Accumulated delays?

Of course to get either of those in Simsig you'd need a special timetable. Or perhaps some *very* complicated decisions & rules within a timetable, which would also need to trigger lots of route-specific delays - an interesting exercise for the keen timetable writer, but probably not something for mere mortals to contemplate.

Are the amounts of delays influenced by the distance the service has run (e.g. Entry Time - Origin Time)?

The issue I find, especially in 'through' sims is that it becomes less about regulation and just a case of getting rid of things in the order they bell out in!

And Didcot had at one time (or still has?) a feature whereby Cross Country trains (determined by looking for Cross Country or XC and/or possibly a few other similar strings within the train/train type description) would be more likely to enter with delays.

I don't think that made it to the Loader version because the ability to do that in data didn't exist at the time.

Raises an interesting train of thought. Using Rugby as the example (and generic rather than SimSig locations) you could postulate some sort of blockage on the Trent Valley so trains diverted via Coventry. You could even just make it Up or Down train specific. Although giving complicated TTs, in principle the Decisions side of the issue would be simple. You would need to create duplicate TTs for all of the Trent Valley trains either exiting towards Coventry or entering from the Coventry direction. For the Down trains the duplicated TT would be a straight copy as far as Rugby then estimated timings towards Coventry while the Up trains would have a best guess entry time from the Coventry direction. You could leave in the scheduled times from Rugby as the train would be x minutes late at that point although I think that might cause ARS problems. Each of the duplicated TTs would be driven by one of only two decisions, Up TV > Closed or Open or Down TV > Closed or Open.

Now if you could have some sort of mechanism to activate then cancel those decisions at some random time in the sim you could then replicate the situation of an unexpected incident causing operational problems on the day until resolved . . . .

Although I understand the reasoning and understand why you won't fix it, it has the result that all local services are constantly delayed, while the long distance ones hardly give a problem. KX is a great example with this problem: All 1A** services are roughly on time arriving at KX. Even when they enter with a delay from PBRO, they have enough slack (ENG/PATH) timing to make up for it before they arrive at the terminal. While at the same time all stopping services get delay on delay on delay. At every stop they are checked for the delay chance and hence, even with a 4% chance of getting a delay a back and forth train between Hertford and Moorgate is garanteed to get some sort of delay.
I would really like it if this imbalance could be changed somehow. Maybe give the 1*** trains the same delay chance as they have now, but with more minutes late when they are deemed to be late? (a bit like the freight trains). Or maybe just separate the delay chances for 2*** trains and 1**** trains? or based on train type? then the user can decide for themselves what would be a natural balance?
