Ai Run Round Problem

Hi all,

Please can somebody assist me with a scenario that I´m creating that involves an ai station run round. It´s on the London - Brighton line and it´s at Redhill.

What I am trying to achieve is a class 47 inter regional service arrives into the bay platform at Redhill from the Guildford line. I´m successful in that I get the train there, the loco uncouples and then draws forward, reverses and then travels down an adjacent line past the stock, stops and then draws forward to back onto it´s rake of carriages again but that´s when I hit my issue because the 47 then proceeds to plough into the back of the train and the scenario ends with an ai collision.

I´m familiar with the drop of instructions and the pick up instructions but I can´t get this one to set correctly at all. Can anybody help me out?

Many thanks in advance,

Simon

Due to a game limitation, for AI traffic it only remembers where stock was at the start of a scenario, it doesn't update its position at all. That's why it is colliding with it.

Does your run round happen in view of the scenario player, or is it an operational thing you're doing away from the cameras so to speak?

Hi Deltic.

Thanks for coming back. The idea is that it happens on camera but I guess it wouldn´t matter if it was off camera because I can work round it, I just thought it would add something to the visual feast :-)

Yes, believe me, we have all wanted to see this in a scenario but sadly it just won't work.

If you can do it away from camera the using portals is a good idea.

Some while ago, I couldn't even get a loco to run round to the other end of the sidings and pick up a different consist!

Try using a scenario specific stopping point/marker--the loco might push the coaches a bit hard, but it should be going slow enough not to cause a derailment.

I tried that and had no joy with it.

Yeah, getting the marker in the right place is as fiddly as hell.... best I've managed is to have a 47 pull into Redhill Platform 1, un-couple, pull forward and reverse past the coaches, then move back to gently nudge the consist. I can't get it to actually couple using either the "Add to...." or "Marshall" instructions. I suppose it does 'look the part' if nothing else....

If anybody has nowt better to do (you sad, sad so-and-sos.... :wink: ) what I've been messing about with is at https://www.dropbox.com/s/qmpffwvnc40v1 ... d.zip?dl=0

You will need to run it past RW Tools if you want to join in the party games though; my Kuju MkIIs live in a different location to anybody else's.

I did a similar thing to simulate a loco swap of a Euston - Blackpool at Preston.

I am sooooooo tempted to download the file purely to put my Kuju MkIIs there and thus make your post a lie!!!

:D

Very nice...is part 2 on the Workshop?

If nothing else we've confirmed that Matthew's post that:

still holds true, and to do what Simon wants can't be done at the present time, only simulated to a certain degree.
