Tomy Super Rail System

I have no idea of the scale for certain, but my gut feel is that it is probably closer to HO scale (or similar to Tomy PlaRail). The track etc... tends to look more realistic so I wonder if it was a Tomy attempt to bridge the gap between PlaRail and Scale models. Of course this is all conjecture on my part and it seems all the listings are pretty old examples so it could have just been a failed experiment or something on their part.

I don't think it is PlaRail Advance scale though as that is nearer to N scale models, just not quite as detailed - although they are definitely good for the money
