I've always liked trains, facinating.
Moreso when I went to work for GATX building railroad tank cars. Biggest tank car manufacturer in the USA, our plant was 3 1/2 miles long from end-to-end. Biggest annealing furnace in the USA to anneal 2 or 3 cars at a time.
I spent one year in new car then three more in plant engineering/maintenance, took care of repair shops all over the USA. Really got to know a lot about the business including it was more economical to buy cars from non-union shops and slap our "GATX" on them than pay our highly paid welders and staff including running own Waste Treatment Plant.
They still have the biggest leased fleet, or did as over a decade or so ago.
Well they finally shut down new car, great job while it lasted.
Too bad our counrty turned away from rail to trucking and interstates, big mistake!
But I still love and appreciate trains.
