In contrast to the colourless smog which has lain over London, Scottish artist David Batchelor’s sculpture, Chromolocomotion, brings a splash of colour to the Grand Terrace at St Pancras International. Unveiled this week, the 20 by 10 metre work consists of 44 L-shaped pieces of coloured perspex suspended from the Grade I-listed roof of the Barlow Shed. It replaces Lucy and Jorge Orta’s Cloud: Meteoros and is the second installation commissioned by St Pancras International’s owners HS1 Ltd as part of the Terrace Wires initiative. The work will remain in place until late September. For more on the initiative, see www.terracewires.co.uk. PICTURE: HS1 Ltd.
