I am starting to feel that the Crossrail tunnels may never open with the current situation, much like the Croxley Rail Link. While the above-ground sections may be repurposed for existing services, the tunnels would become a national humiliation, first with the sheer underestimation of the costs, and then a certain event which I cannot mention outside the temporary sub-forum. I cannot really trust the current British government to bring that certain situation under control when South Korea does it better (if I recall correctly).
