Locomotive for ultra small radius?

[wazzou]

We all make compromises (model railroading is full of em), here is a decent photo (O&W 105) showing the hood:

Do you own one?
It's not really a compromise if it's literally the only choice.
I mean, it's not like we're comparing GG-1's or PA's here.
It's the only option and it isn't that bad, IMO.

No, I could not get past the hood. I wanted a small loco for a little industrial thing, but I ruled the Bman 44T out. I ended up buying a 70 tonner, as it is a pretty decent model.

So the turning radius or the radius of the hoods?

Exactly!

I have a difficult time believing there is much if any difference in the width of the 44T hood verses the 70T.
Isn't the mechanism and decoder essentially the same if not identical?

Maybe this will help with your lack of faith

I'm talking about the models.

Does anyone know what the minimum radius is for the Bachmann Plymouth MDT?

Here is a Kato chassis going around 2.75" radius :

I'm talking about the models.

The models are likely the same width but the prototypes aren't.  While the Bachmann 70 ton may be close, the 44 ton is not.

Using shop diagrams which aren't the best source, but can get you in the ballpark, the 44 tonner hood is about 54' or .3375" in N scale.

You said you measured 69" which gives a difference of ~15". There's lots of ways to look at it; .093", the width of a grab iron, 27% over sized etc...

Regardless, proportionally, it's pretty glaring (to me), it may not be to others.

Here's your guy.


Everyone knows that there are laws against running diesels on a Christmas Garden.  You need a bit of side rod action.

This is the ancient Atlas/Rivarossi 0-4-0 shifter.  It's got good tender pick up, and a cast metal boiler that makes it surprisingly robust.
They make regular appearances on the after market and usually can be had for around $50.
You might need a shot of contact cleaner and some gear lube to bring it back to life, but it will handle the tiniest of curves.
Looks good hauling short freight cars or old time passenger cars.
Highly recommended!

Exactly per my previous post... great minds. 😉

You didn't specify N or Z

No, I completely get all that, I'm just saying it's what is available, in fact all that is available.
I'm far from a Bachmann apologist. 
I own the Spectrum 2-8-0 (bought it from you) and the 44T, that's it from them.
If someone, someday makes an improved 44T, then I'll be more understanding of the Bachmann blowback.

my last post on this thread


the OP wrote "whimsical seasonal table top loop ... engine and cars that can traverse a ludicrously small radius, that would only be used for this"


the point that seems to get forgotten is there was NO request for the best prototypically proportioned locomotive.
the size of the hood is not an issue according to the information we were given
my only disagreement is that the size different is NOT an issue in this particular application.
if the OP was going for prototypical he would not have used the word whimsical and he would not be using that size of radius.
anyone's expectation as to how well the bachmann model meets their own criteria is a moot point from the get go.
