Because articulated trams offer a number of technical and operating advantages over single cars, their popularity is increasing. Power ratings of 10 kW/tonne (tare) are now considered desirable to give 1.3 m/s2 acceleration and a top speed of 80 km/h. Chopper control is more costly and heavier than switched resistances, and it can only be justified when regenerative braking raises the level of energy saved through their use from 7 to around 30 per cent.
