Non-intrusive crossover system

Vastly overscale flanges will make it more of a challenge in model form.

I've seen a similar system in use on streetcar tracks in San Francisco.

Not quite sure how they can apply for a patent for this because the Penrhyn Quarry used something like that.

There was a very similar system used in some sort of yard in New York, used to gain access to the engine shed if I remember right. Sadly I lost the link during a computer melt-down, but the site was something to do with US signalling.

Known, I believe, as climbing crossovers, these have been in use on industrial light railways for many, many years.

Obviously the principle itself is well known, but if they have a developed, say, novel deployment or fixing methods then it may be patentable.
