Actually I use this strategy:
Rail:
Freight:
CargoRail (1,2,3,4,5…) (goods)
Passenger:
(city name) – (city name)
Road:
Bus:
Schnellbus (1,2,3,4,5…) for long distance bus
(name of the city) (1,2,3,4,5…) for local bus
Tram:
(name of the city) (1,2,3,4,5…) for local trams
Interurban (1,2,3,4,5…) for intercity trams.
