# When did the London Underground last gain a line?

**When did the London Underground last gain a line?: 24 May 2022**

The Elizabeth line opened

It was four years late and several billion over budget, and is not strictly part of the Underground — it is a separate railway on the same map and the same ticketing. Before it, the last genuinely new line was the Jubilee in 1979. Within a year of opening the Elizabeth line was carrying more passengers than the entire national rail network of several European countries.
