156474 fleetingly emerges from the bushes, to cross the viaduct over the River Cononish at Dalrigh on 24 June 2013. It is working (along with another unit hidden by the vegetation) the 1Y24 12:56 Oban to Glasgow Queen Street ScotRail service. Note the amount of strengthening that both the piers and the arches of the viaduct have received.
