Darjeeling Himalayan Railway class B 0-4-0ST no. 795 (built by DHR in 1919) has the “adjusted” component refitted.  When this job was completed, the crew got back in the cab, sounded the whistle and started to continue the journey up the mountain.  This led to a scramble to get back in the carriages by the passengers who had got off to view what had been going on.
