(KRON) -- Those of us who commute through BART know that the transit agency's social media page posts more unexpected delays than a busy airport on the Fourth of July. On Tuesday, BART officials claimed a recent change helped reduce the frequency of its delayed trains. Could 24 hour ‘pit stops’ make SF streets cleaner? Homeless advocates say yes It wasn't exactly greasing up the tracks or increasing staff that led to the decrease, but rather, BART claims the improvement stems from police enforcement. In the past six months, the BART Police Department reported more than 10,000 "enforcement contacts," nearly double the 5,490 figure in 2023. BART PD claims that as enforcement contacts have increased, the number of trains impacted by "unwanted activity" has decreased. According to BART, the number of BPD incidents causing delays has dropped from a high of 374 in May 2023 to 255 in August this year (see chart below).

"The last four consecutive quarters have been the first in BART’s history where the percentage of riders who reported seeing BART PD on their trips exceeded the department’s official goal of 12%," BART said. In the most recent quarter, nearly 20% of riders reported seeing BART PD’s safety presence. The increase in activity comes as BART continues to implement its Safe and Clean Plan.
