A loaded westbound grain train derailed just west of Landis around 8:15 a.m. Wednesday, CN says.

Forty-one hopper cars derailed, spokesman Patrick Waldron said in an email.

There are no injuries and no dangerous goods are involved.

CN crews are on site with heavy equipment and will be working throughout the night, and likely through Thursday morning, to clear and repair the rail line.

The corridor west of Saskatoon remains closed to through traffic.

The investigation into the cause is ongoing.
