INGERSOLL - Workers protesting the lockout of Electro-Motive employees in London were continuing to block a Caterpillar locomotive in Ingersoll, Ont., on Wednesday night.

Reports from the scene said the train had been allowed to move on earlier Wednesday after police intervened.

But a spokesman for the Canadian Auto Workers union said about 80 members remained blocking the train and plan to stay on through the night.

The locomotive, which was built at the London plant, was initially held up at a downtown crossing on Thames Street by about 100 people.

Provincial police arrived at the scene but Const. Stacey Culbert said they were there to ensure public safety, adding no charges were likely.

A CAW spokesman said it's believed the locomotive originated in Stratford and was headed to Salford, just southeast of Ingersoll, to be painted.

About 450 Electro-Motive employees have been locked out since Jan. 1. Caterpillar is demanding steep wage cuts and benefits concessions.
