Not repaired and still causing trouble.

Contact the RR??

Has NOT been repaired. I suspect it's the RR's job to do, but the fix is important! Danger!

Who can contact the railroad to fix it?

Since no one from the local DPW has contacted you in over six months regarding this issue, I wouldn't hold out much hope that you are ever going to get much if any support by way of getting this fixed.

Please contact the RR responsible for repairing its track.

Fixed!😀
