Not another Kings Cross Timetable... KGX Platform Blockades

I'm not sure if this is something that's easily able to be done, however the December 2020 timetable runs with a block taken for King's Cross platform 0. Would this be able to be considered to be added as a scenario in any future KX sim version? Presumably same could be done for the platform 0-6 closure now in force. Just a thought, if it's something the developers would be able to consider.

This looks truly fun... But I have previous with getting in a muddle with setting up possessions etc. I assume that this cannot not be built in so that when you load up the timetable they are in place? If not, I guess I will have to learn fast because I would love to give this a spin

As mentioned earlier there is no way for me as a TT writer to have this load as a scenario. It would need to be the sim developer i think.

It does take a while to impliment all the engineering possessions but you dont need them all really.

Could you not seed a train into the platform to occupy it, then have it set to depart after 48 hours or something?

Do trains have a maximum length? If not, you could make a train so long that its tail will be just past Holloway South on the FL, and its engine at the buffer stops of platform 6.

Done a couple of quick tests and it will probably work for Kings Cross but there are pitfalls depending on the individual circumstances.

In some cases, seed trains are truncated. This problem was raised a while ago (Mantis 0015307, 13/05/2016). The reason for the truncation was explained as, "The train will extend back as far as the pointwork will allow. The "truncated" message only occurs if the train attempts to seed over facing (in the train's direction) points set the wrong way. In other words, you'll only get this message if the train would otherwise split a set of points. The idea was to warn the developer that they've seeded it somewhere impossible.". After some discussion it was decided that no further action would be taken as, "Experience since this ticket was raised shows that it's better to simply seed the train elsewhere.".

You can see it happening if (for example) you run any of the TUE to FRI Carlisle 1979 TTs where 4S50 is truncated by the core code to fit into the relevant platform at Carlisle on seeding.

It's a possible solution for the Kings Cross station area but not a panacea.

Truncating could be avoided by misusing an entry point, such as Hornsey EMU Depot.

Which is a totally different proposition to that which you originally proposed. There is no need to keep on coming back with different propositions just to prove that you can never be found wrong. I merely made the point that your original solution was not guaranteed to work and gave the reasons why so people would not take up the idea and then perhaps be disappointed. Of course, if you were to do the background work and cover all the options when you make a proposal, those of us who have already addressed the issues in the past would not need to point out the possible problems.

It just goes to show what a bore modern-day timetables are. The sim has to be restricted to make them even vaguely interesting.

Nice one.

Bit of testing and you don't need to put any times in at all. Create a TT with the seeding location of platform whatever and a first entry in the TT of that location with no times. When the sim opens that train has a little shuffle then sits down at the end of its TT as "Terminated, no more timetable trips". You can minimise the shuffle if you set the seeding gap to 1. TT to show P8 at KGX blockaded attached.

Edit: Only works at key locations so needs a bit more thinking to see if it can be made to work for something like a Gasworks Tunnel blockade.

... to do this you just click the track circuits tab....

Latest manual to go with the TT.

TT should be released early May.
