As part of the £5.6 million redevelopment of Blackburn Railway Station back in 2001, a piece of artwork was commissioned by Railwork Plc.
The faces of people associated with Blackburn were laser-cut into 12 stainless steel panels and subsequently displayed on Platform 4. Some of the faces included are Jack Walker (businessman), Barbara Castle (politician) and also Ghandi, as he famously visited the area back in the 1930s. Historic pictures of mill workers and local people are also included in the montage to reflect the town’s industrial past.
The artwork, which is 24 metres long and 2 metres high, took twelve months to complete and was made Scartworks Ltd.
A closer look at one of the panels. The artwork becomes more effective the further back you stand. Be careful not to fall off the platform, though!
If you’re ever passing through Blackburn station, make sure to look out for this piece as it is clearly visible from all platforms.
The British Isles were the limit, but now the world! 
Brilliant. Thanks for bringing this to my attention. May have to swing by when next in London. Beautiful city, one of the best in world.
No problem 🙂 Apologies if I am wrong, but perhaps you were thinking of Blackfriars station? This art is in Blackburn, Lancashire, not London, sorry for the mix up, but I hope you get to chance to visit it anyway 🙂 All the best.
