CAT-illac A set of Caterpillar 325D excavators work in tandem to lift and move a section of track into the void created by the removal of the old switch from the mainline into the Vulcan Materials' Quarry. In a few hours this track will have been connected to the mainline and tamped for train movements. All of this work is for the completion of the new CTC controlled siding at Loachapoka.
