My fellow Dull Men's Club member had spotted a Class 121 'Bubble Car' at Princes Risborough railway station and it reminded me that I'd seen them before at Aylesbury station.

What I hadn't realised at the time was they are the longest serving DMUs in the UK, having started life in 1960. I thought they were en route to a heritage day or line, not that Chiltern Railways were still regularly using them in service!
Unfortunately the end of the line is nearing for the Class 121 'Bubble Cars' as spare parts are becoming more difficult to source and the engines are getting ever more frail.
