German railway route numbers

German railway route numbers (German:Streckennummern) are used to designate and identify railway routes, or sections of routes, within Germany. In Germany, there are a total of 3 different numbering systems used by the Deutsche Bahn, which meet different requirements.

These systems are:

  1. VzG line numbers (four digit, unambiguous identification of a railway line)
  2. Timetabled route numbers (three digit, Kursbuchstrecke referring to a route of passenger services)
  3. Restricted speed section (La) route numbers (one to three digit)

In addition there are numbers in the railway operators' timetables; these are not covered here.

gollark: Yes, JUSTICE FOR SOHNDAISFSPOUTIN!!!
gollark: Well, if I *am* allowed to post increasingly bad* versions, I might as well just submit my sort of vaguely working ish version?
