Heavy PRR Steam

e-paw · 04-13-2008, 10:10 PM

I received a proto 2k USRA 2-8-8-2 as a gift

and want to letter it for the Pensey (who got them from the N+W).The model comes with 2 sets of cylinders. A standard and modified low pressure set. I don't know which is correct for the 1940's

. I could only find 2 pics of these engines and could not tell from them

.
Any help would be greatly aprichiated. Thanks:

. It looks like I have to switch them out to the modified version and alter the pilot. thanks again.

Theres just something about those huge brutish looking compound cylinders i like

I am so glad that you posted those pics of your model. I would love to have one but my layout radius would not allow it. Great Job, Big heavy PRR steam is the best.

The Q2s. Anyone know the history of this type Pennsy steamer?

GN.2-6-8-0 · 05-09-2008, 01:15 PM

built in 1944-45 the Q2s were the most successful of the Duplex locomotives built by the Pennsy at their Altoona shops.
Using the same boiler as the J1s the 26 Q2s were able to output 7,987hp
but were gone by 1951 because of their higher operating and maintence cost's compared with the J1s........ and of course the diesel's were the wave of the future...

bigsteel · 05-09-2008, 01:16 PM

i have no idea what that is ( a 2-4-6-4?) but it does look like the front truck in the second pic has track problems

--josh

EDIT:looks liek we were typin at the same time GN nice pic too.

toptrain1 · 05-09-2008, 01:38 PM

The Q2 is a 4-4-6-4. Duplex. This means it has a rigid frame, not articulated. Instead of a 4-10-4 with only 2 cylinders driving 5 driver axles a aditional 2 cylinders were added improving traction and horse power. The Q1 4-6-4-4 was first made. The Q2 was a improved version with better tracking qualities and more umph applied to the track.

rekline · 05-09-2008, 04:29 PM

Wow what a great example, who made it?

toptrain1 · 05-10-2008, 09:41 AM

My model is a early brass by Imperial Models. It is a good runner. e-paw did the paint I lettered it. toptrain

The odd thing about the Q2 and the other duplexes... Even though they weren't successful, when several companies proposed new steam after the oil crisis, one design was a duplex. In fact, a 4-4-6-4 based on the Q2, but with a condensing tender like a South African Class 25.

It's so nice to see what you folks in the colonies have done with our Mr. Stephenson's basic design concept. One might almost be inclined to forgive the minor misunderstanding over the tea tax.

(I just love S-T-E-A-M ! Thank you for posting those pictures.)
