There is one particular hazard associated with trams powered from a trolley off an overhead line. Since the tram relies on contact with the rails for the current return path, a problem arises if the tram is derailed or (more usually) if it halts on a section of track that has been particularly heavily sanded by a previous tram, and the tram loses electrical contact with the rails. In this event, the underframe of the tram, by virtue of a circuit path through ancillary loads (such as saloon lighting), is live at the full supply voltage, typically 600 volts. In British terminology such a tram was said to be ‘grounded’—not to be confused with the US English use of the term, which means the exact opposite. Any person stepping off the tram completed the earth return circuit and could receive a nasty electric shock. In such an event the driver was required to jump off the tram (avoiding simultaneous contact with the tram and the ground) and pull down the trolley before allowing passengers off the tram. Unless derailed, the tram could usually be recovered by running water down the running rails from a point higher than the tram. The water providing a conducting bridge between the tram and the rails.
In the 2000s, two companies introduced catenary-free designs. Alstom's Citadis line uses a third rail, and Bombardier's PRIMOVE LRV is charged by contactless induction plates embedded in the trackway.
