At 42 years old, BART is showing its age, with increasing numbers of breakdowns, delays, and service interruptions. This survey from last month told us as much, but now the Chron just analyzed a bunch of BART stats to figure out where the transit agency's biggest pain points are. Let's take a look at the numbers!

  • 1972: The year BART started running
  • 350,000: The average number of BART rides taken per weekday in 2012
  • 420,000: The average number of BART rides taken per weekday now
  • 441,428: The average number of BART rides taken per weekday in October (typically, BART's busiest month), 2014
  • 26%: The increase in BART delays lasting 15 minutes since 2012
  • 96%: The percent of BART’s trains that ran on time as of 2012
  • 87%: The percent of BART's trains running on time as of their last quarterly report (their lowest rate "in nearly a decade.")
  • 40: The age of "many" of BART's cars
  • 25% The percent of delays in 2014 caused by problems with railcars (for example, issues with doors, brakes and train control)
  • 669: The number of railcars in BART's fleet
  • 775: The number of new cars expected to arrive to replace the aging ones starting in 2016
  • 18%: The percent of delays caused by trackside equipment, most "caused by false occupancies, a glitch in the computerized train control system that shows a train is occupying a section of track when nothing is there, and routing errors."
  • $4.8 billion: The amount of money BART needs, but does not have, to get a modern train maintenance shop and a new computerized train control system.
  • 18%: The percent, in 2014, of BART delays caused by police activity
  • 6%: The percent of delays caused by medical emergencies, "which cause trains to stop, often until paramedics arrive and remove ill or injured passengers" in 2014
  • $10-$12 billion: The amount of money it would cost to build an additional Transbay Tube
  • 74%: BART's current customer satisfaction rating, its "lowest level since 1998."
