Why is bank station curved?
Why is bank station curved? Bank (central) curves to avoid the Bank of England's vault's at points, so a valid reason there. That's the same reason as before: following the street pattern. The vaults don't extend under the roads, but nor do they descend to the same level as the Central line, so technically the line isn't avoiding them.
