European train and tram show, has bow collector trams for Huw--

But watch for the bicycle in the beginning!

Any ideas how it was done? (assuming it's not a photoshop job)

Just a wild guess on my part.

Under the roadway there could be a small loco with a magnet on top.

The bike is metal and is dragged along by the magnet.

The roadway would need to be thin. allowing the magnetic field to do its job.

You would have noticed the riders legs are blurred, so I would guess they were not functional.

OK I shall crawl back into my hole  and shut-up.

I would have thought the same thing , Don, if it were an auto or truck.

But what keeps it upright?

And get out of that hole-- there are a family of wombats that have a lease on it.

AH HA!

That explains it Steve, Thanks--and thank your brother!

When you slow it down ,do the riders legs work with the pedals?

If so, the pedals must be driven from the rear wheel by------What ? L:

Pretty darn clever, I'd say.

I agree.

This layout was at the Warley show (last weekend at the NEC, just outside Birmingham) - and came personally recommended to me by a trader at the show, whom I've known as a friend for the past 20 years.

Unfortunately, when I passed the layout, the cyclist wasn't doing his circuits, so I didn't get chance to study it close-up.

Looking at the footage though, it looks like the legs are hinged (at the hips and knees) and the feet fitted to a clear wheel, that runs along the road slightly to one side of the road wheels. This would explain how the feet move and the bike stays upright.

As for the "foot" next to the rear wheel, I'd guess that it's probably a small magnet - with another one on a rope loop under the layout, used to pull the bike along.

I'm probably wrong with my guess - but, if anyone on this site knows any of the people who built this layout, I'd be very interested in finding out what was actually done.

herb, i remember a website, cant think of how i got there, because i push buttons to "see where this goes".  anyway, there was an ho layout thet had vehicles travelling along a road.  i believe this was done with some sort of magnet switching polarity.  does tha sound possible?  thats what i remember, now if i can think of where i found it...........

There is a commercial system which works in a similar way to this - the Faller Car System. It's based on vehicles, with magnets fitted to their steering axles, following a steel wire buried in the road. Here are a few links - to sections of a site which describe the system, how it works and adapting the chassis to fit into alternative bodyshells:

http://www.midlandred.info/faller.shtml

http://www.midlandred.info/fcs.shtml

http://www.midlandred.info/fa161513.shtml

http://www.midlandred.info/efefaller.shtml

http://www.midlandred.info/fallercircuit.shtml

This site also includes sections on route setting and loads of other goodies.

 
Some of the model railway exhibitions I've been to have included model bus layouts - usually exhibited by members of the Model Bus Federation. A few years back, one of their magazines included full instructions on how to build a DIY model chassis (which used the space inside to allow the parts to sit low in the model - and also used larger batteries to increase the range). Not being a MBF member (and not really being too interested in model buses), I don't have a copy of this.

 
As for layouts using this system, I wouldn't be surprised if these were to include the German Miniatur Wunderland - I can't be 100% certain, but I get the impression that it includes a good cross section of the techie stuff on the market.

Other than this, I'm afraid I can't be of much help.
