Question: 1 / 400

How are BART's trains powered?

By diesel engines

By solar panels

By a 1,000-volt DC third rail system

BART's trains are powered by a 1,000-volt DC third rail system. This method uses electricity supplied through a third rail that runs alongside the tracks. The design allows for efficient transfer of power directly to the trains, enabling them to operate smoothly and effectively. This system is commonly used in many urban transit systems as it can provide reliable high-power electricity required for rapid transit services, ensuring trains can achieve the necessary speed and power needed for both acceleration and operation across the system.

Other options, such as diesel engines and hybrid technology, are not applicable to BART, as the system is entirely electric and does not utilize fossil fuels. Solar panels could contribute to energy generation in other contexts, but they do not directly power the BART trains in this manner.
