I was at Steamtown today and was talking to one of the guys in the shop. I asked him if he knew what the "%" meant on the side of the engine by the road number. He didn't know as anyone he asked didn't know. Any idea?

53% paid off???
the only number 53 I see in the stats is the tractive effort = 53,115 lbf (236.27 kN)

Where's Jack and the other pros?
weight to factor of adhesion ratio?
The percentage of every dollar that gets to the rail.
It seems to be tractive effort in thousands of lbs.

I found this explanation on this Website
D� x S x 0.85P | = Tractive Effort Lbs |
Variable "D" is the cylinder size in inches, while "S" is the stroke in inches and "P" is the boiler pressure in P.S.I. For a locomotive like 6167, the formula works out to:
25.5� x 30 x 0.85 x 250 | = 56,785 Lbs |
Which, when rounded up, is the locomotive's haulage rating (57,000 Lbs = 57%)
Definitely. That smokebox-centered headlight has GOT to go.

Agreed! The Strasburg scheme with the repositioned headlight looks much better. And now the purist C.N. fans will now commence the snowball and beer bottle throwing!
Eh. I prefer her in her original CN/Grand Trunk look versus a made-up Pennsyfied version.

Haha. Well, you keep the steam engines running, and I will always be a steamfan 100% of the time Kelly.
The % on the cab sides of Canadian National, Central Vermont, Grand Trunk (of Maine) and Grand Trunk Western steam locomotives was the % of 100,000 lbs of tractive effort that the particular locomotive had. For Example, CNR and GTW 4-8-4 locomotives had 57% on the cab sides......57,000 lbs of tractive effort.
No Canadian National or subsidiary company steam locomotive exceeded 100,000 lbs TE. That included the ex Boston & Albany USRA heavy 2-10-2's acquired in later years by CN, or Central Vermont 2-10-4's.
