Still ding-dinging after 110 years
Trams celebrate anniversary with memories of Margaret Thatcher, fleas and the Sars epidemic

"Ding ding" - it's a sound that is part of the lives of many Hongkongers, but for Yip Won-cheong and Ko Lai-bing, it resonates much deeper.
Yip, 65, has worked for Hong Kong Tramways for 40 years, and is now its longest-serving employee.
Ko, 59, has been a tram driver for 25 years. Late British prime minister Margaret Thatcher and former governor Chris Patten have been among her passengers.
As the company celebrated its 110th anniversary yesterday, the pair relived some of their memories, including the early days when fleas used to bite the drivers.
Yip's parents and brother also worked on the trams. Yip had been a construction worker and shopkeeper before signing up to Tramways.
"But my joining had nothing to do with my family [working there]," said Yip. "I met an uncle one day on a tram, and he introduced me to the company. My father didn't know I had joined the same company before I started work."
Yip started as a driver, but became an inspector after seven years. He has also trained drivers and is now a senior inspector.
