Waterloo & City line

Is the Waterloo & City line running today?

The Waterloo & City line is the Underground's smallest, simplest and most single-purpose line. It has just two stations — Waterloo and Bank — and exists for one reason: to carry City commuters between Waterloo mainline station and their offices in the financial district, twice a day, five and a half days a week. It does its job and goes home.

Where it runs

The line runs in a deep-bored tunnel directly between Waterloo and Bank, roughly 2.4 kilometres long, beneath the River Thames. There are no intermediate stations. The journey takes about four minutes door to door.

A bit of history

The line opened in 1898 as the Waterloo & City Railway, built and operated as a subsidiary of the London & South Western Railway (later the Southern Railway, then British Rail) to carry its commuters arriving at Waterloo into the City. It was the second deep-bored underground railway in the world, after the original Stockwell to King William Street section of the City & South London (now Northern).

The line was operated as a part of the mainline railway, not the London Underground, until 1994, when it was transferred to London Underground. It was upgraded in 2006 with new signalling and a refurbished fleet of trains shared with the Central line.

The "Drain"

The line's universal nickname among City workers is "the Drain". The name refers both to the deep tunnel — it runs significantly below the river — and to the way it draws commuters from Waterloo into the City each morning and pours them back out each evening.

Notable stations

• Waterloo — interchange with the Bakerloo, Jubilee, Northern and the South Western mainline; gateway to south-west London and beyond.
• Bank — recently rebuilt, interchange with the Central, Northern and DLR; the heart of the City of London.

Step-free access

Both Waterloo and Bank are partially step-free, though access to the Waterloo & City platforms specifically remains limited. The Bank rebuild improved access significantly — check the latest TfL accessibility map for the most current information before travelling.

Hours

The Waterloo & City line operates only on Monday to Saturday, and only during the daytime — typically from around 06:15 to 21:30 on weekdays, with a shorter Saturday service. It does not run on Sundays at all, and it does not run on the Night Tube. The line's operating hours reflect its commuter purpose — outside of those hours, journeys from Waterloo to Bank are made via the Jubilee or Northern lines.

Common quirks

• Four minutes, no excuses. The line is reliable to a fault — when it runs, it's almost always punctual, because there's nothing to go wrong. Two stations, one tunnel.
• Same trains as the Central line. Waterloo & City trains are 1992 Stock — the same as the Central. The shorter trains used here are five cars rather than eight.
• Bank end is at the eastern side of Bank station. If you're transferring at Bank to the Central or Northern, allow a few minutes for the walk — Bank is a large station complex.
