N scale NYC 999

[Dreyfusshudson]

Even on ho, thete's only brass model.
Did someone tried to make it, maybe modifying model power 4-4-0?

[randgust]

I got asked to investigate it as a custom build and was sent parts.

I still have it in the Pile of Great Intentions.

For a while, you could get a driver set from the Hiawatha 4-4-0.   Appropriate sized drivers from Fox Valley, but then it turns into another swirl on everything else beyond that.

When I built my PRR 4-4-0, swapping drivers on axles proved to be beyond my skill set, could not get them properly square or quartered.   Mark Graulty"narrowminded" had to do it for me; that was Atlas 4-6-2 drivers mounted on Bachmann 4-4-0 axles.  Difference between a kitbasher and a true machinist.  Mark hasn't been in contact for a long time, or on this forum.

It was also a lot easier when you could get steam details from Shapeways, Details by Eric, RLW, etc.   Now it's back to where I was in the 70's, finding junkers to hack up for parts like a grave robber.

Going to change its wheel with Dapol's a3/a4 spare.
Also, I obtained its blueprint.
I should use model power than Bachmann...

Would youbshow me your PRR 4-4-0?
I'm curious about it

[Dreyfusshudson]

I compared with blueprint and model power 4-4-0.
Because of its tender, model power is slightly long.
If I get some modification(milling down dome, change its shape...), at least I could make preserved version of 999, although it is not original 1893 version.

With Marks help, this project was an outstanding success for appearance and performance.  Certainly not every project is, trust me.

https://www.therailwire.net/forum/index.php?topic=48871.0

And as you can see, this turned into a team project from the forum, both for criticism and parts and ideas.

I've done two tender-drive gearhead projects like that and both were extreme successes.   Because of the enormous drivers and high-speed reputation of 999, getting low speed is probably not an issue, but torque might be.

But you will have the same problem that any given 4-4-0 in model form has a relatively short driver wheelbase and the lead truck is along for the ride, so ANY irregularity in the drivers, frame, rods, or running gear that makes a wobble or hitch gets magnified.   I tried to ignore it when I did the drivers myself, finally threw in the towel and asked for help.

Those Fox Valley Hiawatha drivers appear to be the biggest ones I've ever seen in N, BTW.  84" prototype

Base question.  The version using during the speed record, or afterwards when used in regular service?  86.5-inch vs 70-inch drivers.

Going to make preserved one.
FVM hiawatha is so hard to obtain it.
Maybe Dapol's 1/148 wheel could be alternative option
