How strange that was to watch. I recognise some of the names of Drivers there. During the school holidays in the 1980s my Dad, by then a Traction Inspector, got me a small job entering Driver performance data into the then newly computerised system.
It is true what they were saying in this video- KX was like a big friendly family and as a lad in those days, nearly all staff were encouraging lads to join the railway on leaving school. Taking a trip out for a few hours and likely as not if spotted, a Driver would be asking "why are you sitting back there? You'll never learn the job from a carriage." Never even needing to ask for a cab visit, it was encouraged.
They were a great bunch; Drivers, Guards, Shunters, Bounds Green Engineers, all the support staff- all a wonderful family of people.
