Can anyone provide definitive information about the scrapping dates (years will do) and locations of all 52 PRR T1 Duplex steam locomotives? The only source I could find on the Net says that "all were scrapped by 1953", but I find that date rather early in view of the fact that most T1's were not even built until 1946. In contrast, all but two of the NYC Niagaras were retired and scrapped in late 1955, with one lasting as long as June, 1956 and one (S-2 poppet-valve #5500) scrapped earlier.
The last TEEs were sold in Dec. 1955, IIRC. They were shipped west in early '56, but I can't tell you exactly when. This
info has appeared in the Keystone over the last nine years or so. This last bunch was a group of Baldwins in the 5540
series, and included the T1a 5547. It's utterly tragic that #5500 was not spared, as she was the Silver Bullet of the
whole TEE fleet. Too bad the TEEs were so loaded with aftermarket parts, or perhaps they might have made it to the
very end in late '57.
