Speaking of railroad maintenance, do you remember when freight cars used bronze journal bearings, and they had journal boxes with a big wad of cotton or something similar, that was soaked with oil to lubricate the journal bearing?
Back in the late 60s, there was a row of grain hopper cars sitting on a siding at a local feed mill, and one weekend some thieves using hydraulic jacks jacked up the truck side frames which freed up the bronze bearings, and stole all of them out of 10 cars. 10 cars with 8 bearings per car times about 20 lbs per bearing, that's 1600 lbs of bronze.
Never did hear if they caught the culprits.
