BOStrab (German tram operating rules) compared to Australia
  Robbie Smith

The German light railway and tram operating regulations are legally defined
by (presumably) an act of the Bundestag, and they go into absolutely
everything from vehicle technical requirements to signalling to worker
qualifications. The EBO (railway operating rules) even prescribes a loading
gauge.

Given this is Germany, I'm not surprised how thorough they are. It's due to
the BOStrab/EBO that the Combinos in Melbourne have the three headlights ∴
, as that is legally defined there to indicate the front of a train
movement.

Australia has nothing even remotely like this, do we? Everything is defined
by the State Governments or the individual railway operators, or in the
case of NSW, by the company who tenders the trams.
