Signal failure or TCF on 4 track mainline Today at 20:32 #158770

Hello,

I'm sure this has been asked on here, the search feature came up with just about every TCF/Signal Fail topic on the actual sims, too many results, I thought I asked before but I can't see all my post history, but either case if a signal failure or a TCF occurred on and Up Fast line, would everything logically be re-routed onto the Up Slow, but would that depend if a stopper was in the way?

Say a TCF happened at Elstree & Borehamwood Up Fast, would an East Midlands St Pancras express be routed off at Radlett Jn and trundle down the Up Slow to Cricklewood to crossover back onto the Up Fast, but say a stopper had already got to Elstree or Mill Hill Broadway and now that East Midlands is stuck behind that, would it therefore be quicker to 'talk it through' the TCF?
Or is it a case of hold the stopper and delay that until the East Midlands set has crossed over and got ahead, but being a Thameslink service just been held, it's pathing south of London is now out the window

Any help appreciated!

That's for you to decide based on your workload and performance.

There is no rule that says if you can route trains around the problem you must. There is nothing to say you can only "talk by" signals if you have no other option. You are playing the part of a trained, skilled signaller working with trained, skilled drivers. You have the option to "talk by".

Of course in reality it's likely you're going to need to grant line blockages so the S&T can go out and investigate and hopefully fix it (sometimes it's better to live with the problem until the end of the passenger service because it would be too disruptive to get the fix done). In that case obviously you will have to work around it, although you might very well decide to give only a 10 minute block because you're going to want to talk the next one by the signal after that.
