Mel, I don't have any background with any Rivarossi HO models except for the Heisler and the H-8. I have the newer H-8 that was offered for sale with factory sound (ESU) back in 2006, about the time Hornby bought Rivarossi.
The newer model, and I believe it's the one that Hrovje demonstrates, has traction tires on one axle, I forget which. This vastly improves the tractive effort.
I don't know the history of the tooling, either, but the Rivarossi Allegheny is a truly large locomotive, quite noticeably larger than a BLI PCM Y6-b and my Lionel HO Challenger. It appears to be substantially taller and more massive.
Keep us posted, the stall current and torque are pretty low on the Micromark #86529. Half that of a Canon EN22 or Mabuchi FS266SA. Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
mkepler954 Where can I buy a Rivarossi motor for a 4-6-6-4 loco. I believe the part# is P-245-073. It measures 1 3/4 in. including the flywheel. I've spent hours online but can't find one anywhere.

Sorry I overlooked a question related to foreing language site I linked.
For foreign web sites in language I do not understand I usually use automatic translation offered by Google, as explained by Simon (thanks). The site I linked is Italian version of ebay, i.e. language is Italian (which I also do not speak, but can understand within certain limits). I have this motor, it is quiet, works well but I did not install it. I bought two just out of curiosity.
P.S.
It seems this seller does not want even to receive any questions out of scope he already explained in item description. I wanted to send him a question if shipping to USA is possible, but it it even impossible to send a question. Sorry for that, that is a bad attitude when selling something on www.

mkepler954 I went to the European eBay site and the motor looks like a good fit but I have no idea how to contact them. It's all in a foreign language which I do not speak. Thanks for the lead though.

According to the specs your Allegheny has 8 ounces of drawbar, WOW! My weighted Rivarossi Cab Forwards only have 5.8 to 6 ounces. My Cab Forwards weigh in at 1 pound 3 ounces compared to your 1 pound 14 ounces.I didn’t see any mention of motor RPM for the Allegheny, the Cab Forwards are 5000 RPM so the Mabuchi SF-266SA and Canon EN22 at 6500 work out very good. Both the 266 and EN22 have at least twice the torque as the Rivarossi motor at less then half the current.I’m currently working on an AC-9 Kitbash from a Rivarossi AC-10 that weighs 1 pound 5.4 ounces and it has 6.8 ounces of drawbar.This is my fourth AC-9 Kitbash, it has a pair of Canon EN22 motors on a adapted Cab Forward frame/weight, I’m in the process of removing the cut up Rivarossi frame/weight and installing a Mel brass frame with a pair of new Canon EN22 motors.
The Southern Pacific articulateds are my thing, I rode in both an AC-9 and a AC11 as a teen and I never forgot them.

Mel,
yes, double shaft Canon EN22 would slip in, but I do not know if it has enough RPM for this locomotive, this should be checked first. But regarding dimensions, I think it would also be a good replacement.
I do not know what do you mean by "drawbar"? If in mechanical terms, it is a "snap on" plastic drawbar, while electrically, locomotive and tender are connected thru connector as usual (I am not sure how many wires - 6 or more - I do not want do dig the loco now, it is packed with other US locomotives).
I have Intermountain Cab Forward (third run, the only one without issues). While the detailing on both locomotives is on the same level, I like much more Intermountain internal design, it seems to me more robust, more solid than Rivarossi Allegheny. It is very heavy. I think more details are simply not possible on model locomotives, than is offered with these two.
Here are two reviews on Rivarossi Allegheny: link 1, link 2.
Spalato68 This is how my Rivarossi Allegheny looks like. It has two shaft motor, reminds a lot on Mashima 1833: Hrvoje

HrvojeWow!! That is much improved from the older Rivarossi locomotives! Is the shroud around the motor metal, if so the locomotive must pretty heavy. It looks like a double shaft Canon EN22 would slip right in.I’ll have to keep my eye out looking for a newer model of the Cab Forward.What is the drawbar on your locomotive. Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
If OP's locomotive has similar arrangement, then in fact any double shaft motor with dimensions close to 1833 could be used. The problem is, currently there is not a lot of possibilities in that range, except maybe Kato motor (excellent, easily available in the USA), or some motor(s) from NWSL (do they have some?). I did not mention PPW, because of, how to say...weird pricing, maybe?
I found replacement rotor on ebay for double shaft Rivarossi motor, maybe this could help. Just 3 GBP. Seller mentioned "full motor also available", maybe a complete motor is also available.
Hrvoje is correct a picture would be a great help. And as I’ve not seen the inside of the newer Rivarossi locomotive with a flywheel, is the motor single shaft or double shaft? Is the motor in the cab or between the driver assemblies?My older Rivarossi articulateds have the single shaft motor in the cab from the factory and I do my thing using a pair of can motors (Canon EN22 or Mabuchi SF-266SA) driving the driver assemblies. Canon EN22
Mabuchi SF-266SA
With the newer Neodymium magnet can motors you can add weight to the boiler for more traction. By adding 10 ounces of #8 birdshot to my Cab Forwards it increased the traction from 2.8 ounces (factory) to 5.8 ounces of drawbar.
Also the new motors draw less current and have double the torque of the old factory motor.For those that have broken Rivarossi Cab Forward or Y6B frames it is possible to make a new frame from brass.
A picture of motor and/or item number of locomotive would be helpful. There is one motor for Rivarossi locomotives offered on ebay, you can ask if shipping to USA is possible (and how much, if yes), motor itself is very cheap (5 poles, iron core, 4,55 Euro).
When Gulf Manor Hobbies went under that was the end of Rivarossi parts. I’m not familiar with the newer Rivarossis but you will have to find a can motor that will fit. You might try Northwest Short Line.The Mabuchi SF266 motors work out nicely in the older Rivarossis (no flywheel).Maybe someone that might know what RPM the newer Rivarossis motors are will chime in. The SF266 is single shaft 7000 RPM at 12 volts and should fit.
