An alternative overhead system: the Rigid Overhead Conductor-rail System (ROCS)

摘要

THE COSTS of the recent UK mainline electrification projects have attracted much adverse publicity, resulting in delays to projects and the cancellation of future electrification projects. A look at the way electrification infrastructure projects spent their budgets shows that a major chunk of overall cost was associated with achieving 25kV electrification on the existing Victorian infrastructure. A lot of stations, bridges and tunnels cannot achieve compliant electrical clearances required for a 25kV electrification system as they were never designed to accommodate electrified stock in the first place.
