Around 12:01 a.m. the train cars derailed during switching operations.
If you drive along Wayside just south of the loop, you will want to take a different route.
Wayside is currently closed in both directions.
Union Pacific says the train car that was blocking the road has been cleared and they are doing some final welding and clean up to prepare to reopen the road.
They say five train cars in total derailed, two of which are tanker cars carrying chemicals.
Union Pacific says the cars carrying chemicals are not of major concern as they were only carrying residual amounts.
