A BNSF train on a railroad spur in northern Lawrence derailed Wednesday morning.

The derailment was reported at 11:37 a.m. near the intersection of Iowa Street and Lakeview Road, near the Westar Lawrence Energy Center.

Several BNSF employees were on scene investigating. One of the train workers said two wheels of the engine and one wheel on a tanker car behind it had both left the track, but both cars remained upright. The employee attributed the derailment to mud that had built up on the track and to rotten rail ties. Multiple railroad cars were attached to the train.

Police were on the scene directing traffic and diverting traffic both on Iowa Street heading north, and on Lakeview Road heading east, but the scene was cleared at 12:52 p.m., a dispatcher said.
