Most modern DC electrified railway systems use a totally floating earth as their grounding strategy. A well-known problem related with totally floating systems is that the touch potentials can be dangerously high. In order to reduce the voltages on rails, several devices exist. Most of these devices allow a direct connection to earth when a certain voltage threshold is exceeded. In this paper, ...

s light rail transit (LRT) systems mature and expand, outlying passengers are faced with increasingly longer trip times to reach the urban core. Providing service to these customers by conventional means can be disproportionately expensive for the transit carrier in terms of operating and capital expense. Innovative operational practices to expedite train movements, however, are often confounde...
