Virginian PA locomotive speed

[NW Mailing List]

Personal opinion:  Land speed records should be accepted only if standardizedconditions have been established in advance.  Example: records in track and fieldrequire an eight lane track; specified head wind / tail wind, etc.
The claim of 112.5 mph for NYC 999 is dubious; because of known factors ofboiler capacity and cylinder volume; also because observations were largely estimated.
The 'World Record' of 126 mph for Mallard is likewise dubious, because it was established on a downhill grade and documented by what some consider as a couple of 'blips' on thechart.
>From what I have read, the reported 140 mph for a T-1 is too poorly documented tobe accepted as fact.  But 'legends' seem to have a life of their own.

What’re your thoughts on the anecdotal reports of PRR T-1’s hitting the 140 mph mark west of Crestline, OH?
It’s been a while but I think the first time I read that might’ve been in Alvin Stauffer’s book on Pennsy Power.

Subject: Re: Virginian PA locomotive speed With the 69” drivers and the cylinder dimensoins, the PA’s could be expected to cruise at 85 MPH range.  The N&W 100-series engines could be expected to run in the same range. The Js can’t be considered in comparison with ANY other steam locomotive.  They were so well designed including their counterbalancing that they could operate comfortably at driver RPMs in excess of 500 and could reach speeds in excess of that.   Remember that if a locomotive  operating a a speed equalling their driving wheel diameter, those wheels will be turning up 336 RPM.  There were many locomotives that could operate in the 400 RPM range.  There were others not comfortable at 336 (the Atlantic Coast Line’s 1800-series Northerns, for example). - Ed KingFrom: NW Mailing List via NW-Mailing-List Sent: Friday, February 07, 2020 12:13 PMTo: 'NW Mailing List' Cc: NW Mailing List Subject: Virginian PA locomotive speed Hello,I wondered if anyone can tell me how fast the Virginian PA passenger locomotives could or did run?  I’m wondering about their designed top speed and normal schedule running speed. I’m sure it’s slower than the N&W J’s but would they have been comparable to older N&W passenger engines?
