Two pantographs of ES 64 U2-101 of <a href="http://www.hupac.de/">Hupac</a>
seen at Aachen West on 19 July 2002. The one in the foreground has a narrow
wiper for the swiss catenary and 25 kv AC systems, the other one has a wider
wiper for the german and austrian catenary. The narrow pantograph is very
clean, it seems it was not used often by now.
