waterloo and city line

[filthiestfis]

what is the colloquial term often used for the waterloo and city line? (London tube)

[skylight]

Hi filthiestfs, The Drain cheers skylight

Between Waterloo and Bank stations it`s known as The Drain, so called because of the dark tunnels, and fast running trains.

Honestly, I thought it was a joke! Thanks everyone!

[dzug]

Also cos it's built with smaller tunnels than a standard tube line

Just as an add on to the above, which are correct, the depot has a habit of seeping water from the Thames, and as a result, just a few Rats.
