Any idea what I could use to model this 2-6-2?

[mmagliaro]

The axle spacing, driver size, valve gear and cylinders from the Bachmann 0-6-0 all look much closer to the 1077
than the Atlas 2-6-0.  And the atlas 2-6-0 has those filled-in non-see-through drivers.  I think I'd have to vote for the
Bachmann on this one.

One physical thing I see that will be tricky is that there really is no room out in front of those cylinders to fit a pilot wheel.
The pilot beam is going to have to move forward.  But the pilot on your prototype juts way more out in front than the Bachmann's anyway.  Since that will have to be a newly-made part, it will end up sticking out far enough to allow for a wheel in there.

Max,
 My loco in the picture has a different pilot on it.  Don't use it as a reference for that. I moved the pilot back about an 1/8 and replaced it with one from a MP loco to match the 0-6-0. The one they come with is stretched to make it work on the 2-6-2.

Aren't the Bachmann 2-6-2 and 0-6-0 basically the same loco?

[SkipGear]

Yes, they are exactly the same loco. The 0-6-0 comes with a different tender and no pilot or trailing truck. Otherwise they are exactly the same.

I built a little 2-6-2 Logger from the Bachmann 2-6-2, Although it looks heavier than what you are shooting for. I'm only going to post one picture, because I wrote an article about it for the N-trak Steam Add. a few years ago.

I would start by getting some measurements on that Bachmann engine's driver diameter, driver wheelbase, and overall length.
It looks a little big to me, compared to the engine you are building.   Although it's overall proportions look to be about the same.

[randgust]

The Atlas 2-6-0 has a 11' 0" wheelbase from front axle to back axle center, 7' from front axle center to lead truck center.  Wheels measure .273, my math says that's 44" or there abouts.

So you closer than you think to the basic Atlas chassis.   

Remember this is a Micro-Ace product imported by Atlas, you might discover something rather similar with the right valve gear and cylinders.  And your main rod goes to the back driver instead of the center one.    I wouldn't want to have to transplant that part.  Micro-Ace is very, very Japanese but the quality is right up there with Kato.

Hmmmm.   Look at this one..... http://www.newhallstation.com/images-lib/microace_n_scale/MA-A6308/

Found some specs but it's still bigger:  http://www.steamlocomotive.com/locobase.php?country=Japan&wheel=2-6-0&page=jnr

Thanks for posting those numbers and links Randy. 

If the Micro Ace C56 is built to prototype dimensions it would be about 12.5 between the front and rear driver centers (1077 is 9.') and 8' from the front truck to the first driver.  Not that far off really.  I can hide the 3'  of extra length.  Running like a Kato is a good thing!

Craig, that loco is areal cutie!  Seeing the drawing I now see why you would like to model it.  I wonder if some of the models of European locos would be a good starting point as most are smaller than US locos.  Maybe using a chassis from one of the tender locos.  To me the Bachmann 0-6-0 boiler seems way too long. The loco you want to model looks much stubbier.

[PGE_Modeller]

I just measured my Bachmann 2-6-2, and came up with the following dimensions:  driver diameter: 0.318" (51" in N scale); driving wheelbase: 0.828" (11'-0" in N-scale).  I can't measure the lead truck - first driver distance as the lead truck is missing from my loco at the present time.  Trailing truck needs to replaced, anyway, so that measurement is irrelevant - other than to say that the trailing truck on the Bachmann 2-6-2 sits WAY too far back!!  Visually, a major difference is that the Bachmann has a straight boiler while the 1077 has a wagon-top (tapered) boiler. 

The Bachmann is, however, a decent stand-in (when fitted with a sectioned and shortened Atlas IHB 0-8-0 tender) for Ocean Shore Railroad 9 & 10 which became Pacific Great Eastern #s 4 and 5.

Cheers

Interesting.  So the Bachmann has slightly larger drivers than the Microace (and the prototype) but they are closer together than the Microace.  I wonder how hard it is to lower the boiler?  I think it would be very difficult to get it low enough but that is a very unqualified thought since I don't have the loco.

Those videos Randy linked to are really cool.  Maybe a tender mounted motor is the way to get this done?

Aren't the Bachmann 2-6-2 and 0-6-0 basically the same loco?

The B-mann "Prairie" is really a USRA 0-6-0 with idler trucks added (hence my use of quotes around "Prairie".  If you look at the trailer, it does not look like it belongs).  The prototype
 USRA 0-6-0 came with the USRA switcher tender, which B-mann includes on its "Prairie".  B-mann's version of the USRA 0-6-0 comes with a slopeback.  No USRA original locomotive ever had a slopeback.  According to a source that I trust, no USRA 0-6-0 copy ever had a slopeback.   In fact, he told me that none of the roads that played "musical tenders" with their steam power ever fitted a slopeback to any USRA original or copy.   It is no big deal, anyhow.  If you want a properly performing version of this locomotive, you will need to swap out the stock tender for a SPECTRUM.  The SPECTRUM tender is all wheels live and has needlepoint axle pickup.   The stock tender comes with one truck live, only.  Further, the design of that truck puts a tremendous amount of drag on the locomotive.

Make the tender swap and it renders a locomotive that has superior performance.  I have one so modified that performs the most demanding task on my pike and does so with no problems.

Peteski, any suggestions for a place to start looking for. European loco? I don't even know any brands.

Edit:

Research showed Fleischmann and Roco as possibilities but I couldn't see any in either company's line up that was small enough. Beautiful models though.

[mmagliaro]

The correct wheelbase of 9' would be 0.675" in N Scale. (a little over 5/8")
Both the Bachmann and Atlas locos have 11' wheelbases.  That's 0.15", or more than 1/8".

This is the thing that's not looking right to me.  The prototype has the drivers snugged up close to each other
in the center of the engine with the pilot and trailing wheels kind of hanging "out there".  That's
a big part of the look.

But both the Bachmann and Atlas engines have spread-out drivers that I think give the whole
thing a more "gap toothed" look.  The Bachmann drivers are too large, but I would argue that since
both engines are the same wheelbase (11'), larger drivers at least put them closer together.
I would probably opt for that, especially since Bachmann's drivers has see-through spokes, not those
solid-wheel looking things that the Atlas has.

I know the Atlas/MicroAce engine is a good runner.  I have one.  But the new-age Bachmann 0-6-0 is still pretty good
and there's a lot to consider with the appearance here since either one is going to be a compromise.
