2 Hong Kong Subway Trains Collide

Hong Kong tested a new subway signal system before commuter trains began early Monday. It did not go well. Two subway trains collided between the city's Central and Admiralty stations and both drivers were hospitalized, the BBC reports. There were no passengers on either train. The Mass Transit Railway operator said millions of commuters could face disruption and repairs are likely to take "a long time." The SelTrac signaling system developed by French company Thales, which is supposed to allow the system to run trains more frequently, was also blamed for a train collision in Singapore that injured 38 people in 2017, reports the South China Morning Post.
