Railway Roundabout is the seminal 1950s and early-'60s children's railway news programme.
Gathered together into this bundle is the complete archive of the cult series, featuring a diverse array of topics across BR's huge network.
A lot of the footage, understandably, focuses on the ongoing reduction of reliance on steam power and the introduction of diesel and electric alternatives.
There's an incredibly broad scope to these programmes with the directors seemingly happy to point their camera at anything that moved, and plenty that didn't.
They are a mine of information for anyone interested in the period, steam locomotives or as a reference point for railway modelers. Oh, and they're really interesting to watch as well.
