Runaround Problem

[Ian_Coleman]

I've been using the Runaround command int TRS2004 for a very long time with no problems.

Suddeny, I do have a problem! In the course of creating a new layout, AI drivers arriving at a particular station are required to execute a runaround command, and this is what is happening:-

The loco has completed the early stages of the command, and has uncoupled, moved forward through the points ahead, then reversed direction onto a parallel track, until it passes the junction which will bring it back to the rear of the consist in order to couple to it.

At this stage of the procedure the loco stops, and I get a message that the driver is awaiting clearance of the track ahead!

Every time I have used this command in the past, the loco has completed the runaround, and coupled with the consist with no problem and no message!
If anyone has an inkling of what may be happening here I would be most grateful!

Make sure the last juction is defaulted to the back of the train. Carl

Forget my last post. I ran a few tests to see if I could get it to do what you said is happening. The only way I got it to fail is if there was another turn out between the one used for the turnaround and the back of the train. This was in 2009 compatability mode, Carl

In my previous experience, the loco would always go past the first available junction to return to the consist, and always look for a second junction!

If I ever add a run around loop to a route I always reduce the trigger radius of the points in the loop to 5 which prevents the engine moving too far away from the train

Not sure about 2004 but in 2009 I would suspect something to do with the signalling. You could try placing a signal just in rear of the stock and see what happens.

I've never found it necessary to use triggers in conjunction with the runaround command!

Nope, neither do I. What I do is reduce the 'trigger radius' of the point which means that the engine doesn't move so far away from it before the blades are able to switch to the alternate track.

The 'trigger' in this statement has nothing to do with the green triggers that are available for placing on tracks.

How do you reduce the trigger radius of a point? I've been trying to do that since reading your suggestion, but I can't see how you would do that!

Hi Ian,

Bring out your rail tab, click on the trackmark and trigger icon, click on advanced, remove the 20.00 which will be in the small window and type in 5.00, click on the points, click on ok.

Cheers,

Hi Ian,

Bill is exactly right with his advice. I find that reducing the trigger radius of points in yards and station areas really helps with AI shunting and movements. By using the method described its also possible to reduce the trigger radius of a buffer stop which allows the engine to travel closer to it before stopping
