I received a proto 2k USRA 2-8-8-2 as a gift:yep: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:cry:.
Any help would be greatly aprichiated. Thanks:

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.

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...

The Q2

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.

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.)

The HH-1 is almost complete. Decals are on and I am waiting for a missing part from life like. Then time for weathering as soon as I fix my air brush (I dropped it breaking the glass paint cup and nozzle)and add a coal load. I will post pics when It's finished.

Pennsy did share a lot of parts (including boilers) between locomotives, but the Q2 and J1 boilers weren't an example of that. The J1 used a Lima designed boiler with a "conventional" radially-stayed firebox crown, whereas the Q2 (as was the case with almost all Pennsy steam) was a Belpaire type - this shows up as the "shoulders" on the boiler ahead of the cab.

The Belpaire made for a more a more efficient firebox, but wasn't as easily constructed as the radial stay type - which is why virtually all American steam used the latter.

exception

The Great Northern also was a Railroad that appreaciated the Belpar firebox.
