Filmed in 2005, the idea behind these three DVDs is that the film maker turns up unannounced at a heritage railway, giving the proprietors no opportunity to make "special arrangements" for him, and proceeds to record what a normal visitor would experience. This is then edited and overlaid with a commentary telling the history of the line from its conception to closure and on to preservation.
As you might imagine, the results are mixed, although the actual picture quality is excellent throughout.
The best of these three films is the one made at the Severn Valley Railway, where there are lots of ex-GWR locos both in and out of steam and there's plenty going on to keep us entertained.
The West Somerset Railway is also quite entertaining, although, as they have less there to look at in terms of stock and activities, we spend more time than ideal hanging out of carriage windows filming the journey between stations.
Which leaves the DVD dedicated to the Battlefield Line. Unfortunately our host managed to arrive on a day when the only steam engine in steam was a tank engine masquerading as Thomas, which was offering platform rides, and so almost all of the film consists of a trip behind a Class 33 diesel. Steam engines are seen (briefly) at 21'44", 22'22" and 27'30". It doesn't help that the sound level of the commentary on this particular disc is very variable.
