Okay, here is the rest of my collected notes, part of it might have been covered already by Postal:

Letchworth:
• the divide on 2C22 needs to be DR, not DF
• 5D84 (and all associated workings) are doubled up without any rules, however this is a bit strange anyway, as 5D842 is a Class 317 (correct), while 5D841 enters as 2 x 313, which seems strange given the fact that its next working is to Peterborough
• 5D88 is described as a 313 in the pop-up timetable, while it's actually a 317. There might some other cases of this happening elsewhere.
Biggleswade:
• 1A91 and 1A97 are missing their rules to prevent double-running, as do all other trains associated with them
Hertford North
• 5B20 needs to go to the Up Sidings, as a) it's next diagrammed working 5J44 enters from there and b) being a six car train, it doesn't fit in the down sidings anyway
Welwyn Garden City
• 6L36 is scheduled to stop at Digswell Junction, probably to indicate that it gets overtaken by a few trains there. In the sim however, the stop only gets recognised once the train is past signal 617, so the best thing would probably to show both arr and dep, but have Passing time ticked
• 6G23 is scheduled to stop there, too (however in the Up direction), but as it doesn't block any other trains, and then goes into Welwyn Up Sidings, I guess this is intentional
• 2V16 needs a DR at Welwyn, not a DF
• 5K21 is unnecessary, as its next working, 2K31 is already formed as a divide off 5K27
Hornsey Rev Sidings
• 5Z21CL2 has Passing Time ticked
Harringay Park Junction
• 1M91 has the wrong traction type, either it needs to be diesel hauled, or go via Camden Road
Freight Terminal Junction
• probably rather a simulation, than a timetable problem, but all respective trains got their current location stuck here
Moorgate
• 2J72 needs to go into platform 10
King's Cross
• the biggest problem was 1C58, which is scheduled to go into P10 at 11:10, where half of it then stables until 16:17. P10 is however occupied until 11:22.
What I did was to send it to P11, which was free at the time, and then, once P10 was freed, shunt it over.
Alternatively, I think both platforms should be free between 09:36 and 09:48, so it might be possible to swap platform usage at that point, so P10 becomes free at the right time.
• 1T61 moved to 7 (conflict with 1D38)
• 3P81 moved to 7 (ditto)
• 1T63 moved to 10F (ditto)
• 1A24 moved to 6 (conflict with 5Z75 and 0P04)
• 1A37 moved to 5 (conflict with 1H06)
• 3C25 arrives a few minutes too early, but you can just hold it in the station throat until its platform becomes free
• 2Y78 and 2D86 moved to 11 (conflict with 2P41, as they need space to join)
• 1A971 needs its next working changed to 5V971
Edit:
• 5P95 should be a 12 car train, too. All other 12 car trains have the correct length, but the wrong train type.

Anyway, thanks for putting together this timetable.

That is wrong, 5B97 is a run as required train which runs Hornsey EMUD to Hertford North and returns as 5E97.

I think Chris knows the answer to this one.

I've completed this Timetable and also Peterborough 2010, so they can be chained and I'd say I've caught and changed about 97% of all the errors. I'm gonna double check these with 'Jan's' found errors

I'll probably upload it sometime this week.

Thanks for giving the Sim a severe going over. It just proves that some people find things that others Dont. As for the units . on this TT they were the ones that actuall ran on the day so a train maybe booked for a 3XX but it could / has been substituted.

As for Platforming TRUST and the WTT contradict each other unfortunately KGX PSB does not have any simplifiers at the moment.

Thanks once again
