OO that uses 16.5 mm track is a British thing while continental Europe uses HO with 16.5mm track. However things used to be where each continental manufacturer did its own thing in the scale gauge ratio.

The correct gauge for 1:76 scale would be roughly 18.8mm, and in fact there are a couple of fine-scale British standards which offer this (EM and Proto4). OO track looks kind of narrow underneath British outline models. (The effect is even worse when you run Irish outline models on OO or HO track - the Irish standard gauge is 5'3").

I put a new Digitrax DZ125PS into my new OO scale Bachmann Ivatt 2MT today. I'd tested the locomotive on DC earlier and it ran very smoothly and quietly (very little PWM-induced "buzz."). It runs quite well on DCC also -- except at …

Ultra-precise scale OO track, called P4, is 18.83mm. The 18mm dimension is a little earlier and is called EM. The Rev. Denny said he had track width gages made to 18.25 mm to accommodate tight curves and locomotives with longer rigid wheelbases. …

This is what we are used to, and it works that was on our OO and N scale products. However, NMRA RP-25 only recommends a taper, and having spoken to a former colleague who is deeply into American HO scale we now realise there are ready to run models being produced without the taper on the wheels, which would of course cause the short circuiting ...

I am into O gauge and also collect 1/24 vehicles there quality varies greatly in the larger scale on all of the late models one has to watch carefuly. A friend got some old style vehicles direct out of China that look great in O.

I am sure there have been several posts on this subject, but thought I would poll members on the types of glue they use to put down track and roadbed. Over the years I have used various types of glue to put down track and cork roadbed. Suggestions would be …

Caveat: I am not responsible if you mess up your cv settings, if this scares you do not mess with them. But you cannot brick your decoder you can just set CV8 = 8 and it will reset your decoder back to factory default settings. Just some tips from programming these models for

I will be starting on an Athearn C-50-8 HO Scale Genesis model weathering project so SP photos are preferred but online searches so far have given me nothing. Thanks in advance!

Bachmann is doing the ACS64 in HO Scale. If anyone does the Charger in HO, it would probably also be Bachmann. For N Scale, possibly KATO. If you want to kitbash, look for Siemens "Vectron" models from Europe as a starting point.
