I came across your CRS website while looking for photos of the Vobster Light Railway and i can add some details to the Vobster Light Railway section.
After the VOR closed in 1994 the exhibits were stored in the Radstock area for a few years. Henry & Mary Frampton-Jones moved to Derbyshire and set up the two-foot gauge Derbyshire Dales Narrow Gauge Railway at Rowsley at the Peak Rail site. They moved their locos and rolling stock from Radstock to Rowsley from 1998 onwards and began running trains at Rowsley in 2004 using ex-Vobster Ruston 487963 & Ruston 393325 'top & tailing' the red coach No2. DDNGR trains were suspended from 2015 due to Henry's health problems and most of the exhibits have since moved elsewhere since Henry passed away a few years ago. However, the ex-Vobster coach No2 remains at Rowsley and has been used by the Ashover Light Railway Society in 2022 who have laid a short narrow-gauge line here.
The yellow loco with the 'unnamed gentleman in the VLR vest' - This is Motor Rail 22070 with owner Henry Frampton-Jones in the VLR vest. Henry later moved this loco to Rowsley.
The photo of coach No2 has Henry again visible on the right.
The yellow loco in use with the coach is ex-BR Ruston 393325. Henry is acting as guard on the train.
I hope this info proves of interest,
