Route Planning and Network Layout
The ICE system is a polycentric network. Connections are offered in either 30-minute, hourly or bi-hourly intervals. Furthermore, additional services run during peak times, and some services call at lesser stations during off-peak times.
Unlike the French TGV or the Japanese Shinkansen systems, the vehicles, tracks and operations were not designed as an integrated whole; rather, the ICE system has been integrated into Germany's pre-existing system of railway lines instead. One of the effects of this is that the ICE 3 trains can reach a speed of 300 km/h (186 mph) only on some stretches of line and cannot currently reach their maximum allowed speed of 330 km/h on German railway lines (though a speed of 320 km/h is reached by ICE 3 in France).
The line most heavily utilised by ICE trains is the Riedbahn between Frankfurt and Mannheim due to the bundling of many ICE lines in that region. When considering all traffic (freight, local and long distance passenger), the busiest line carrying ICE traffic is the Munich–Augsburg line, carrying about 300 trains per day.

Famous quotes containing the words route, planning and/or network:
“no arranged terror: no forcing of image, plan,
or thought:
no propaganda, no humbling of reality to precept:
terror pervades but is not arranged, all possibilities
of escape open: no route shut,”
—Archie Randolph Ammons (b. 1926)
“Most literature on the culture of adolescence focuses on peer pressure as a negative force. Warnings about the “wrong crowd” read like tornado alerts in parent manuals. . . . It is a relative term that means different things in different places. In Fort Wayne, for example, the wrong crowd meant hanging out with liberal Democrats. In Connecticut, it meant kids who weren’t planning to get a Ph.D. from Yale.”
—Mary Kay Blakely (20th century)
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
