    The Pantograph Barrier: Part 1 of 4 Of Pantographs & Wires

    The marriage of the pantograph and the catenary has been wonderfully stable and productive for 120 years, but the insurgence of high speed trains has started to reveal a “Pantograph Barrier”.

Part one will begin with the history of overhead electrification technology and where the technology is today.
