A computer error stops trains in Germany
110
On Tuesday night, all trains stood still. They stopped for 2 hours. A fault in the radio system caused this. The company changed a device. The software had an error.
Normally the system reports errors alone. Then it switches to a second system. This time the system stayed silent. Workers had to find the error. They checked for a cyber attack. Then they switched the system by hand.
The radio system is called GSM-R. It is over 20 years old. The company wants to improve it. They do repairs deep in the night. They install no new parts now. A new system comes in 10 years.
