I'm a middle school math teacher. This last year I began to use model railroading as a vehicle for engaging my students with fun, interesting and educational activities that have vivid connections to meaningful real-world themes.

Here is a link from a FB group I am a member of.

Hey guys!

I can't seem to find a lot of info about motor conversions....

My question is.

What size are the shafts on the athearn hex flywheels, for the life of me i cant find any info on the size, not even on athearns site. The motor i have is a Kato HM5 so that has a 2mm shaft.

Thanks
Nick.

I'm going to be posting only photos from what was formerly known as the Contest Room, as well as a setup of locomotives and cars that Jerry Krueger had in another room.

Photos coming in the comments.

So this weekend I did the roofing, was a bit tedious, but in the end it came out good and I’m pleased so far.

First image is a sheet of corrugated roofing marked out with an ultra fine sharpie. the point of the sharpie fits well in the grooves. If you find your cut point ends up on a hump instead of a groove, flip it over and you’ll be in the groove. No pun intended. Lol

I was fortunate to be able to interview Doug Nagel, who created a series of modules replicating the Somerset Power Plant and it's rotary car dump including scratchbuilt rotary couplers.

Someone asked about what was new in the area of DCC sound. We're going to have a first look of the SoundTraxx Soundcar system coming up in a future issue, and I was able to interview Norm Stenzel of TCS regarding their upcoming (now in Beta) WOW Diesel sound decoder -
