Cant wait for that chase! Regarding 7470, at the middle of the 2010s, she had her 15 year FRA mandated rebuild completed. Why wasnt the crown sheet issues brought up then and same with the trucks for the tender. Also , since shes been down for the crown sheet issues, does that count against her mandatory 15 year/days used total?
For starters the 15-year inspection was partially done when the railroad was sold. Pitting was observed during the last boiler washout that management didn't like seeing. After running calculations, the crown sheet still passed the FRA inspection but at a lower pressure and they weren't interested going that direction, so they ordered the crown sheet to be replaced. Last I heard, they were waiting for the new crown sheet to come from the steel mill, and then they were hiring a contractor to come in and weld in the new crown sheet; I guess they have about 2 to 3 months of welding a head of them, so they've hired a big contractor that can handle the job. They are pushing hard to get 7470 up and running again for next year when the railroad celebrates its 50th Anniversary.
As for the tender trucks, cracks were discovered in both trucks, they found identical trucks as replacements only to discover they had the same cracking issue, so they abandoned that idea of finding matching trucks and went with modern trucks with roller bearings.
