The programme was filmed on the Severn Valley Railway, with the part of Hatley station being played by the Arley SVR station in Upper Arley.
The LMS Ivatt Class 2 2-6-0 No. 46521 from the Severn Valley Railway was used on the film set. The engine has now been sold to the Loughborough Standard Locomotive Group and has just returned to service after an overhaul at the Great Central Railway.
The locomotive driven by Arnold and Ralph was given the name Blossom.
The title was a reference to the music hall song and Will Hay film Oh, Mr. Porter! (1937) and a modified version was sung at the end titles by Su Pollard: "Oh, Dr. Beeching what have you done? There once were lots of trains to catch, but soon there will be none, I'll have to buy a bike, 'cos I can't afford a car, Oh, Dr. Beeching what a naughty man you are!"
The entire series is set in the year 1963.
