Unity RCMP are reporting a train derailment which happened south of Rockhaven on Saturday.
This is the second incident in this area in less than 2 weeks.
Rockhaven is in the R.M. of Cutknife, west of North Battleford.
Police say 4 railcars went off the track on Saturday, leaking asphalt.
An excavator was brought in to create a berm to prevent further contamination.
No roads were blocked by the derailment and no waterways were affected by the spillage.
The first incident was on July 17th, where 7 Canadian Pacific cars carrying liquid asphalt derailed.
They remained upright and nothing was spilled.
