Certain sections of the BART system are designed for 80 mph operations, however the maximum operating speed BART currently uses today is 70 mph. It is unlikely that 80 mph operating speeds will be used again due to the increase in motor wear and propulsion failures at the higher rate. There are also higher impacts on track maintenance. In addition, the 80 mph segments tend to be short, and the higher speed benefits are limited as train speeds become inconsistent.
BART explains it has total of 662 trains, but about 535 are in service during peak commute times, about 86.5 percent of its fleet. BART said it runs more of its fleet than any other major transit agency despite having the oldest trains in the nation.
