Granitbahn

This was a good watch.Absolutely fantastic, what a great video and brilliant railway with a terrific backdrop , the conditions make it looks like the real thing , thanks for posting![]()
I would not wish to forestallThis was a good watch.
However, while watching, a question came into my head. Is this running on track power or battery?
If it is track power, does the snow over the track not conduct electricity and cause a short circuit - the same way bridging the rails with a piece of metal would? For that matter, if the track were covered with water, would not that also short it out? Or do snow and/or water not conduct electricity?
I mean if you were unlucky enough to drop a powered up hair drier into your bath, the results could be catastrophic, so why not water or snow completely over the track? I guess I could be missing something here? Just curious.
[its not the sort of thing I would like to test out on my track! I have had bad experiences with bits of stray metal - once in an LGB level crossing - which had a metal rod running under the track at right angles - until I twigged what was going on and removed it!! - the metal rod, that is. Indeed, I think I may have removed the whole crossing - it was many years ago and I remember the problem, but not the solution. I used to have several of these crossings - the ones that are closed by the weight of the approaching loco. I only have two now, and I suspect the rods have been removed. The things don't automatically open and close anymore, but they make nice track furniture!]
My understanding that clean water does not conduct electricity well, in fact in the modelling challenge series, one layout ran track through water.This was a good watch.

Good question and thanks for watching. I’m running on 12A 18V track power. The Massoth central station is very good at dealing with short circuits and when they happen (typically derailments at points) the system shuts down and I’ve never experienced any damage. Snow and ice cover has never interfered with operation, primarily because both are poor conductors of electricity due to the presence of air in snow and the lack of mobile ions in both. If you were to add salt to try and melt any ice cover, this would increase the number of mobile ions and then you might create a problem.This was a good watch.

Wonderful video!! Love the way your railway crosses the creek/brook several times1 A+++++In sub-zero temperatures and Alpine conditions following a heavy snowfall on Monday 6th March 2023, a Bernina railcar completes a full circuit of the Granitbahn. Much thawing out required following this expedition
