My Nottingham friend Stewart alerted me to a BBC News item about “Nottingham’s ‘secret’ railway tunnel”: https://www.bbc.co.uk/news/av/uk-england-nottinghamshire-45902996/inside-nottingham-s-secret-railway-tunnel.
The “secret” tunnel is accessible – if you have the key to the right door – from the basement of Nottingham’s Victoria Centre, which is built on the site of the old Victoria Station, opened in 1900, closed in 1967 and quickly demolished.
This was Weekday Cross Tunnel (418 yards), stretching from the south end of the former Victoria Station towards Weekday Cross Junction, where nowadays the NET tram leaves its viaduct to run along the street towards the Lace Market. The tunnel was used to carry pipework for the Victoria Centre’s heating system, and the track-bed to the south was later blocked by the Centre for Contemporary Art Nottingham art gallery, now Nottingham Contemporary (opened 2009).
In fact, the BBC’s “secret” tunnel isn’t even half of the story.
Beyond the Victoria Station site, the railway line headed northwards into Mansfield Road Tunnel (1,189 yards) which runs almost directly beneath Mansfield Road, emerging eventually just past the road-junction with Gregory Boulevard: https://www.28dayslater.co.uk/threads/mansfield-road-tunnel-nottingham-may13.80919.
Here in an open cutting stood Carrington Station [http://www.disused-stations.org.uk/c/carrington/index.shtml], opened in 1899 and closed as early as 1928, a commuter station that stood no chance against the competition of Nottingham’s trams.
Carrington Station cutting has been completely filled in and built over as part of an Open University campus, and the street-level building, for years occupied by Alldogs Poodle Parlour, has gone.
North of Carrington Station the railway ran into Sherwood Rise Tunnel (665 yards) [https://www.geograph.org.uk/photo/2388076] which is blocked by further landfill at the north portal.
Until the mid-1960s these three tunnels, all of which remain intact, were a practical direct route under Nottingham city-centre.
When Victoria Station was demolished there was apparently talk of leaving a right of way beneath the shopping centre, but in the event the basement car-park was built the full width of the station’s footprint. (It was not unknown for 1960s/1970s shopping centres to include provision for underground rail transport [http://www.mikehigginbottominterestingtimes.co.uk/?p=2274]).
The blocking of the railway track-bed at three locations, successively in the 1960s, late 1980s and late 2000s, means that a direct route, wide and high enough for a double-track railway and therefore feasible as a light railway if not a roadway, lies utterly unusable beneath the congested streets.
At the time of the Beeching cuts, planners and railway managers clearly believed that the Victorian infrastructure they inherited would never be needed again.
It’s a matter of opinion whether this amounted to naivety, stupidity or arrogance.
They left future generations a legacy across Britain of miles of derelict strips of land that could have been adapted to transport uses undreamed of in the 1960s, if snippets hadn’t been handed over for buildings that could easily have been located elsewhere.
