Atmospheric Railway

Now I'm not planning to do this myself, but interested to read about this 1:6 scale atmospheric garden railway, in the sense of atmospheric pressure not railway with a nice atmosphere.

I wouldn't mind having a vineyard to build a railway in, though...

That is an interesting project and a method of propulsion that harks back to the very early days of railways. Brunel didn't have much luck with it.......

So? Who's going to be the first to build one in 16mm? "Honey, I'm borrowing the vacuum cleaner...!"

Interesting enough, though, he has solved the problem that IKB could not sort out, and that was maintaining a seal.

Traffic Pattern? What pattern? Spuds out; grain in, but cattle, sheep and passengers are a lot less predictable.

In Brunels system they didn't have neodyum magnets. The system of the 89 year old man is just a tube with a magnet travelling inside, the train as another magnet. So there is no seal and much easier to keep a vacuüm..

But in 2018 even his system is very slow and old. Lineair electromagnetic motors have the same sort of propulsion (the propulsion is in the track. the vehicle follows by magnetic attraction) and can shoot a train straight up if needed.

The biggest problem of the vacuüm part in the pipe is that the piston also gets attracted by the train, so making a lot of friction inside the tube, which you don't have with lineair motors..

Nevertheless an interesting way of looking at things.. :thumbleft:
