New Trains – By Gdicm:
I’m home from Inverness, but I’m going to have to finish this post later. I’m shattered. (If you read my Facebook Lead earlier)
Firstly: How to waste money and time showing off the Bugatti way. I’d put them in prison for that.
We used to say that if you put a big engine, i.e. a lorry one, in a small car with a suitable transmission you could go any speed. If you had enough road. Less than two minutes to cover a five mile straight on a race track is pointless, not clever. (250 mph Bugatti) Not if you have a good model maker and a proper wind tunnel. It is not proper engineering. It is playing at it.
Anyway: How to construct buses and lorries that run on rails and roads. Part 1.
Firstly: The rails must be raised to allow the road wheels clear of the track. Can’t be done as they won’t clear the small bridges? Wrong.
Rails can be raised by lowering the sleepers. except over metal bridges, but as they have plenty of clearance the rails can be raised at that point. We’re not after speed.
The rolling stock would be specially built, but no great problem there. With the rail wheels between the road wheels and higher. Enough to keep them clear on the roads. Small rail wheels, and you’d never see them. Transfer boxes for separate drive/s, and automatic gearboxes.
I was studying the carriages in Inverness station. The ones Britain can’t build any more. No wonder. They’re four times longer than they need to be, and an engineering catastrophe. I’d not touch the contraptions for love nor money.
Meanwhile: I’m going to have to go to bed for a while. In the meantime I’ll let you work out how to deal with level crossings.
