Cocaine and cellophane-wrapped packages of methamphetamine have been found in a locomotive at a western Nebraska rail yard.
Authorities say workers in the diesel shop at Union Pacific's Bailey Yard in North Platte found the drugs Sunday night.
UP spokesman Mark Davis said Wednesday that he could not characterize the size of the discovery other than to say it was a large amount.
The train engine was in the shop for repairs.
No arrests have been reported.
