What does the future hold for our bus museums and collections? The Bus Inspectors uncover the challenges of preserving our modern bus history and hear why there are some gaps in our national collection. Katariina Mauranen, James Freeman and Maxson Goh talk about the transition from spanners to keyboards in the workshop, while Stefan Baguette from Alexander Dennis considers the preservation prospects for today's electric buses. Plus, highlights from the 1930s at Amberley Museum in Sussex and the 1910s at the London Transport Museum Depot at Acton as The Bus Inspectors continue their national grading project... and Tim Hedley-Jones from the Railway Heritage Trust provides a perspective on grading and the importance of prioritising our heritage.
