Please calm down folks....
First let me say a 'thank you' to all who left input.
In a conclusion on dirt&dust topic one might say:
- 9V may need some cleaning now and then, but shows a great resistance against
dirt.
- 12V conductor rails collect all kind of dirt much easier and have to be
cleaned in almost every case for smooth operation.
Regarded under technical aspect this may a result of the tribological form of
movement:
12V power pick ups slide just over the middle conductor rails and causes wear,
but does not transport dust easiely away.
9V power pick up works via the stainless steel wheels that are pressed
sidewards against the track. The form of movement is both sliding + drilling
at the same time. That is a way to transport dust easier away. And since it is
sidewards less dust will stick there anyway. Most dust simply follows gravity
and is placed on top of the track.
*******
And of course in a train FAQ one should start with:
- 9V system
- then speak of 12V system ('grey era' + mention the 'blue era' none-minifig
style stuff.)
- then 4.5V system (which has been more common as 'blue' than in 'grey')
- and mention monorail as an extra system in the end.
********
Thanks for sharing your points of view. I think this whole thread is a quite
helpful one now.
Have a nice weekend!
Ben
