Trains around Copenhagen

Here are metro trains, suburban trains, regional trains, intercity trains, and a freight train around Copenhagen, Denmark.
The Copenhagen Metro is driverless, so passengers have a great view out the front and rear of these trains, as you'll see in the video.
Copenhagen's S-tog is an urban-suburban rail service similar to the S-Bahn networks that are found in many German cities. It provides frequent service throughout the Copenhagen region.
While not exactly a regional train since it operates a short route, the Nærumbanen is an interesting little railway that can easily be reached via the S-tog. The Nærumbanen uses small diesel-multiple units that kind of look like buses.
On the mainline the intercity and regional trains use electric-multiple units, diesel-multiple units, and electric locomotives. A Hector Rail freight train also makes an appearance in this video.
