Next month the new ticket hall for Thameslink passengers (and, in the future, Crossrail) will open at Farringdon station. The video above, produced by Network Rail, shows a fly-through around the new bits.
The ticket hall, opposite Farringdon's existing entrance, leads passengers down to the newly-extended platforms, which will accommodate the 12-car trains that First Capital Connect will introduce from 12th December. Lifts providing step-free access to the platform level will open next year.
With the new hall opening, the existing Grade II-listed entrance, with it's façade bearing the legend 'Farringdon & High Holborn Station' (itself currently undergoing restoration work), will be closed to allow refurbishment and expansion work, and to link it to the new concourse. It will re-open in February 2012.
When the work is complete, and Crossrail opens in 2018, Farringdon will be one of the capital's busiest stations, with high capacity north-south and east-west routes linked to the Hammersmith & City and Circle lines on the Underground; at peak times up to 140 trains an hour will pass through. Not bad for one of the oldest stations on the network.
Cheers to @TomSEdwards for the video tip-off
