The Bennett Brook Railway channel of railway archive films on YouTube shows Training films on everyday tasks such as track maintenance in the age of steam, including these great 1950s track gang.
To me they look just like the Airfix track workers still available from Dapol.
You can access the channel via YouTube through their railway newsreel archive posts such as: https://youtu.be/MGszU8cA8_I
It’s all the everyday detail that make such films fascinating.
