Weekend Update 11/22/20

Finally made some progress on my layout. The construction of the first building is done, just needs detail painting, and the road is taking shape. More in the Queensbridge Road layout thread.

Love that crane!

Wow.... OK, so that's probably the best stock 0-4-0 drive I've seen.   Is the Thomas Bachmann 0-6-0 built the same way with the same drive reduction?

I didn't buy Thomas and the parts diagrams aren't up yet. Thomas doesn't have any cylinders...

The M&O Signal Department is starting to upgrade the plant ..










Files are HO by Sirswitchalot on Tinkercad converted to Nscale (54% reduction)

Only the front driver is geared (brass gear) and between that gear and the worm (brass) are 2 (plastic) compound gears.

Impressive!  That insures the even at full throttle (which kids seem to like running at) the model will run at reasonable speeds. Right?

Same for Thomas

When has that ever stopped you.

Personally, I wouldn’t paint the ceiling black. It won’t typically be in your line of sight when viewing the railroad. I would install some trim where the valance meets the ceiling to address the light leakage, but that’s about it.

I did get some 1.25" black foam tape that I'll run as a trim to prevent light leakage.

The reason I'm painting it all black was for the (lightbox) effect, but also I'm ~6'3" and the ceiling is ~6'5".

It *is* right there above my eyes, not ideal but it's best I can do.

The prototype for Thomas had inside cylinders and rods.  The British designers loved them, as it made the locos look "neater", without all of the mechanical stuff showing.  The shop forces hated them, because it made them much harder to work on.

I doubt that many, if any, such locos were built in the US, although we did have some 3-cylinder designs with one center cylinder.

Here are some photos of the new Bachmann chassis:

I'm told Percy is mostly a Avonside 0-4-0ST. A lot of the other characters do have a prototype.

Here is the size of the Tomix chassis:

The new Bachmann chassis drivers are .291" dia and .601" WB.

That's darn impressive.  I see it's a coreless motor, and I like the flyworm.  I was thinking about what good bones this might provide for a serious 0-4-0, which is a diffiicult enigne to make run well.  Are the drivers gear or rod driven?   The pickup seems to work really well, so I assume no traction tires (I hope not!)

[Chris333]

Front driver is gear driven, rear is off the rods. There are wipers for pick-ups, but they seem to work well. No traction tires. No counterweights on the drivers. And since it's "Thomas" they are about $75 bucks.

[Chris333]

A quick photo. It shows the drivers, the motor, wipers, and the 2 plastic compound gears.

[mmagliaro]

I like that neat trick of two offset double-gears to get the speed reduction, but still keep the worm centered over the middle of the frame.  I am sorely tempted to get one of these just to experiment with that chassis.

Couldn't help but notice the excavator on the roof top of one of the row houses in the bottom left corner.  Was that intended to be there?  Just wondering where you found the prototype for that

Brought the Potomac a bit closer to completion...
Using a Trix K-4 headlight mount and a desperately contorted LED, I was able to get light to the high mount headlamp.



Of course, the only way to see it on a DC layout is with a tracking shot!  Also got the bell installed, which was gleaned from the OEM smokebox.



I still have to patch in the walkboards at the smoke box sides, and decide whether I want to change the cab... The cab overhang of the original isn't a match to the WM's All Weather cab, but it helps disguise the spread between the cab and tender, which I need for my ridiculously tight turns.  Maybe on the next one...   The finishing touches for this, I think, will be the proper cab number and a few other distinctive decals to make it ready for prime time.
