London train stations: From Waterloo to King’s Cross, the capital’s biggest stations by platforms

From St Pancras to Waterloo and Victoria, London is not shy of a few grand and well-connected train stations. Its oldest, according to Network Rail, is London Bridge, having been opened on Tooley Street on December 14 1836 by the London and Greenwich Railway.

The capital’s busiest station, as of March 2022, was Waterloo, recording a massive 41.43 million passengers over the preceding 12 months. Unsurprisingly, according to the Office of Rail and Road (ORR) data, London stations made up eight of the 10 busiest stations in the UK over that same period, and all of the top seven.

Another major station, Old Oak Common, is currently being built in west London to act as the terminus for HS2, while the work on its eventual end-point at Euston is completed.

Due to open in the 2030s, it is expected to welcome around 250,000 passengers per day, and will consist of a total of 14 platforms.

But what are currently the biggest stations in London? And where will Old Oak Common fit in once complete? Below, we take a look at some of the capital’s largest stations based on their number of platforms.
