Caption: Pulling down track CL-07, CN 5730 leads 435 past an armada of track machines waiting to begin the night's work on the north track of the Dundas Sub. CN is conducting a major trackwork project including tie replacement, new ballast (note Herzog loaded ballast train at left) and new pieces of rail. These days, CN 435 has been running with three engines as it now forwards crude oil loads from Mac yard to Brantford, where the oil is interchanged to SOR for movement to the IOL refinery at Nanticoke.
