An autumn weekday based on a random day at Liverpool Lime Street and the surrounding areas.
Due to the complex of changes within Lime Street Approach Station, platform clashes are likely due to no Platform 10. Re-sginalling of the whole area excluding Ditton East Jn/Arpley Jn freight only lines makes things a little tricky, one area missing is Widnes Transport Tech Alstom although two trains were booked to use it was deemed unrealistic to send them via Foundry Ln so these have been removed.

Various freight operations would benefit from adjustments to the stopping position.

For example, run-round operations at Garston should have the light engine stop at the Near end of Church Road and Speke 63/68 locations, to reduce the dead time spent travelling back and forth while reversing direction. Quite a few 0Fxx and 0Mxx services need this specific adjustment.

Also a long train entering Ditton O'Connors via the Reception Sidings, such as 4M89, should stop at the Near end of the Reception Sidings. Without this, it will stop with the leading end at the far end of the siding but refuse to proceed towards the headshunt, which is necessary to bring the tail of the train clear of the main line and the points giving access to O'Connors.

Many thanks for this, these are all sorted for the next version including a missing rule for one shunt move.

One more problem cropped up: 6X43 goes into Garston Car Compound in two parts. However, after running the loco around and dropping what was the front half of the train, SimSig thinks the loco is attached to the front half, not the rear half that actually has a path to the compound. Since that also leaves the "unpowered" half of the train hanging over the end of the Down Goods (ironically the only vehicle foul is the locomotive), the job is effectively stopped for all Garston locations.



My suggestion here is to position the train at Far-Exact end of Garston Goods Lines, then have the unpowered stock perform the split into two halves while the loco run-round is in progress. This fits naturally with the shunter walking back along the train after uncoupling the loco, and splitting the stock on the way to the subsequent coupling operation.

Many thanks for this, I have fixed this issue for the next version. Unknown why I left this must of been side tracked at time I was sorting them. Also I have retimed 6X41 to it's actual timings of around 5pm arrival.

The Birmingham-Liverpool WMR trains all have 'passing' ticked on their timetable for Runcorn and Liverpool South Parkway.

Not sure why?

These are fixed in the next version of the timetable which I'm nearly done on testing.

This might not be a timetable question.

I have just platformed a Birmingham-Liverpool (2x class 350s) which in the F2 list is 264m. It just went into Platform 9 with no argument (and no overhang) which in the description box above the station display says 246m.

What magic is going on in Lime Street?

I'm glad you spotted this as I didn't!, 2x 350s are 164m in length, typo error when doing the train lists, now solved.

This might be a difference between usable platform length as opposed to length from buffers to end of starter signal berth track circuit. Does the train correctly report stopping at Lime Street and change to its next working?

As noted above, it seems the train is actually shorter than its description claims. Since P9 (before the rebuild) could reliably accommodate an 11-car Pendolino set, it should logically have no difficulty with an 8-car Desiro.

350s are 20ish metre coaches

I rather suspect 264 is a typo in the description for 164

I was thinking 264m seemed a bit excessive.

However, it does fit behind the signal on platform 9, and picks up its next working, despite being too long. I guess it overhangs the platform but not the signal.

2x350s are 164m in length, was a typo error when doing the train lists, this has now solved in the next version of the timetable due to be released next week.

I tried to reply to different posts and none of it worked properly...

I understood your point on the length - it also took me quite a while to notice it was a bit high.

I was commenting to somebody else that it wasn't just the description, but the actual length. My query was on how the train - which thinks it is that long - could fit in platform 9.
