Commuters can also expect to encounter delays on the Tube, with severe delays on the Hammersmith & City, District, Circle, Piccadilly and Victoria lines this afternoon.
The London Midland twitter account posted a tweet stating that fire alarms at the station are sounding, and there were no arrivals or departures until the "source of the activation is investigated".
However, minutes later the same account posted a tweet which said the station had reopened and services will recommence "shortly, albeit with delay".
British Transport Police said the incident was a "false alarm".
Euston station briefly closed whilst @LondonFire investigate a fire alarm. False alarm and station reopening. Thanks for your patience 👍— BTP Euston (@BTPEuston) March 16, 2017
