6061B T6 Railway Rigid Catenary for Metro Subway and High Speed Train

Installation of rigid overhead catenary in Crossrail ...

Jul 09, 2018 · The Rigid Overhead Catenary System is an overhead line feeding system for railways infrastructures which can be considered as an alternative solution to the standard flexible catenary and 3 rd rail feeding systems that make it predominantly suitable for use in underground train infrastructures. The main advantages offered by this system are:

Sep 15, 2016 · To solve this problem and increase the maximum speed of high-speed trains, a high stiffness carbon/epoxy composite was used for a new design of the upper arm of a pantograph. For lightweight design of the upper arm, the composite was applied to the inner surface of a 3 mm-thick aluminum pipe (6061-T6) with a stacking sequence of [±5] 5 T .

Building rail cars from aluminum is a tested and proven way to increase railroad efficiency. An excellent example is the third generation of the TGV Duplex, a French high speed train, converted from steel to aluminum to achieve a 20 percent weight savings, while also converting to two decks and keeping the axle load below 17 tons.
