The railway is said to have very limited rolling stock – one locomotive (restoration of which was completed in episode 1), one passenger coach (restoration of which was completed in episode 3), a small number of freight vehicles (three are specifically mentioned and featured – an open wagon, a box van, and a tanker truck), and a hand-pumped inspection truck.

Despite this plot line, large amounts of other rolling stock are regularly seen in the background of shots – multiple passenger coaches, various freight vehicles, a second steam tank locomotive (in steam) in the opening shots of episode 1, a diesel multiple unit in certain scenes, including the arrival of the Flockton Flyer to meet the road ambulance in episode 4, and a large GWR steam engine under tarpaulin sheeting at Flockton in episode 5.

In August & September 2015 reruns of the series were shown on UK satellite channel Talking Pictures TV.

[1] After being sold into private ownership for preservation, this locomotive was one of the first on the West Somerset Railway, arriving in 1976, and taking part in the opening ceremony a few days later.

During that time, the success of the railway led to the use of longer and heavier trains – beyond the capability of a pannier tank – and Association members decided, reluctantly, to sell it.

Whitbread, who died following a road traffic accident in 2004, is best remembered as a scriptwriter, though he also acted and directed; he was not a novelist.

The publication in the summer of 1977 of a Flockton Flyer children's novel appears to have been merely the adaptation of 6 storylines intended for filming,[4] including a script with all the hallmarks of a Christmas Special edition.
