What the article doesn’t mention is that the train driver/engineer was worried that the terrain under the tracks was weakened by the weather and rain. The driver got in touch with the command centre and they agreed to the suggestion of lowering the train’s speed, which meant that the derailment wasn’t as dangerous or critical as it could have been otherwise.

Also, the brook Susabäck (bäck = brook) is not a river. It is a brook. “The rustling brook river” sounds like “DVD disc”.
