Green ticket is a single with one transfer.
Zone 1 is the city area, all tram routes are in zone 1. (Helsinki had four zones and two sectors, tickets were for 6 zones.)
Price is cheap 40 markka and in next year we took penni again in use (not used in 1949-1962) and the tram price was then 40 p.
I think State Railway tickets are for luggage storage or for public toilet in station.
