Unfortunately my new solution has not worked as expected, and I still have the same issues as before. I don't know why the portals aren't working in this one when they have in all my other scenarios, but it is very frustrating.

If anyone has any ideas for why the AI trains could be leaving their path as soon as they exit the portal, please let me know, it would be much appreciated.

Thank you for the continued support of this scenario, I'm sorry it has not worked as well as some of my others, but for now I've hit a dead end in possible solutions.

some probs with this one, will wait to see wether you can correct in v3, thanks for trying..........

Aggreed portals are not the best, I've stayed away from them in the past due to these exact issues. Thanks you for your reply.

Yes, I am aware of this. The same fix as V1 will work for now, and I have an idea for another solution, which will be released as V3 if it works. I aim to test this over the next few days. Sorry this one hasn't worked as well as the others - portals are a lot harder to use than it first seems!

Same problem as v1, at Guildford station the game errors with an AI train from Waterloo, unable to complete

I did warn it wasn't. I tested the first version of this scenario completely, but with the issue I found in it decided I would release this version alongside. Unfortunately, I haven't had a chance to test this one yet... I'll see about driving it tomorrow and fixing what I can.

It is not bugfree. At Guilford I derailed while I load passengers. I don't know of the rest of the journey is bugfree.
