Since the 4 track went live the system has been much better behaved. The problem is it doesn't understand the causal relationship of a delay

If a fast train is trapped behind a slow train, the fast train is still projected based on the fast timing when in fact it should inherit the journey time of the train ahead until such point that train is no longer in the way. So if a train to Cork gets stuck behind a Limerick stopping train once it catches up it will be projected to arrive Limerick Junction about 7 minutes after the Limerick train and will inherit its normal point to point times from there. Thats simple now throw in passing loops, single track, four track and turnbacks and its not simple

Put it this way to get a system that can do that properly costs a fortune and in many cases major vendors have tried and failed to get it to work. You need to get into artificial intelligence.

I could put a R&D team together for this sort of thing but its going to cost to be done correctly
