from a german point of view, we have two laws, the EBO (for railways)
and the BOSTRAB (for trams). In short: BOSTRAB allows street
running, EBO allows bigger trains. If you go into details, there are
several sub-laws for different types of trains, considering loading
gauge, vehicle lenght and weight, maximum speeds, if and how you have to
put up signals, different regulations if you want public funding etc... German
bureaucracy at its best.
I have no idea under what law the
london underground would run, e.g. there are S-Bahn tunnels for suburban
trains in Berlin, Hamburg, Munich, Frankfurt, Stuttgart that run under
EBO. On the other hand, the 4 full subway systems (U-Bahn) in
Hamburg, Berlin, Munich, Nürnberg run as a sub-law of BOSTRAB, I don't
know why. As they're full seperate, there is no lenght restriction.. Pre-metro
Stadtbahn systems, e.g. in the Ruhr area, e.g. Essen (to continue our
ABC), which have parts underground, parts street running are BOSTRAB as
well. If a line is partly street running, lenght restrictions (75
meters) do apply, if it's fully seperate, longer trains would be
possible. |
