But there are other uses of this acronym out there. One is the Strategic Steam Reserve kept by several countries, a collection of old steam locos kept for emergencies where e.g. a fuel blockade stops diesel getting through, the electricity grid goes down, magnetic pulse with all of the engine electronics fried, etc.
So it occurs to me that someone really ought to write a Talking Steam Train Avengers AU, in which all of the characters are steam engines or associated characters etc. E.g.
- Tony is something very high-tech by steam standards but temperamental - e.g., I think there were some experiments with steam turbine trains before everyone realised it was a stupid idea.
- Bruce is powerful and usually reliable but has a bad temper - when he gets angry he sometimes leaks superheated steam and has been known to ignore signals and even run through buffers.
- Thor is a extremely powerful engine imported from Norway, but not very bright. Loki was the next engine built by the same factory, much more intelligent, and resents his "brother" for his stupidity.
- The Captain is a blast from the past, built to pull military trains, extremely powerful and well armoured. He's patriotic to a fault and never backs away from a challenge.
Not sure about Clint, Natasha, Pepper, etc. Nick Fury is obviously the one-eyed Controller.
I'm not the person to write this, I don't know enough about trains, so please feel free to use this idea. If you do a credit would be nice.
