Hi all,

I have just started this sim and have a copy of the sectional appendix open as well to try and keep track of the line speeds. I have noticed that in the sim, the Down Fast runs through Rugeley Trent Valley Platform 2, whereas the Down Slow runs adjacent to it away from the platform. The sectional appendix (page 7) seems to suggest they are, in reality, the other way around. Am I misreading it or is there a (small) bug with the labels in the sim? Other than tilting trains, the line speeds for the two lines are identical anyway so I suppose it does not matter really.

The Stafford simulation is based on the old Trent Valley layout. Since then, slow lines between Tamworth and Armitage Jn were added, so I'm guessing the lines at Rugeley changed identity at the same time.

The sim is replicating the layout before all of the Trent Valley upgrading. Is the SA showing something more recent?

Thanks for the replies! I must admit, I completely missed the item on the very page I quoted that says "Armitage Junction (former site of)" near the top of the page. Unfortunately for me, it is at that point that the appendix is split between northern and southern halves, and I didn’t bother to check the other half! The appendix dates from earlier this year and appears to show an upgrade of the lines between Tamworth and Rugeley Trent Valley when compared to the sim.

Thanks again guys!

The changeover happened with implementation of the TV4 (Trent Valley 4-tracking) scheme. The line is now 4-track throughout from Nuneaton through Tamworth & Lichfield as far as Colwich. I imagine the original configuration (down fast - down slow - up fast - up slow) was chosen to give trains via Stafford the fastest possible run at Colwich. I believe, since TV4, all trains running down the main are forced to slow for the fast - slow (formerly slow - fast) crossover at Colwich (a 50mph turnout in the 1980 Sectional Appendix and I don't think there's been any significant alteration since). So much for joined up thinking...

Linespeed from the Down Trent Valley Fast at Colwich Jn is now 65 towards Stafford, 45 towards Hixon (Stoke). comparatively the Down Trent Valley Slow is faster at 90 throughout the Colwich area, however there is no conveniently fast place to take the DTVS - there's a 50mph crossover at Cuborough about 10 miles up the line, but you don't gain anything by using it and could potentially end up behind a 1Uxx calling at Rugeley.

Interestingly, looking at the sectional appendix, linespeed is the same on the DTVF and DTVS between Tamworth and Colwich - with both down lines being signed for 110/EPS125, so the concept of Fast/Slow is relatively moot.

As an aside, a modern timetable should run reasonably well on the old layout, although you will find Pendolinos will lose 1-2 minutes. For very modern timetables with 110mph London Midland services the loss may be slightly more, but it won't have a massive impact on train running.

Its obvious that sim was built before the new system, is it possible for the sim to be updated to have all 4 line from Colwich Jn through to Nuneaton? or maybe make this a new one and keep the old one, for instanace like Carlisle it has the 1980s Panel and the 2000s Panel.

I have a rather strong suspicion it would be on the banned list; someone might like to confirm. Even if it is open to simulate, the developer would need access to the data for the modern layout and that's no small thing. (Of course if that were the case the modern era might be under way as we speak but IF that were so I wouldn't expect to hear until it was released.)

Probably not: When the line was upgraded, control went to Rugby SCC, which is affected by the conflict of interest and therefore on the cannot be simulated list.

Thanks for replying, just read through and clearly understand. Just have to see what could be done, but its on the Banned list then not to worry. Current Version im happy with.

Interesting. I'd imagine this would benefit slower LM trains but also those VT trains which call at Lichfield and Tamworth. They can still use the 'slow' lines at full speed without loosing time crossing over twice.

It's also debatable how much a 2014 timetable would cope on the sim layout - I've certainly thought about writing a timetable for it.

A current WTT is good fun for regulating on the 'pre TV4' layout.

But then again, my idea of fun is complete carnage! :doh
