"Tornado" has seldom needed help but, being a 21st Century machine, has to live by the iron rules of Health & Safety (etc. . . .). Thus, when its TPWS device ceased to work the locomotive, although perfectly fit to run, was not allowed to head a train (The North Briton) so was piloted by a DB class 66 all the way from Doncaster via the S&C to Newcastle on 24th February. We see the pair on the S&C at Lunds then at Hexham (which still boasts its beautiful over-line signalbox) and then, having left the train at Tyne Yard, passing through Durham in the dark with its night-time illuminations on. It was on its way to Grosmont.
