This product is pretty much 'run of the mill' stuff so far as railway dvds go. It yo-yos at times between catering for the enthusiastic novice as an introductory guide whilst at others it assumes prior knowledge of railway practices. Overall it's well scripted by Paul Shannon (think Past and Present Collection Books) and tells a story rather than just a series of unlinked commentaries.
There's a reasonable selection of archive footage - but nothing that cannot be found in detail elsewhere - Woodhead, S&D, S&C etc... and a bit a of modern footage thrown in.
But overall I'd recommend this product because it does well in two key areas:
1) NARRATION: The narrator makes or breaks railway dvds; so often great material is ruined by at best an unenthusiastic drone or at worst by mumbled and poorly articulated description. The Lost Railways is clearly narrated by PETER FAIRHEAD and is all the better for it.
2) PRICE: At the price you'd pretty much accept anything so the fact it is actually pretty decent makes it a very safe buy.
