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.
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.
Part One and Part Two of this series discussed the idea of a Pantograph Barrier and why it exists. Part Three will address why the pantograph barrier is significant, and why operating trains above 220 MPH is important.
