[billgiannelli]

what is code 110 vs 100?
I thought I understood what code 100 is but now I see code 110 on other sites.
is that used with code 100?
thanks
Bill

Sure it is referring to HO scale track Bill?  Never heard of 110, except for referencing voltage or a N/S route on L.I.
Can you paste here?

Code 100 is a rail size.
Code 110 is a wheel tread size.

[billgiannelli]

Ah yes!
That makes sense!
thank you
Bill

Bill, does your looking at wheel sets have anything to do with your other topic question about replacing the trucks on your tender?
What wheel sets have you checked out?  I have used Kadee, P2K and Intermountain (both 33" and 36")  successfully.

[billgiannelli]

yes it does!
Thanks for the info!
Bill

You're welcome Bill.

Thanks for jogging my memory Zeph   Only ever got the 110s (for the Kadee ones anyway).  Don't recall that as part of the descriptions for the P2ks or Intermountains.

Tender trucks will, by prototype practice, vary in type, size, as well as appearance.  I have "built" several tenders using Bachmann parts, as well as brass parts, and truck type; for instance, I have used 'drop-frame express trucks' on some of my tenders.  The one thing I will recommend is to use the same preparatory care that you would use on other trucks; by this I mean, check your wheelsets, if you have plastic trucks, use that wheel tool to clean up the axle bearing area, then use graphite, or another type pf dry lube.  I use graphite.  Also, if the tender is equipped with  plastic wheelsets, my advice is to lose them and get metal-your choice of mfgr-wheels.  If the tender has electrical connections (most do), then ensure the continuity is good.

Code 100 is a rail size.
Code 110 is a wheel tread size.

Wheel Code is Wheel Width in thousandths of an inch. Wheel Tread Width (size) is a different measurement.

Wheel Code 110 represents a wheel width of 0.110 inch

Why?  Was the Kadee link not enough, that shows the difference between Code 110 and Code 88 wheel widths

Jim;
Regarding those "88" wheels.  I have used the 'prototype" wheels, and am not crazy about them.  They look good, and to the manufacturer's credit, are very accurate.  But, I would rather the security of RP-25 or the like.  I know that I probably won;t have to  fish a train our of a tunnel because of those wheels derailing on my "expertly done" track.  How have you fared with them, or do you use them?

Me neither.  When I have bought Kadees, I have stuck with the 110s.  They allow for running on a wider variance of track than 88s.  I like all RP-25 wheels in general over non RP-25 wheels.  It's the way to go.
