Delegates to the Saskatchewan Urban Municipalities Association convention are to debate a resolution calling on the group to lobby the federal government to improve rail safety standards.
Association president and Weyburn Mayor Deb Button says there's concern because trains are moving faster through communities than the set speed limits.
Button wants to see speed limits enforced and by someone other than rail companies themselves.
The resolution brought by the village of Clavet (KLA'-vet)says speeds exceeding 100 kilometres an hour have been experienced in some urban centres.
It says many cities, villages and towns have houses near a railway and many lives would be endangered if a derailment occurred.
