Map details out of date
Mernda Station at -37.601780, 145.101227 is shown as Proposed in Locus Map but has been constructed and operating for nearly 10 months. I understand you source your maps from Open Street Map. However, OSM is up to date and clearly shows Mernda Station and the railway tracks. There are two more operating stations south of Mernda, Hawkstowe and Middle Gorge.
