158723 passes Plean on 21 July 1997 with the 16:25 Glasgow Queen Street to Aberdeen ScotRail service. This view is unrecognisable now, with the line wired at 25kV, and the bridge in the background demolished. Also gone is the semaphore signalling and the extremely tall Plean Junction Signal Box, which closed in 2008. Plean was formerly a double junction, with a line diverging to the north serving Bannockburn and Carnock Collieries, and a line to the south serving East Plean Colliery.
