12 years for cross rail, considering it’s scope and unique problems tunneling through some of the most developed subterranean land in the world, isn’t a length of time that most of us would consider absurd. For instance check out the precision and work required to pass (and link to) Tottenham court road. As a counterpoint look at the “new” underground Muni line in San Francisco that is a tiny fraction of the length of the cross rail project and hindered traffic and other infrastructure development for 15 years
