By the time Canal Tunnels are bought into service on Thameslink, presumably the Thameslink core will be about as upgraded as it is going to be. I see the ridged overhead conductor is done and ETCS trials are underway but its still an old railway using some old tunnels.
My question is what happens if there is a problem on the Thameslink core causing delays to trains, cancellations or a complete blockage of the line? What plans do Thameslink have for service resiliency if the core is out of action?
Surely if there were to be a problem in the core once the full service plan is up and running it could potentially affect all of the feeder lines?
Presumably at some point Thameslink will give up some platform capacity at Kings Cross mainline station as they'll be diverting a large portion of ex WaGN services down the Thameslink core. If there is a problem in the core where would these services get diverted back to without causing even bigger problems?
It seems a little bit short sighted that the new St Pancras A/B platforms weren't constructed with four tracks or at least three in mind to allow for terminating/reversing services from the north and easy transfers in this event.
Blackfriars, by contrast seems a lot better thought out with its two reversing/terminating platforms available for the south.
PS I have asked Thameslink about this. Met silence.
