Recently refurbished ScotRail electric unit 318253 in the turnback siding at Glasgow's Exhibition Centre station. While mainline trains from Queen Street station are diverted to the electric lines by engineering work, some services from the south are terminating at Anderson's Cross then running forward to reverse in this siding before returning south.
