This consists of photographs of Welsh and other British locations (from Lairg to Moretonhampstead), mostly in the period from 1959-1968. Many locations have more than one photograph of the facilities. A list is available.
As well as drawings that were passed to Mike by Trefor (T.L.) Jones, there is a photographic collection. This a mix of Welsh-subject photographs copied from other publications and Mike's own photographs taken during his travels through mainly Cambrian country.
A catalogue of 'thumbnail' images is gradually being compiled and distributed by means of the quarterly Newsletters.
Colin was a meticulous researcher and his wish was that the results of his researches into the railway history of the Cardiff Valleys and the Vale of Glamorgan should be readily available to other like-minded researchers. Thus the original pages, over 22,000 in 112 lever-arch files, have been donated to Cardiff Central Library.
However, the Circle funded the commercial scanning of the entire Collection, both as a back-up for the Library and for the use of Circle members. There is no detailed catalogue of the transcripts and photocopies Colin's files but they are easy to navigate since the pages are assembled in fairly strict chronological order.
A full list of the volumes in the Collection can be supplied to members and the Circle can advise all researchers as to possible sources of photographs and other material.
John Hillmer has donated a number of modern photographs, from c.1991 onwards, to the Circle. These are available for inspection at the Circle's Research Centre at Rhiwderin.
