A giant tetris-like installation has been suspended from the roof of St Pancras International’s Barlow Shed, the fourth leg of London’s rotational public art spaces.

Chromolocomotion, by David Batchelor, has 44 brightly coloured Perspex “L” shapes slotted together in a geometric formation. It is the second piece to be displayed as part of Terrace Wires – the biggest canvas for artists to display their work in the UK.

Terrace Wires follows on from public art spaces Fourth Plinth, Serpentine Gallery and the Tate Modern’s Turbine Hall.

A million people pass through the station every week, making it one of the highest footfall areas in London.

David said: “It offered me the chance to create a piece of work that celebrates the beauty and grandeur of this iconic example of industrial engineering. It seemed appropriate to celebrate this great volume of space above the platforms with something that alludes to these magnificent qualities.”
