In September 2012 at the A1 Trust's annual convention for the loco's contributors at the Nene Valley Railway it was announced that in November 2012 "Tornado" would be repainted into British Railways express passenger blue livery. This was the second livery carried by the A1s after entering service in 1948. The colour was based on Caledonian blue, the livery of the Caledonian Railway (CR), and was only applied to Express locomotives such as the A1s for just a few years before repainting into Brunswick green. This meant that "Tornado" has carried all four liveries that were carried during the life of some of the earlier A1 locomotives.
