Over a period of 2 days in December 2004 I recorded the move of groups of 37s 47s and 56s being moved from Cardiff Canton to the old Margam Depot. Due to the logistics of being in the right place at the right time only the final move, almost in darkness at Canton, was caught departing. But thanks to the
cooperation of the staff at both depots, no doubt you'll see many long forgotten locos.
