Recently I've been getting some suggestions in my Youtube feed from the BBC Archive. This documentary from 1956 looks at the problems facing NI railways. Could ,or indeed should, anything be done to save the railways?
We all the know what the answer ultimately was ... but this is a fascinating look at how the issue was presented at the time.

Even more fascinating for someone whose parents were just toddlers in 1956, this video also shows in detail how trains and buses operated in the 1950s - have a look from 10:32 for all that goes into a journey.
