BART: Walk-left, stand-right rule wears out escalators
Almost everybody who rides BART knows it, and those who dont the unsuspecting tourists, the occasional or self-absorbed commuters quickly find out.
When on BART escalators, stand to the right, walk to the left. And woe unto those who get in the way.
Those people generally get yelled at, said Chris McMullen, a 35-year-old marketing director who commutes to San Francisco from Berkeley. Thats how you learn the rules.
Now BART, with anecdotal evidence from China, suggests the practice may not be healthy for the systems escalators.
The message emerged after BARTs newest director, Bevan Dufty of San Francisco, tweeted last week about the possibility of posting signs, or painting footprints or directions telling escalator riders where to stand and where to walk.
BART tweeted back that unevenly distributed weight speeds the deterioration of the mechanical staircases. BART officials said theyve known that all along, but cited a Wall Street Journal story from days earlier that said Chinese subways are questioning the practice of walkers on one side and people who stand on the other. The story said that in one of Chinas systems, 95 percent of the escalators had suffered wear and tear because of the uneven weight distributions.
Some BART riders responded to BARTs explanatory tweets with the anger and snark that have become a hallmark of Twitter discourse, accusing the system of blaming the stand-walk custom for its decades of escalator breakdowns.
@sfbart @bevandufty Like your escalators you are full of crap BART, tweeted Cody Fitzgerald, referring to the transit agencys problems with homeless people using downtown San Francisco escalators for restrooms.
Dufty, a former San Francisco supervisor and homelessness czar, is accustomed to controversy. But he was a bit surprised by the backlash from BART riders.
My Twitter feed has been explosive, he said. Its like I had a fire hose pointed at me: This is a conspiracy, Dont believe it, Its a lie.
Others jumped to the conclusion that BART was preparing to ban walking on escalators.
Not so, said BART spokeswoman Alicia Trost, who added that the idea was never considered anywhere other than on social media.
We are not, in any way, blaming our passengers or asking that they dont walk on escalators, she said.
The leading causes of escalator breakdowns, she said, are not the uneven loads but weather, debris including human waste and vandalism. With a history of mechanical troubles with its escalators, BART is getting ready to replace about 20 of them, a dozen to be paid for with the $3.5 billion bond measure voters approved in November.
