A question for our District Line T/Os

As always with LUL WTT's the year is 2012. What you might not know from that is that there were line notices in force for that particular timetable. Speed restrictions might have been imposed because of engineering works overunning at weekends and so on. 5 minutes might also mean a long dwell at Acton Town to allow late trains to catch up with the WTT if there are delays elsewhere. I'm not a scenario builder, so I can't offer a workaround other than invent an issue that will force your train to take 5 minutes.

I've created WTT-based scenarios with no problem, and maybe a little adjustment to fix issues caused by TS pathing and AI behavior. It's important to note that the 5 mins from ECM to ACT is a max duration time, such that the overall timetable can be kept to. There will be times you can run it faster, while keeping to speed limits. There will be times you're held at the outer home 'cos the pfm is occupied by an annoying Picc train, or other minor delay.Any train out of it's usual pattern and times will have some knock-on effect.
This doesn't stop the scenario working, nor the train departing each station to time - assuming you drive within the allotted times. Your train will be held to stated departure time if you are early into a station, so you should always depart on time even if early arriving. I believe dwell time is also factored into the 5 mins, and given ACT has an adjacent Picc pfm, it's possible that allows for train interchange also.
When creating WTT scenarios I simply put the scheduled departure time in the timetable, and/or adjust the train's percentage number to tweak the times to be correct. If the percentage is too low you will tend to have longer dwell times. And weaving other services around the player train can be problematic, and always has been. Take a look at the 2nd half scenario I put together, and you'll see I used AI trains multiple times so they appeared where/when I wanted and unless you noted the car numbers you'd not now it was the same AI train.
If I'm missing your point, or you'd like to discuss further with the team please keep replying. This is a great topic for discussion.

The section EB from ECM to ACT can fool TS into pathing through the depot, as it's a shorter path. However I put in a destination marker on the "Slow Ealing" road EB that can be used as a "via" marker and force pathing down the correct road. As I wrote elsewhere:

Every platform and siding has a marker that can be referenced in scenarios.

Additionally there are several destination markers placed for things like "limits of shunt" that may be needed as a destination as part of a scenario, such as reversing wrong-road into Lillie at West Ken. There are also specific destination markers that when used will force correct pathing in some locations. Example - just using ECM EB and the Acton Town EB Slow pfm will cause pathing through ECMDT as the path is shorter! There is a destination marker on the EB Slow road that if placed as a "go via" between ECM and ACT will cause correct pathing via the "slow Ealing" road.

Hope this helps!

Is there any chance you could modify the bin files or what ever needs to be modified for the speed on the D78Stock and the BatteryLoco as I'm sure you're aware the D78 has a maximum speed of 60 MPH rather than 45 MPH and the BatteryLoco has a maximum speed of 29 MPH rather than 45 MPH. I do love the product but I would like it even more if the D78 and BatteryLoco could have more realistic speeds if possible please.
