New Trains – By Gdicm Part 3.:
I was thinking today about the vision by the river of Cherbar in the Bible. How the wheels lifted up and ‘turned not as they went’.
This was consistent with what I wrote in Parts 1. and 2., except it means that the wheels on the track must be on a separate drive, or even axle, from the road wheels. In order that they don’t turn while on the rails. Pity that, because it would of simplified the transmission greatly. Any way round this?
Trust a Prophet to complicate things. To be honest I knew the wheels ‘would’ turn with the drive if the disc brakes were doubled as drive wheels, and was thinking about that when the Bible text sprang to mind. (That vision has nothing to do with this I should think)
Anyway However: I saw a virtual reality computer programme on the net where they can fly virtual planes through virtual hoops and race them.
That being the case they could build a virtual railway to conform to the minimum requirements to travel on railways. Small bridges exist, and it would cost too much to renew them. Therefore a carriage has to be built to fit. Once the axles were designed and built, they could be tested on a real modified track. With every known obstacle a railway faces included in shutter board joinery. Bridges, crossings, points, on and off access points. etc. On and off is easy. With raised rail it’s just a case of driving on and off with tapered in and rising ends of track. The rails would automatically catch the rail wheels driving on, and leave them when driving off.
Only when the axles and hydraulics with transfer boxes are perfected by design can the chassis be built. Up to then it’s a case of temporary beams to adjust it ‘Just So’ and attach the hydraulics and axles and suspensions to bearing in mind the need for carrying people in the passenger frame.
Then and only then could the main frame be included. To fit under the bridges etc. All seems very complicated, but in fact it’s not really, providing each stage is completed within reason before moving to the next.
Better built with a real, purpose-built, track. Or adapt a small section of the Aviemore to Boat o’ Garten steam enthusiasts line. Or the Keith – Dufftown line. A bit like the early demonstrations of steam, where they built a track for the purpose. Except you’re using it to solve the many problems properly and in the simplest manner. Lay out a section of old railway line complete with every obstacle British rail can come up with constructed of wood, and remember they will not be on the side of this. At first. So expect to be told of every obstacle there can be, and some more besides. Those Steam enthusiast lines are everywhere in Britain, and you just need a wee bit.
