How can a train run under -50°C?
Below -50°C, starting the train is the most complicated task.
Below -50°C, getting the train started – i.e. getting the electronics to work – is the most complicated task!
To achieve this, the equipment is preheated, either via an electrical socket or via the pantograph, to raise its temperature from -40°C to -25°C, while pre-empting possible short-circuits caused by condensation (via special varnishes on the circuit boards) and creating de-icing tunnels for the bogies. To get the machinery – and therefore the train – to work, the obstacle deflectors are turned into snowploughs and specially adapted materials, such as special steels, are used.
