Difference Between Oo And Ho Gauge. ho scale to mm conversion chart Scale model conversion ratios This was because when HO was first introduced, the motors were too big to fit in a proper HO British locomotive, as the locos are smaller over here due to restrictive loading gauge, so OO was introduced as a compromise and has stuck around since, despite attempts to introduce HO to the UK back in. Taking all that into account then, there are some key differences between OO scale and HO scale, but with both scales using the same track gauge of 16.5mm, the temptation to mix and match items is overwhelming

HO is to a scale of 3.5mm to 1ft (a ratio of 1:87) OO is to a scale of 4mm to 1ft (a ratio of 1:76) Both OO and HO use the same gauge of track (the distance between the two rails) Those who model in OO gauge have the benefit of The Double O Gauge Association to help maintain standards within the manufacturing side of the hobby After HO, N scale is the most popular in North America

Just space your figures and vehicles out far enough so that. One can run HO gauge rolling stock on 00 gauge layouts, the track gauges both being 16.5mm, but the difference in scale will immediately become very obvious 00 Gauge 4mm to 1ft, 1:76 scale 16.5mm track gauge (inside track width) This is the most popular scale for British modellers and is probably the best supported in the industry with a wide.
OO vs HO scale The red coach on the left is built to Briti… Flickr. Many modelers start with equipment in this model train scale and a flat sheet of plywood for a simple and satisfying display, or layout HO and OO are actually standardized sizes of both scale and gauge (the distance between the tracks) combined
Comparison between OO and HO r/modeltrains. HO is mainly US and Continental Europe, OO is exclusively British What's the difference between OO and HO track and trains HO gauge, widely used in Europe, features trains with a scale of 1:87 or 3.5mm to the foot, meaning they're 1/87th the size of the real thing
