ERTMS 2 A.T.O. signalling will be operational shortly on the Thameslink line. If a technical fault arises within 30 seconds trains will stop, and trains could then be driven by the train driver. My question is if only one direction of travel is affected will the other line still operate in A.T.O. mode? What affect if a failure occurs beyond Blackfriars where there are junctions and will this disable the other line and converging lines A.T.O? Once the fault is cleared how would A.T.O. be resumed?
I didn't find the right solution from the internet.
