Now the tunnels have to be remade for additional funds.
The government of the Australian state of New South Wales has ordered new passenger trains from South Korea for two billion dollars. Korean transport is equipped with stations for charging smartphones and bicycle racks. But there was a problem: the cars are too wide for existing tunnels. Officials decided not to cancel the order, but to change the tunnels and slightly weaken the safety standards.
The old trains were 2.9 meters wide, and the new ones – 3.1 meters. Because of this, the distance between wagons and tunnel walls, prescribed in the standards, exceeded the minimum. According to local media, in some tunnels the train runs the risk of crashing into something.
