text: There are 2 POIs for the bus stop "Σερρών" (while only 1 physical bus stop at this position): Nodes 1212930391 and 2786690198 with slightly different info. Not sure if consolidating is a good idea, as will have to choose between public_transport=platform (better) and public_transport=bus_stop (old). However, the wiki page for "platform" proposes that the "bus_stop" tags should be kept in order to ensure compatibility with legacy software, at the price of redundancy.
