Operation
The 190 km long system has 75 stations and serves approximately 330,000 passengers every workday. The trains operate on the standard gauge tracks of the Deutsche Bahn AG (DBAG) and are powered by single phase AC at 15 kV and 16.67 hertz, taken from overhead wires.
Installation of new passenger information systems began in December 2004. These systems indicate the actual real-time status for the next three trains rather than just the scheduled departure time and route of the next train.
All seven S-Bahn lines travel under the downtown area to Schwabstraße, and three continue on to Vaihingen through a dual-track tunnel. This tunnel, however, presents a bottleneck that limits train headways to two and a half minutes, meaning that trains on each individual line can only run at 15 minute headways.

Famous quotes containing the word operation:
“You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
—Thomas Henry Huxley (1825–95)
“Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.”
—Francis Bacon (1560–1626)
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
