People who habitually sleep through their train stations could soon be woken

The device is preprogrammed with the name of the station where the owner
wants to get off. A beacon by the track a few kilometres ahead of each station
transmits an identifying code. The device compares the codes with the
preprogrammed station and bleeps to wake the traveller.
