Lets begin with what the strategic steam reserve was.
It was a plan by the government to hide away steam locomotives in the case of a nuclear weapon's detonation in the United Kingdom.
What was it supposed to do?

Is there any proof or lead?

What makes this myth probable?

What are the flaws with this?
There
may have been errors in the scrap details even though this wouldn't be likely
for sixty locomotives that were capable of hauling heavy loads. Another flaw
would be getting the coal and water for the engines. Coal isn't a common fuel
source to come about and even then, how long would it take to relocate the
engines, take down any defensive barrier that is keeping them from the outside
world, get the coal and water for 60 large tender engines to them, fire them,
and finally getting them moving for the first time in 50 years, not to mention that
by then they would have rusted internally unless they had deoxygenized water
inside of them.
What do I think?
The strategic steam reserve seems like a good idea and a very plausible myth at that. Even though it is true that a total of 60 8&9F’s were and still are unaccounted for, there are some potholes in the myth. Like for example; as this is a huge mystery, wouldn’t many train & war time enthusiasts have gone to inspect this for themselves and gone to the extent of breaking into the tunnel? Another pothole is that Steam engines take a long time to fire up, especially for large tender engines like the 8&9F’s, not to mention that this supposedly happened in the 1960’s, so by now, it would be likely that the boilers would have expired and rusted unless if people were there twenty four seven making sure that they didn’t rust.
So, this is what I’ve dug up about the SSR
along with other related things. What are your opinions about this? Leave a comment and share with your friends.
