Current switching in Padborg
In 2005 I managed to capture the same thing in Padborg Denmark, just after crossing from Germany. Our train was having the locomotive switched out to a DSB one and we had a few minutes to let a passing freight go by. Padborg is the location where the German 15KVAC 16 2/3Hz supply changes to the Danish 25KVAC 50Hz. Matter fact, right in front of the station is where the changeover occurs. I managed to get the shot of the freights pantograph lowering, but didn't see it through the viewfinder...and missed it coming back up just as it passed me as I was panning the head end of the locomotive.
Enjoy!
