Notes:
The text in this Quainton Railway Society publication was written in 1989 and so does not reflect events in the 25+ years since publication. The text and photographs are repeated verbatim from the original publication, with only a few minor grammar changes but some clarifying notes are added if deemed necessary. The photos from the original publication are provided as scans in this internet version of this long out of print publication.
