come on you know you want to buy it , is it proto or riverossi ??Those look real good.
What would be the minimum radius they would need on turns?
Even tho I'm not doing that era, my LHS has a 2-8-8-2 , in the used area, was thinking about purchasing it. (ho scale)
talked to some guys running a local club, sounds like there are not too many around here doing steam,
Hmmm, I have some articulated loco's somewhere. Unfortunately I have no idea where except the Z5 which is in the safe, and the Z6 which is "in the mail". Moving last summer really scrambled my inventory, so I couldn't drag them out for a pulling contest if I wanted to.i was at home & bored so i dragged out some of my big steam & ran it on a strip of track, since sat my son & i are going to run some of it at the club
I have a question about those great looking locomotives. Are the rear locomotives free to pivot like the front, or are they rigid like the prototype ?
On prototype articulateds, whether Mallet (compound...usually the rear cylinders run at higher pressure, then the steam is sent to the larger, lower pressure front set before being exhausted out the stack) or simple (both sets of cylinders running at the same pressure), the rear engine is fixed to the boiler. Only the front engine pivots, and the pivot is between the front of the rear frame and the back of the front frame. There were several much older types where there might be another arrangement, but those are smaller and much rarer.
The advantage of the articulated was to be able to negotiate sharper curves than large fixed-wheelbase locomotives, yet be able to generate considerable tractive effort and weight distribution.
The only articulated I have on my layout are two that I kitbashed from Mantua 2-6-2's and various spare parts. I was unable to rig a transmission to the front engines, so they just go along for the ride. By using traction tires on the powered rear engine, they will pull a fair amount, but aren't the best at staying on the track. Although they are "simple" articulated, unlike the few GN/C.B.&Q. T-1's and T-2's, which were compound, they are neat-looking critters that I'll occasionally run pulling coal or iron ore drag freights. They can NOT outpull my kitbashed Mantua 2-10-2's and 2-10-4's. In all of these, I replaced the motors with Canon coreless ones, so low-speed performance is pretty good. As with the era I model, 1st generation diesels are taking over a lot of the workload.
The Z-5 had the largest firebox of any locomotive. This was to burn low grade Rosebud coal. It was so big that Alco hosted a dinner party for 12 RR dignitaries inside of it. At the time it was the worlds largest locomotive and Alco wanted to show off. I believe only the DM&IR M4s were larger.A Z-5 is the Yellowstone class locomotive, a 2-8-8-4.

You know I know you're right
not sure if it was proto or not, it caught my eye, (my financial planner saw the price lol)
talked to some guys running a local club, sounds like there are not too many around here doing steam, so I'll find some time to sneak it in the house
A few years ago someone posted that they had done that. Someone didn't believe them so they posted pictures. I can't find that thread now. They actually had 26 of them. Don't know which they had a duplicate of.yea i have to admit i have the articulatd bug im trying to collect all the H.O. scale BIG BOYS with in reason lol brass & trixs are a little outta my price range
all i can say is BEAUTIFUL LOC , how much my i askEarlier I said the Z6 was in the mail. Well it isn't anymore. It arrived today. My newest motive power. Too bad it is sitting on the only piece of track I have available, so not much chance of running it. The NP had 21 of these, delivered in 1936 and 1937. Along with the follow up from the 1930 Four Aces Northern 4-8-4 class, the Super Steam Era had arrived.
if your local store where its at has a layaway plan thing you could use that....pay it off a little at a time so the CFO of your family doesn't see it.....just saying....not like i am telling you to hide it.... hehe
