Parked up in Uppermill square is Albion Aberdonian 716A, the A-suffix denoting conversion for one-man operation. I cannot find a working from Uppermill to Denshaw on the 158 in any timetable I have, except very early in the morning. This could well be the bus working the 156 which made a trip from Uppermill to Denshaw at 1730. This would follow exactly the same route as a 158, but I don't know why the driver would change the route number.
