180+ MPH Technology Option
At speeds of 180+ mph, electric traction provides the only real alternative. The French-designed
TGV-Atlantique is one of the most successful examples. The advantage of this type of
equipment is that train size is relatively flexible, with the ability to add or remove cars. The
disadvantage is the increased capital and maintenance cost requirements for the overhead
catenary system. It has also not yet been introduced into domestic operation in the US, which
may result in modifications to European design train systems and components. It is also a
technology that has not been fully approved for domestic service by the US DOT/FRA.
