"Railway Memories Number 23" recalls the time when passenger trains hauled by vintage steam locomotives ran all the way from Northallerton to the Settle & Carlisle line at Garsdale, when express trains including one of the nation's most prestigious Pullman trains served or passed through Britain's 4th smallest city which has had no railway at all since 1969, when meandering branch lines - including one of the few passenger railways to escape nationalisation in 1948 - connected small market towns to the outside world, and when great Pacifics and Deltics ruled the East Coast main line. "Railway Memories Number 23" lavishly illustrates the East Coast main line from Northallerton to the outskirts of York, the old Leeds Northern main line from Ripon to Thirsk, Northallerton and Picton, the whole 44 miles of the Wensleydale line, as well as the branches to Masham, Thirsk Town and the private Easingwold Railway.
