Pantographs, well, for those who don't know what it is, it's the mechanism (with arms and linkages and etc.) on top of an electric train, that collects electricity from the overhead cantenary for the train's propulsion. Maybe I can say it's a fancy version of the trolley pole for trolley busses and old school streetcars. Below is a picture showing the parts of a modern Z-shaped single-arm pantograph from the German Wikipedia page of pantographs (there are many types out there, I won't go into history and all that now but they are linked here). Unfortunately I have not a clue what it's saying... je ne comprends pas Allemand and oh wait that wasn't even German.
