These logs were kept by the fitters at Llandudno Junction depot and detailed the fuelling, mileage and repairs (on depot and off-site) done for power cars (and some locomotives).
These were found during a house clearance and Phil Brown kindly passed them on to me to make them available for all to see. They seemed to have been a complete collection from the late sixties to the eighties, but sadly one of the two parcels got lost in transit via courier so only half now survive. I will add them here as time permits.
The books were mainly foolscap size, too large for a single scan on my scanner. Sometimes for foolscap documents I do two scans, top and bottom, then join them in Photoshop, but for the volume of pages do for these it was faster to photograph them.
The images were then combined into pdf files which have mostly been split into parts to keep the file size reasonable.
Llandudno Junction had a DMU allocation from 1958 to 1968. Details can be found on the depot page.
