Back in the mid-1990s - when I was a driver at Skipton - one of my colleagues came down from the mess room at Leeds to take a class 142 unit to Morecambe. While walking along the platform, he happened to glance downwards at the sunlit fuel gauge on the leading vehicle and noticed that it was showing virtually empty. After getting down on his hands and knees with an old rag and wiping weeks worth of oil and brake block dust from the gauge glass on the other vehicle, he noticed that there was very little fuel remaining in that tank as well.
Returning to the Station Supervisor's office, he said that he wouldn't be taking that unit as it barely had enough fuel to reach Keighley - let alone Morecambe - and requested - another unit. The Supervisor informed him that there was no other unit available and that he would have to take it. He refused and
the Supervisor made a phone call and requested the attendance of a Traction Inspector. After a few minutes, a Traction Inspector appeared, accompanied by a trainee driver. The TI winked and said "You go back and sit in the messroom. This lad needs some practical experience of assistance procedures!".
Off they went - about 15 minutes late - and, sure enough, the 142's engines shut down in the platform at Keighley. Detonators were placed and red flags shown....and in those pre-electrification days, the following Leeds-Skipton local was a class 144, which slowly propelled the fuel-less 142 to Skipton, dumped it in a siding and then picked-up the passengers again and continued to Morecambe. It's back working to Leeds was cancelled. Considerable disruption ensued for the rest of the day.
