A sight to gladden the heart of any classic diesel enthusiast, but it can only be guessed what the highly conservative steam enthusiasts thought! GWR Hall class 4-6-0 4936 Kinlet Hall's inaugural main line run did not go at all well on 17 June 2000 and diesel assistance was required for the return working from Didcot. The Vintage Trains Birmingham Snow Hill to Didcot 'SLS Special' railtour had traveled outward via Cheltenham and was due to return via Banbury. However, leaking tubes and injector troubles to say nothing of a hot axlebox on the tender resulted in 37668 being added at Didcot. This unusual combination is pictured approaching Wolvercote Junction with the 17:20 Didcot to Birmingham Snow Hill return.
