Weekend Update 3/17/24

That article on the rail gun was neat to read. I inspected the preserved gun at the Washington Naval Yard a few weekends ago. I knew the Germans had built some in WW1, but I had no idea the US did too until I stumbled upon it.

That looks great, Reese. Can you post a closer picture of the headlight? And how fragile is it?

It's not the most fragile thing I've printed, but I am cautious while handling it. I broke one off earlier in the build and had to replace the smokebox.

Progress on my ATSF 2-10-2 build - Adams shell (Drasko)


Kato Mikado mechanism stretched



I need to extend the weight so the shell will fit and it will also hold the worm gear in tightly!

one of the rare Puddington Valley cars was spotted passing thru New Lisbon on the Modutrak layout at the Rockford Il. NMRA show this past Sunday

draskouasshat: I don't know if it is a problem with my 3d printer or my 3d software, but I don't seem to get ANYTHING that looks that good. I'll be watching this build. Excellent work!

We had the N Scale Modutrak layout set up at the Rock River Valley Train Show in Machesney Park over the weekend.

This was our most ambitious layout ever covering 40 x 60 feet in a serpentine configuration. 53 modules (many new) figured out to somewhere around 16 scale miles of track.

Never heard of "M" until you mentioned  it here.

Probably because that's what I called it, because I never heard of anyone modeling trains in 1:300 scale before.  As it works out, 1mm=1foot, so I thought of "M for millimeter".  Good as anything I guess!   I guess technically it's "Mn3".

The raison d'etre is that T-gauge track--3mm gauge--works out to be 3-foot gauge in 1:300 scale, so it ties in with my T-scale modeling.  And there's even T-gauge flex track that has longer ties (so I guess I'm not the first to try it, just the first I've heard of).  The added size between 1:450 and 1:300 is helpful as well.  On a whim, I may try modeling a standard gauge M scale, but I'll have to make my track (4.68 mm gauge).

I completed all the rough work on the turnouts for the Cadillac shelf.  It is a real schmorgesboard of different turnouts to make it flow as  nicely as possible.  A #8 24/18 curved, a #8 wye, 2x #6, #10, and a code 40 #6.  I had a fixture for the #6s, but I got pretty comfy with the paper templates and track gauges.  They all operate smoothly with a single truck, im real hopful for whole trains :0

I still have to isolate the frogs, attach feeders, and drill the throwbars before I can call them done.

Thanks for the explanation  So you are the M scale pioneer.

Thank you john. these will be for sale shortly! need to get the tender done first.

M Scale might be already taken:

"Recently, NMRA proposed some additional scales as standards. The additions to the NMRA list are 1-1/2 inch Scale [1:8], M Scale [1:13.5], F Scale [1:20.3], and A Scale [1:29]. They represent the latest trends in Large Scale modeling practice but sadly, they were never adopted as standards"

Might I propose HN? Half N?

Outstanding work.


A small query.  If 2mm to the foot is 1:152 (2mm Finescale), should 1mm be 1:304?  Or is my math(s) awry?


How about V for 'very small' unless that's already taken?

It should be. Then he can just call it 1mm.
