If you can't test the rail material for composition, atleast test with magnet.
Mostly, rails are made of Hadfield manganese steels which are non-magnetic.
If so, weld with AWS E 307 - 16 without any pre-heat on the rail part.
This is the best recommended solution for joining Hadfield steel to Carbon steel.

you should give the standard type written on the rail parts and search about that type material to know the electrode required.

I face a problem in my site … I have a rail do not know its material … we need to weld this rail to CS base plate (fillet weld) .. I told them to use E9018-D1 but it was not available they use 7018-1 but joints is cracked … please confirm me the electrode to use
** the rail is from Turkish railways rails
