Point (Turnout) Control

[playmofire]

I had a work colleague, who was studying Quantum Physics, correct me when I said 'the shortest distance between points is a straight line'.
He said that in quantum physics points do not exist so therefore straights lines don't either, he started explaining this but when I glazed over he just gave up.
That would explain most of my cuts.

Ah, the ancient Greek Zeno had that problem in considering the flight of an arrow. If, he argued, at any instant in time an arrow is at a particular point and so is stationery, so how can it move from through the air one point to another.

I did read that article on ge_rik blog this morning and found it interesting, certainly "food for thought".

BTW - here's a link to my blog post on making the V2 of the point levers

Instead of push pull, you could use torsion control. A lot simpler than push pull as you don't need bell cranks. However, the limitation is the distance over which it remains operational.

Ah he clearly never understood the concept of velocity.
