Let's see your Great Northern Steamers!! Helena, MT is where Otto Perry captured this oddball wheel arrangement 2-6-8-0:
I'd love to hear an audio recording of this engine. Am wondering if it had a special sound... Boxcab E50
Compound or Simple Looks like a compound engine because the front cylinders are larger than the rear. OTOH, that may just be the appearance. I always considered the compounds types as luggers for the heavy stuff and the simple engines as being faster.
You may be correct.. GN rebuilt some if not all of their compound 2-6-8-0's into simple engines during their careers.
Pretty danged powerful, 153,000#.. The 'Big Boy' UP engines are listed at ONLY 135K... The Virginian engines are just sick... 200K #?!? http://www.steamlocomotive.com/misc/largest.shtml
Yes. It's a compound. With those stacked cylinders, isn't this a double compound? The front cylinders could be larger. If it's re-using (lower pressure) steam. Then it needs greater volume. Boxcab E50
Otto Perry bagged a 2-8-8-2 at Marias Pass in 1939... These monsters outmuscled about 20,000# higher tractive effort than a UP Big Boy!!
Close enough in Z!:teeth: Clean of the roof fans and put the GG1 pantographs on, and different grills on the sides. And tada, a Y1a!
I can only imagine what that thunder felt like... From the largest GN steam, to one of the smallest: Otto Perry:
