1961 built Ruston & Hornsby 0-6-0 459515 Iris approaches Thame Junction on the Chinnor & Princes Risborough Railway with the 09:30 freight (all brake van and no freight!) from Chinnor on 17 October 1999. This was running as part of the line's Diesel Gala. The train is just approaching a crew operated level crossing over Horsenden Lane, at which point the line starts to curve to the right after traveling roughly in a straight line all the way from Chinnor.
