Default Pola Trolley Bus Question

Looking to fiddle with another project altogether, and was curious about
the Pola Trolley Bus contraption, in or about 1/87 scale. One I saw at
a model rail show some decades ago seemed pretty sturdy and
well designed, for what it was. Verrrry hard to find in USA.
My questions, did they hold up well over time? Any links to
this item (I've searched and found but little)? What about
vintage Faller (not terribly keen on their trackless system,
just because it's not vintage)?

I have a Faller car system bus. I have hardly ever used it from new. It needs new batteries as they dont store well in a slightly damp enviroment.
The downside is it has one speed. It is either on or off. I also bought the proper road to go with it which was very expensive. Is much cheaper to use the guidewire!
My bus was the first one out in H0 scale.

Hi Chops & MG.
I can't find any reference to Pola trolley busses but these were common a few years ago and were sold under different names.
They were made by Eheim and later Brawa and can be found sometimes for sale.
These are a pair belonging to me .
If these are the ones I can provide further info.

Those are the ones. And yes, what is the proper road material? I never
see roads listed for sale. As for the full on, full off nature of the thing,
does it travel moderately or too fast? Batteries? Does it run on a small
watch battery sort of thing or does it achieve power by the caternary?

Kindly post more, if you can. Thanks!

Roads... The Faller car system had slot together plastic road in the range of products, the idea being that one can bring out the system for fun and pack it away again much like a trainset, but for road vehicles. The Faller car system has rechargeable watch batteries in the vehicles where after they are used one charges them up again for the next use. Faller do a whole range of spare parts from batteries to wheels with their tyres. The Faller system has steering with a magnet on it so the vehicles follow a magnetic wire. They move at a sedate pace. For city traffic it would be too fast. For a larger road (Eg. Dual carriageway or motorway) it would be a bit too slow. One could either get some wire that magnets stick to and lay it along ones road on ones layout, and then cover with a top road surface, or one could buy the ready made roads like I have. They are a little too flat and the joins are visible, but they work well.

I dont know about the trolley busses as I've never had one. I did have a monorail system once which was designed to ride above the train height. That was something different!

Hi. The Eheim/Brawa busses are like an upside-down model railway/railroad in that they are powered and steered by the overhead conductors so need no special road surface.
The motors are cleverly designed with an AC motor with a single winding so that they will only run forwards when powered by an AC controller ( Marklin) or a DC normal train controller. This is because the busses cannot reverse because of the steering and also can be used with AC and DC controllers so they only need to make one version ! They are fully controllable like a train.
The later Brawa busses have DC motors with diodes so that they also only run forwards but will still run on AC or DC.
They were produced from about 1950 until 2001 and my older busses are in perfect working order even down to the lamps working so they are fairly robust.
There was a range of accessories which are shown on this site which also gives more info.

Here are my other two busses.



If you search for "Eheim" on the U.S. well known auction site they often appear - there is one on there now !
Hope this helps. Colin.

They are very impressive. Actually the idea is ideal to copy for 7 mm scale use as well as an interesting scratchbuilding project, though I must admit, I have enough little projects to follow.

Thank you very much, I was not able to effectively identify this
information, although I tried.
