Would stretching it 10" N scale really be noticeable? That would keep the height and width correct at least. My calculations come in at .0625 or 1/16 or an inch. Then again up sizing proportionally shouldn't be all that noticeable either.

I was wondering if that the new boxcab was the same as a dim memory of an old etch, seems that my question was answered. Liking the recent progress, the LIRR is a gem.

Scaling up the whole model is much easier than just stretching it one way. And yep the new one is the same size as my old etch since I popped the old model in my scanner and traced it  ;)


Printing 3.27% now to see if that works.

Thanks guys.

Success.

The bottom one is 3.27% larger, you can barely tell and now the chassis fits without any cutting.


I could have milled the chassis to make it fit, but I wanted it to fit a stock chassis. Someone other than me may want to build one of these and wouldn't be willing to mill the chassis down.

Math question :facepalm: or am I even looking at this right?

The coupler situation on the 44 tonner is tight I can make the boxcab to scale and make it fit the chassis. But there is like no room left for couplers.


Maybe using the MTL short T-shank coupler would work?  Like the one used on the first generation Atlas Shay?  I don't remember the coupler part #.

Here shows the coupler situation. On the left you can see there is barely enough width to fit a 00-90 screw into it. The right is a 1015 coupler.


It might look like the coupler is sticking way out.


But the pilot sits on top of the coupler box.


Pilot is just sitting loose here. The gap will close when I glue it on.


And here is the roof with the mufflers and radiators.


And I knew the whole time that the "fuel tank" area of the 44T would need cut out so I guess someone will be milling the frame anyways  :P

Also the Bachmann 70T has larger dia wheels that are correct for the boxcab. Trucks are the same so just order new wheels. But Bachmann lists the 44 and 70T wheels as the same part number when they are clearly different.  :facepalm:

And back to the shorty Long Island cab. I'm not a modern diesel person. Is there a 6 wheel Kato truck out there that has 6mm wheels and a 18mm WB on the two outside wheels?  I would like to make up another chassis by adding a motor to a single truck with the center wheel removed.

Yep, that’s it.
Going to have to dig into what 0-8-0’s or 2-8-2’s, Japanese or European might have “close” driver diameters and wheelbase.

A bit off topic, but maybe something like this?

I wonder if that is the same as the coupler MTL used on their own FT- which is a very tight fit?  The FT coupler has a custom bracket to allow attachment to the FT chassis, but if that were cut down, the remaining coupler would fit in a lot of places too small for a 1015 (etc).  I could not find it in the coupler listings, but the FT frequently makes it into MTL train sets, and to repair some FTs a few years ago, I was able to acquire some couplers  via customer service with an assist from Joe.

The 1021/1022 might also work, if the mounting tab at the back can be made to clear the trucks, or just be removed and the coupler box glued or otherwise attached-

Thanks Thomas.  I’ll see what information I can find about those.

If would like to get an idea about what the mechanism of that 2-8-2T loco looks like,  check out the parts diagram: https://www.fleischmann.de/en/printpdf/pdf.html?id=242978

These are the MTL couplers I was thinking about for the boxcab.



The 1131 is a retrofit for Bachman Rapido coupler type they used in the '80s.  It includes a coupler box which snaps into the Bachmann mounting shelf, but you would need to fabricate (or 3D-print) your own mount

A few simple mods to the design and you have an electric from Iowa.

I have Coos Bay Lumber #11 plans. Is that what you wanted?

@Chris333 - NICE WORK! When I did my CNJ 1000 I got hung up on the couplers too. I went with the 44 tonner mechanism, which runs sweet, but the truck swing is limited by the back of the draft gear. At first I was using 905s with draft gear cut to fit. I've since switched over to true scale couplers on my rolling stock and not gotten back around to getting the 1000 working again.

I bet those grab irons were fun  :scared:  I thought about doing that, but just tried to match mass produced freight car grabs. Mine do each have a mounting lug with a bolt that are so small you can't see them.



CNJ 1000 had the side sheet metal that wrapped up and around the roof. Later versions like Erie had used a separate sheet for the roof.
