The minutes drip by, and still no sign of any public transportation. I’m running late. Perched on the edge of a curb, squinting down the length of Market Street in the US city of San Francisco, I find myself twitchily tapping my phone, only to wince as the time ticks away.
But suddenly the traffic parts. A faint bell rings on the horizon. And up the Market Street rail line rumbles my deliverance: a 1928 wood-panelled tram in green-and-white trim.
