    The Pantograph Barrier, Part 4 of 4: The Balanced Force Pantograph Solution

    Part Four will conclude this series and focus on how the Pantograph Barrier can be eliminated and increase train speed beyond 220 MPH. In review, Part Three of this series discussed why having electrified passenger trains that can go beyond 220 MPH is important to our infrastructure and can change the way people travel.

    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”. This four-part series will examine the technical issues that have caused this 120-year-old technology’s inherent limitations and how advances can lead to the operation and initiation of new, truly high speed intercity services. Part one will begin with the history of overhead electrification technology and where the technology is today.
