Railway construction sites are hazardous working environments. Especially when there live traffic passing by and work must be halted carefully for every train.
Traditionally, a handheld horn is used to warn the team of workers on site of an oncoming train. Our customer tasked us to create a digital alerting system that can be worn by the worker all day, no matter where. The device receives alerts from a handheld unit or a remote system and then warns the wearer with a flashing light or a loud tone, depending on the severity of the alert.
Our customer was able to successfully demonstrate the prototype in front of a Swiss railway company.
