Jose Munoz was asking about O scale models on the Magnorail System - I replied on my YouTube Channel klatchco56 in the following way.
Magnorail is scale agnostic - in other words the vehicles on top can be from z scale to HO. As to O scale, I would imagine that the vehicles would have to be reasonably light and freewheeling and would need a stronger magnet on the slider. Regrettably the bicycles are only available in HO scale. I will try an O scale vehicle to test out the theory - watch my blog on my website at www.magnorailoz.com.au or subscribe to this channel
Basically boats and canoes etc are easier as they actually contact the surface directly. A velour velvet on the crafts bottom will reduce friction. Once again a larger neodymium rare earth magnet should provide the “sticking” power but it is all about physics - the heavier the craft the more power and grip needed to move it. I would not recommend putting a fleet of O scale boats on the Magnorail System as it is powered by 2 x O rings gripping the track as the motor turns and too much tension by stressing the pulling power would make the system slip. However 3 or 4 canoes would probably work. I use Preisser models and adapt them with either MagnorailOz sliders or magnets in the topside of the hull of craft.
The canoes seen on the video https://youtu.be/IzE7jhDvOeU are in actual fact N scale models
Clyde has been involved for many years with the Magnorail system having built his own layout "Echo Lakes" featuring two concepts using the Magnorail System.
