Commuter train

It is usually optimized for maximum passenger volume, sacrificing comfort and luggage[?] space. The range of commuter trains is quite large, due to the high speed at which they travel.

Commuter trains differ from undergrounds mainly by being larger and running above ground; they run on standard gauge track, while for an underground system this may not be the case. Commonly used on the standard railway system, commuter trains also travel faster and have a longer distance between stops than underground trains. Because of this, commuter trains are used for longer distance travel than undergrounds.

In Germany, a commuter train is known as an S-Zug.
