This one is almost readable -- maybe 105 inches?

Someone must have the Staufer book of C&O diagrams.

You sure do come up with some esoteric questions.  You seem to know more about the locomotive than anyone else.

I have been a railfan for 60 years and have picked up a lot of information in that time. I think the boiler was 102 inches and the locomotive had poppet values. Gary

Was it a proposal to Nickel Plate Road perhaps?

102" for the smaller 2-6-6-6 from Eric Hirsimaki's book, Lima The History, page 224.  Other tabular specs at this location, no diagram.

feltonhill, glad to see you back.

The 'smaller' proposal was pretty obviously a design for railroads not interested in union-overweight locomotives, but even with a scaled-down version of all that steam-circuit piping it would still be on the heavy end.  I'd be interested to see if the spec included Timken roller rods (like the ones on the last N&W As) and the full type-C continuous-cam valve gear as for the 4-8-6.

I'd suspect that the Nickel Plate didn't have the siding length for 'Berk-and-a-half' consists.

Yeah.  Sad.  By 1946 everybody was diesel happy.  With well noted exceptions of course.

Actually, HOORAY! The economies of dieselization (mainly in shop personnel and facilities) enabled the railroads to survive - and none of Lima's designs would have made any difference. As a matter of fact, at a time when the average freight rolled at 20 mph and the railroads were happy with that, Lima was chasing a market that didn't exist with designs optimized and running most efficiently at high (for the period) speeds.

Thanks for the notice, made my day!! I've been lurking and keeping a low profile for a while, but hope to get back at it again.  I think age is creeping up on me a bit.

I am happy to see you post again.  I just turned 70 (late June) and the slide has been dramatic in just 10 months.  But, we're both on this side of the turf, so not bad. Stick out tongue
