27036's steam heating boiler is clearly in perfect working order, as it stands at Crianlarich Upper station with 27043 on 3 May 1975, whilst working the Wirral Railway Circle 1Z12 Mossend to Fort William 'Road to the Isles' railtour. Despite the nearby Crianlarich Lower station, on the line to Callander, having closed to passengers in 1965, a full decade later this station was still known as Crianlarich Upper.
