AI train start times Options

[dispatcher]

This question is for the AI train specialists.

When I scheduled all my AI trains, I used the longest train run possible which was approximately 5 hours in duration. I scheduled an AI train approximately every hour leaving from the furthest point and so that I would have the first meet soon after departing with the player train at 10:00 am, I started the first AI train 4 1/2 hours before the player train departed thereby having a meet early on. Everything was just fine. My question is: if I start a new activity from half way across the whole route and at the same time as the longest player train did, say 10:00 a.m., will the AI trains start at the new 4 1/2 hours prior to the player train or stick to the original player train times? For example, if I had an AI train starting at 10:30 in the original train, will that same AI train start at 10:30 in the new activity?
