I would love to see an updated version of Feltham with platform extensions and a 2018 timetable.

It requires information for the developers and a free developer but never say never.

It's come up before - SimSig doesn't have a concept of "platforms" - and as far as I can see there weren't any signalling changes associated with the platform extensions.

What aspects of a current 2018 timetable don't work on the layout provided in sim?

That's not entirely true. Originally there were stop markers in the direction of travel but there are now near end stopping points too.

That I would be interested to know.

10 car train wouldn't fit in the majority of platforms due to there being no 10 car trains back in the day.

Yes, but what were the signalling changes? In many cases platforms can be lengthened without affecting the signalling - or the simulation.

Yes, but what actually doesn't work? As I said there were no signalling changes that I'm aware of - save a different layout to the SR platforms at Reading with 3x 12 instead of 2x 8 car platforms - and very few, if any, of the Reading trains run as 10 cars in my experience.

Lots of platforms were extended yes, but the signals weren't moved that I can see.

The majority of Reading trains are 10 car 458's

Sorry to hijack the thread slightly, but does simsig penalise us in anyway for signalling a train into a platform that is too short? There are some exceptions like long Eaton where trains are booked to use shorter platforms. If not I don't see any issue

The only possible difference a SimSig signaller might see would be if the longer trains don't clear the previous track section while stopped. Provided the longer trains fit within the track sections as written into the sim, the signaller would see no difference at all while running the sim. Possibly someone in the know could tell us whether any TCs were changed during the platform lengthening process. If not, then the sim would need no updating and what you want is someone willing to put a 2018 TT together rather than the developer having to re-write the sim. Presumably some other public-spirited citizen would also need to update the sim manual on the Wiki with 2018 and previous details if that shows any platform lengths.

There were a few changes at wokingham.
New main aspect signal on the up end of the down platform so you can terminate trains on platform 2 and start them back in the oppsite direction.
One interesting feature also is the signaller has control of the traffic lights around the level crossing area.
From what I know, the signaller has a lock/release button so when engaged the traffic lights will return to red protecting the crossing (they will clear on routes which dont go over the crossing at this time) once acknowledged the traffic lights are red, the signaller then will start the barrier lower process as normal.
then after passage of train the process is reversed, gates up, then release the lock on the traffic lights so they can return to their normal routine.....
be an interesting feature to build in.

As asked before, please do mention the changes, then we can estimate how much work is required (or whether it is needed)

Platform 4 is now Platform 7.
Platform 5 is now Platform 8.
Platform 4A is now Platform 3.
Platform 4B is now Platform 2.
A new platform was constructed on the Southern lines called Platform 1.
Access is given to the "new" Platforms 13, 14 and 15 via Reading Low Level at Reading Southern Junction, with the Down and Up Reading Spurs at Reading New Junction giving access to Platforms 7, 8, 9 and 10.

I've attached the new layouts in the horrific sectional appendix format, as I cannot upload the much more ergonomic and colourful route maps I have!

Not quite - 4A became 6, 4B became 5; the new Southern platform was numbered 4.

The "obvious"/visible changes we're well aware of - that's not the information that we're after.

The Reading area we have very comprehensive info for in light of a Reading sim being developed.

I'm not sure either of you comprehend the level of detail sought to make these changes:- Have any block joints between track circuits been moved to accommodate the longer trains, and by how much? Have any signals been moved and by how much? Changes to speed limits.

A Reading sim would probably mean it's more convenient to have a Reading-Feltham fringe outside the station.

Also, don't forget Feltham itself is getting resignalled soon, which may bring more changes?

Not sure if already covered but in a Feltham timetable I conceived when 10 cars came out of Staines CHS into the up Platform, they then stopped with part of the train still on the crossover. This meant everything described as a 10/458 being only 160m to be sure.

I think you could alleviate that by having it stop at the near end (which aligns the rear end of the train to the platform, rather than the front end), but possibly the train overhangs the signal at the other end in that case?

Yes, but what were the signalling changes? In many cases platforms can be lengthened without affecting the signalling - or the simulation.
The four that come to mind immediately are:
-F5 (Richmond down starter) moved further into the tunnel to allow for platform 1 to be extended
-F254 (Staines up starter) moved closer to London to allow platform 1 to be extended
-F263 (Egham up starter) moved closer to London to allow platform 1 to be extended
-F300 (Chertsey up starter) moved almost 100m closer to Staines to allow platform 1 to be extended, at the same time the former F300BR (formerly on the bridge at the level crossing) moved to the former position of F300.

I believe the signals were also moved at most stations where the signal is right at the end of the platform.

However, I can't be of any further use I'm afraid, there's also probably more important things to do than fiddle a few TC lengths!
