I got my 1st fancy phone Jan 23rd & this morning it was dead! Trip 75miles to the city to exchange it - IPhone5s. I don't have internet without it...
I think you're onto something there Stevie
... though it wasn't a high spot in the track, I purposely spun the tracks @0:45 to get rid of any stones or lumps so the tracks were flat footed & it wouldn't teeter. It was @1:25 when I turned to the left a bit - raising the right track an inch or so up the slope that caused it to slide a bit during the swing... had I turned right it may not have move. Although it's still fluke it didn't tip right over.
