Was this not realized when they planned this? They spent billions for micro improvements schedule wise. Why even go through with it. Yes the tunnel was provisioned under 63 but other than that it was never sensible. I think with this, second ave subway, London Elizabeth line, infrastructure planners should realize that extremely deep level stations are not an improvement if the time saving are lost getting in and out of the station.

Although it seems like public transport and infrastructure will never go back in the hand of competent people as politicians hold all the control and funding.
