158817 Mexborough 2 March 2002

A forbidding sky hangs over Mexborough station on 2 March 2002, but the gleaming paintwork of 158817 tries to compensate as it speeds through the station. Quite what an Alphaline Class 158 is doing so far north is not certain, but judging by the ex-works condition, I would assume that it is heading back to the West Country after being repainted. Confirmation anyone?
