I think it may BE a Ruby... (or at least reverse engineered from one perhaps? Sure looks like one to me in those videos, no?)

Probably from the same maker? That vid is old, dating from the brass Q details from a few months back....

Not a Ruby, but it certainly looks like Accucraft tooling from their elec 8 Ton Porter.
This Bachmann Porter is a nice looking engine, I'll have one of these!

HMMM......

Looks like different drivers, different cylinders, different driver spacing, different linkage........but maybe that's just me.

I agree, I see nothing in that anything like Ruby, its all new parts, it may have engineering concept similar to Ruby, but thats about it. It way better proportioned that any of the Ruby variants - and is of an actual prototype.

It looks to me like the result of something the guy who left AccuCraft might have had falling into his briefcase when he left them, and then pulled out when he walked through the doors of Bachmann's manufacturing facility.....

Whatever, if it can be made to work like the 'Ruby' can be made to work - and looking at the video it certainly looks like a controllable runner to me - then I'm good with that.

The hobby benefits.

Well, running with the smokebox door slightly ajar so it doesn't whistle... ;)

I wouldn't be surprised if it's made by Accucraft, or at least in conjunction with them. While different enough from the Ruby in terms of proportions, the construction is virtually identical. It's the same boiler--down to the two-tone paint and smokebox door. Everything else on it is at the very least mechanically identical to the Ruby, if not physically so. The crosshead guides are a nice plus.

Here's Accu's electric Porter for comparison:


Looks like a very attractive melding of the Ruby and Porter. I have to say "about time," as I've always felt Accucraft was short-changing themselves by not coming out with a reasonably detailed loco based on the Ruby components. It would be nice if they painted the cylinders on the production loco.

Later,

I used a program called "Raildriver ScalePrint" (purchased from Raildriver.com) to scale old photos when I built my Ruby - Mason Bogie a while back. (Great program!) If we assume that the Porter in the picture is built with Ruby parts then the cylinders measure 1.104 inches from bottom of cylinder to top of valve. I know this because I have a loose one to measure. So I scaled the photo using that measurement, and the boiler scales to a 1/4 inch smaller(1 1/2 inch) diameter than the Ruby boiler. Using a picture of an Ida as a test, I did the same thing and the boiler measures (1 3/4 inch) correctly. Also the drivers scale to a smaller diameter on the Porter picture. So the proportions do not match up with the Ruby/Ida proportions. Here are the scaled pictures.






So I really don't feel that the Porter is built with "Ruby" parts.

Well done Larry, just confirming what I can easily see with the eyes, not to mention boiler height and so on. Yes, uses Ruby engineering, but different sizes, different proportions, all new parts.
and much better proportioned overall.

They arre just using the same factory that Accucraft trains uses, Just as the guy in the UK that commissioned the 4MT I think. BMMC built it for him and its not sold through Accucraft or marketed as Accucraft.

I would of hoped that they didnt use the 3/8" cylinders though, its going to have the same running speed and no low speed. Nevermind still cant makle grades. I bet though the Accuycraft 1/2" cylinders on the Forney can be swapped out thoguh.

I do like they used a smaller boiler, i was just talking to Ada yesterday that they should make the Porter in steam. My thoughts were to convert one and keep the orignal cylinders and use a small 1cyl geared to the wheels like regner. i dont want to loose the charm of the small cylinders nor the boiler. with the gearing you can run as slow as you want up grades and pull too.

If they get it out, id probally buy one, after I see it run of course.
