37405 passes Forteviot on 6 September 2000 with the early running 6D53 12:20 Perth to Mossend Enterprise service, entirely comprised of loaded timber wagons. There was plenty of warning of this train's approach, as not only can the line be seen for well over a mile in the Perth direction, but also the 37 was not hanging around and could easily be heard some considerable time before it came into view!
