming train would block all the tracks in and out.

Thanks, I'll add that to the circuit. Had an idea to use two different turntables (a walking the dog moment), solves many programming puzzles

All up and running, let it run for 30 miles, no glitches.
Strange stuff, uncouple would only happen if it approached the trackmark pointed end first, position of signal when coming out of the bypass is critical, loco likes to drive over two switches before it reverses to couple.
Got around that by adding a spur for the turntable-returning loco to sit on.
