And then it happened again.
Another day, another 10 minute delay on the BART system due to “equipment problem”. But today there were two such delays; the first at Colma and the second in downtown San Francisco. I suspect it was the same train that managed to get going at Colma but came to a shuddering halt again downtown. Although apparently there was an engineer on-site and they must have worked their magic as we were motoring again soon enough.
