LINT is the name of the Alstom Coradia LINT regional train type that has operated on local lines in the Netherlands, and vertreksignaal is Dutch for departure signal. The tone belongs to the regular departure procedure at the station, rather than to a film or game. Rail fans and transport enthusiasts share recordings like this online to preserve the everyday sounds of specific train types, and editors reuse the signal because it is closely tied to Dutch regional rail travel.
