Within hours, the mighty Monarch of the Glen was moving again, thundering through the Scottish Highlands with 80 passengers after being effectively jump-started by a recovery crew.
Trouble befell the 13-coach train on a luxury excursion from London to Scotland when it pulled into Edinburgh early on Saturday.
The train was found to have a faulty generator van - needed to power lighting and air conditioning on a day when temperatures were set to reach 78 degrees. BR's control centre at Crewe was alerted but realised the van needed a charger of a type not found at maintenance depots.
So it called the RAC, which alerted a contractor near Edinburgh. The recovery crew borrowed a BR trolley to move two huge batteries alongside the train and got the generator van operating again - leaving British Rail with a call-out bill for pounds 92.50
