BART Riders Get the Equivalent of 224 Miles Per Gallon

A typical car gets about 21 miles per gallon.  A BART rider gets the equivalent of 224 miles per gallon and 422 miles per gallon during the peak commute period.  On average, BART is 10 times more efficient than a typical car driven alone (on a passenger-miles per gallon basis of comparison).  During the peak commute period BART is 20 times more efficient.

BART's Energy Regeneration

BART trains are 100% electric. As the trains brake, BART trains convert their kinetic energy of motion into electrical energy. Some of the energy regenerated during the process is returned to the power distribution system where it is then used by other trains.

An Even More Energy Efficient Future

BART’s new trains will be electric and will offer a variety of sustainable features that reduce energy use and pollution:

  • Lightweight aluminum exterior reduces energy use and the new trainaluminum can be recycled when the trains cars are eventually retired.
  • White roofs reflect heat and reduce the load on the interior cooling system.
  • LED lighting reduces energy use.
  • Seats are 74% recyclable by weight.
  • Space is dedicated for bikes.
