Persuading an AI Driver to couple

I

I have a situation where an AI controlled loco has pulled it's consist into a terminus, and has uncoupled from the consist.

I then have a 2nd loco drive into the terminus with a drive to trackmark command followed by a couple command. This loco will only go so far towards the consist, when it stops and a message appears 'waiting for access to track'.

How can I get the loco to couple?

The annoying thing is that I've done this successfully in the past with TRS2004. I'm now using TRS2006 and I've forgotten how I used to do it!

Any help will be very much appreciated,

Ian
 
Hello Ian,

I have had limited success with rule: "couple to trackmark" Only limited I fear due to my doing something wrong (as usual).
There is another rule: "couple infront/behind signal". I have had success with this. There is probably a radius for signal as rule does not operate (for me!) all the time.

Assistance for both of us appreciated eh!

ess1,

do you have the kuid number for that rule?

Referring back to Ian's post, do you have the first locomotive uncouple and move away from the train, even if the coaches prevent it being properly released? This might be the cause. I always ensure that the train stops a little way from the end of the platform, so an engine can creep a little nearer the buffer.

For the second engine, I use the driver command "couple at trackmark" - is this what you mean, ess? I've had a good deal of success with this, providing the second engine does not have to cross any signals. Again, there is a radius [sp?] on the trackmark, but it does seem quite generous.

That said, I have come across this problem before elsewhere, and I never found out what the issue was. I realigned the track a bit and it cured itself. Probably a poor spline point in my case.

Hope it helps,
BidMod.
 
couple at Trackmark Command

I've managed to download the Couple at Trackmark kuid (2_57145.81100_1cdp), but can someone tell me where the file should be placed within TRS2006.

I know CMP is supposed to install it automatically, but I have not been able to make it work, despite the first class ticket (which has now expired!)

had a similar problem myself. try coupling your second engine, then use the de-couple command to release the original engine. unless you can move your original engine into a separate section of track ie past a signal ai's don't like going into the same section of track because they can 'see' two consists in the next section.
 
Hello DAP,

Kuid I have for Couple Ahead, Couple to Vehicle, Couple to Vehicle Near Signal
and Couple to Vehicle Facing Trackmark:-
2:131986:1015:1, 131986:1003, 1004 & 1002.

Let us know how you get on please. Any little helps.
 
Yes, but where do they go?

Thanks for the advice re kuids.

I repeat my last query:-

I have the kuids on my computer, but they are not installed within TRS2006.
Can someone please tell me where to install them manually within the program.

Thanks in advance.

Ian
 
Thanks William, but no, it doesn't work despite repeated attempts.

I know how to install kuids manually in TRS2004, but I can't find where they should go in TRS2006!

Ian
 
Installing assets manually is not possible with TRS2006, what you need to do is open CMP and double click on the .cdp file, then it should show up in CMP and all you need do is select the assets and press Ctrl+M to commit them. Otherwise they will not show up in Trainz.

ess1,

I found all but Couple Ahead, but I think the others will do what I want. Thanks much for your help.

I have downloaded and installed these commands successfully but am having a problem making them work.

The scenerio - I have gathered a string of cars from various industries that are destined for a foreign road. I drop them off at the interchange track and spot them so they are just shy of the Track Mark. I then go on with other switching duties while a foreign loco appears, picks up the cars and leaves.

I have programmed the foreign loco as follows:

Drive to Track Mark
Couple at Track Mark
Drive to Portal

The foreign loco arrives to couple up to this string of cars and take them away. The locomotive approaches the string and stops. Then nothing happens. It just sets there. How can I get it to couple up and leave?

Dap
 
Try without the "drive to trackmark" command, as this command is actually included in the "couple at trackmark" command.

Interesting discussion.

I am unable to couple to trackmark at a terminus. Loco just travels until near the carriage then stops. I presume the AI "sees" that line is occupied by the loco that brought the consist into the terminus.

I schedule as follows: drive to station/unload/ uncouple/drive to trackmark xx (which is near station buffer). This triggers the shunting loco: wait for trigger xxx/couple at trackmark xx (same TM as arriving loco).

This may be the problem. Perhaps I should have further TM i.e, TM 1 for loco to drive to after uncoupling and TM 2 for "couple at TM2".

Not sure if this would work 'tho due to space - TMs too close and trigger interfering. Not much space between arriving loco and buffer.

Anyone any ideas on this or, indeed, on the whole couple at rules?

Cars in AI's way.

I believe the AI on the second loco sees this: consist - TM - loco. but this is what the AI is looking for: TM - consist. This what you will need: TM1 - consist - TM2 - loco 1. AI's also won't couple to a consist if there is not enough room for the consist to roll after coupling.
