This info IS handled in the Keystones, regarding proper T1 operation. I would appear that most of the problem lay with
engineers on the extra board, and those who knew nothing but K4s operating traits. The older gents, who had cut their
teeth on the roads E class atlantics knew all about handling potentially slippery locos. There is absolutely no question
that running a T1 was a completely different type of experience than that of the big Pacifics that preceded them, with
the possible exception of the K5. There also appears to be a bit more negativity from the Lines East crews than with the
Lines West operators. The combination of grades, frequently 1% or more, plus gobs of inclement weather, may have
put an extra bit of strain on the locomotives and their crews. PRR locomotive maintenance at this time was also a real
problem, no matter what type of motive power you were running. When the T1 showed up for the test on the N&W in
1948, the sanders weren't even correctly aimed at the wheels! Neither they or C&O reported excessive slippage with
the engines tested. Anyway, I also hope that someday a really complete Book of T1 fact will see the light; there has been
a ton of good solid info uncovered in recent times, and I suspect that there's even more to be had. Even with the info
available today, such a book would turn the railfan community on it's ear, for sure! I'll even go a step further, and say
that next to the J1 2-10-4, the T1 was, in it's final form, Pennsy's best!
