Add rail lines in OpenRailMaps

Hello, I was looking for a railline or railway maps. Then I found out OpenRailWayMaps and it is awesome. But as a matter of great sorrow, I found my the railway map of my country is incomplete. All the rail tracks are not added.

How can I add new rail lines ?

Thanks !!!

Openrailwaymap uses OpenStreetMap data - read to get started adding things to that.
