59.002 in Aggregate Industries livery contrasted with 59.104 in Hanson colours when the pair worked 7C77, the 12:39 stone empties from Acton T.C. to Merehead Quarry, on 15 February 2016. Although pairs of 59s aren't particularly uncommon on trains between Acton and the Mendips, it's unusual for both locos to be working.
