RailWay Routing instead of Car

[sadaqatbukhari]

I need to route on railways line using graphhopper instead of car. Could you please guide me how to do that using api? I need to provide following options http://wiki.openstreetmap.org/wiki/Key:railway.

Public Transport is currently not supported.

Public transport is not only a different beast algorithm wise it is also a data coverage problem and therefor we won't support this in the near future. For graphhopper itself and just routing on the railway network without the time information @jansoe already replied here on how to do that: graphhopper/graphhopper#443
