Waterloo station has got the largest number of escalators. 25 together with 2 moving pavements (Travelators) which are serving at Waterloo & City line (Waterloo - Bank) connections.
Waterloo and Bank are bonding well with this so called "The Drain" connection. They're arguing, teasing each other all the time but that's the way of their communication, which shows how close they are. :D
