Let's see. Take a few examples from British railways:
Class 08 - 450hp English Electric prime mover, I6. That's 75hp per cylinder.
Class 27 - 1250hp Sulzer prime mover, I6. That's 208hp per cylinder.
Class 33 - 1500hp Sulzer prime mover, I8. That's 188hp per cylinder.
Class 37 - 1750hp English Electric prime mover, V12. That's 145hp per cylinder.
Class 40 - 2000hp English Electric prime mover, V16. That's 125hp per cylinder.
Class 43 - 2250hp Paxman Valenta prime move, V12. That's 188hp per cylinder.
Class 47 - 2500hp Sulzer prime mover (derated), H12. That's 208hp per cylinder.
Class 50 - 2700hp English Electric prime mover, V16. That's 168hp per cylinder.
Class 55 - 3300hp across 2x Napier prime movers, D18 each. That's 92hp per cylinder.
Class 58 - 3300hp Ruston-Paxman prime mover, V12. That's 275hp per cylinder.
Class 66 - 3300hp GM-EMD prime mover, V12. That's 275hp per cylinder.
So, quite a wide range of values, reflecting both progress over time and differing design strategies between manufacturers. EE consistently used smaller cylinders than Sulzer, for example, while (most remarkably) the Ruston-Paxman engine in the 58 is a direct descendant of the EE engine in the 37, while developing double the power. Meanwhile the Class 66 is representative of common American locomotives, being a pretty straight derivative of the SD40-2.
It looks as though typical values for power-per-cylinder range from 145hp to 275hp. Outliers like the decidedly early Class 40, the very cheap and conservative shunters, and the very exotic Class 55 can be discounted. Even 145hp is decent for a family car, I think...

Well, I think it's pointless to argue, since that was no mere shunter, that was a six-axle road locomotive, with two others lashed up behind it pulling what, at rough count, was about 80 cars worth of shipping containers. I still say he wins Maybe not in the 1/4 mile, but definitely at the dynometer.
I've also discovered a new and interesting "problem" I didn't exactly forsee with the car, I can't stop and get gas without people asking questions and wanting to know the specs :P nobody ever asked me about back when it was a bit more beat up.- They say nothing good happens at 2AM, they're right, I happen at 2AM.

Oh, and that locomotive? That's a new-ish GE ES44AC, part of the "Evolution" series, which depending on configuration, throws out 4,000 to 6,200 horsepower! That's a whopping 333 to 388 per cylinder
Arga, the car looks great! I too did the "locomotive and car shot" awhile back, oddly enough against an NS locomotive somewhere along the Monongahela Line.Aerodynamics are for people who can't build engines. --Enzo Ferrari

Thanks.
I've been shooting train pics at that spot for a long time. How long? Since U-boats in Conrail blue were hauling loads of truck trailers though there since the tunnels at Spruce Creek meant no double-stacks until 1998.- They say nothing good happens at 2AM, they're right, I happen at 2AM.

Hey, I've seen Classics with 22.5" (and even 24.5") wheels, and they looked pretty good. Of course, they were Freightliner Classics, and those are the 2 standard rim sizes for heavy trucks.Any fool can piss on the floor. It takes a talented SC to shit on the ceiling.

Quoth sld72382 View PostI hate seeing those big "dub" wheels on the classics!
As for shooting trains, when Conrail was still around...it seemed that I never had a car or camera at the same time. The exception was when I took a photography class in college--Conrail's ex-Monongahela main through town was a few blocks away. I'd walk down there during class (we got some free time outside), and shoot locomotives, freight cars, and anything else. That would have been 1995-96, the NS "invasion" hadn't happened yet.Aerodynamics are for people who can't build engines. --Enzo Ferrari
