The route starts at Praha-Bubny Vltavská, not far from the Vltavská metro stop, and eventually goes as far as Hostivice and Rudná u Prahy and then to Praha-Smíchov (Smíchovské nádraží). The train then does the route in reverse, hitting all the same stops a second time. People can get on and off anywhere along the route, but tickets purchased in advance are required.
