A group of children thwart crooks in the Far North of Scotland

This Children’s Film Foundation production makes good use of the Aberdeen-Inverness line with Forres standing in for ‘Moorlands Junction’ and Elgin representing ‘Rioch’. There is a lot of relatively rare footage of Class 120 DMUs, though continuity errors show both 3 and 6-car trains on the same journey! A nice touch though is that one of the childern is reading a copy of Locomotives Illustrated No.11 with a Class 76 electric locomotive on the front cover!
