The Amsterdam City Center Line is a small hopper bus service which runs in a circular route around the city centre. It is run by a private company City Shuttle Services (CSS) and started operating in October 2011. |
The City Center Line effectively replaces the old "Stop/Go" €1 service which had been operated by city transport company GVB - but was pulled at the end of 2010.
The circular route is similar to the Stop/Go. Starting at Oosterdok at the OBA library it heads west via central station, then turns south and runs along the Prinsengracht canal. At Leidsegracht it makes a quick detour up to Herengracht before rejoining Prinsengracht and continuing all the way to the river Amstel. Here it turns north and stops at Waterlooplein and then Nieuwmarkt before returning to Oosterdok. A useful route map can found here.
Here is the bus on its inaugural day of service:

Tickets for the bus cost €2 one-way or €6 for a day ticket. Passengers can hop-on and hop-off at any point along the route.
The City Center Line bus is quite a useful service, connecting many places of interest around Amsterdam centre that are not accessible by tram. Hopefully the operator can make a success of the service.
