I have a orginal Pargon Hudson I bought new. It was placed on the RIP track about 5 years ago. Have her running great again excpet it cannot pull more than 3 passangers cars in some sections of the layout.
It came with traction wheels and I think it is time to install them, problem I don't have a nut driver that slow. I think there was a tool when I bought the engine to get the drive nut's off but for the life of me I have no clue what I did with it?
I hope to buy just one nut driver becauses this is the first time in 10 years I have need one. Does anyone know what sizes I need?
Thanks for the coming answers.

Hey, Ken
I just checked mine and they used two different sizes: a 2.5mm or a 3mm depending on what kind of side rods the engine has.
Do you have a Harbor Freight nearby? Those sets of small nut drivers can be found pretty cheap. Maybe they have them? I know Radio Shack used to have them for sure.
If you can't find one let me know and I can send you one of my spares.
It will cost you a in the Diner!

For some applications -- and working with a nut on a return crank would be one -- you might prefer a flat open-end wrench to a nutdriver (which has to be kept roughly vertical with the nut and the degree to which it's been unscrewed hidden from view substantially). At these sizes the usual construction I see is a deformed metal bar with a plastic handle, and I believe some of the 'usual suspects' stores like Northern Tool and Harbor Freight have them in plastic-boxed sets at relatively low cost. You could always adapt a slightly smaller wrench with precise filing and dressing of the parallel 'jaws' to get a more exact fit to the nut flats if you want to avoid any potential marring or other damage to the visible nut.
Ed and Overmod thanks for the answers!
Ed I asked Larry about the Harbour Freight set I saw and he stated "I bought one and 2.5 MM is to big". But he did not state what kind of engine he was working on. That is the reason I posted the question. If you say it will work I pick up a set.
Overmod I will take a look at the wrench sets as well.
Thanks for the answer and I see you both in the dinner.

Can't argue with that...
The Broadway NYC Hudsons that have the roller-bearing siderods have a 3.0 mm hex. The older J1 models are, as you can see, 2.5mm.
Unless I'm confused somehow.
The Broadway Mohawks have a 2mm hex.
This is a nice set of nut drivers:
