Cochrane Yard, July and August 2002. With Ontario Northland's introduction of the 2100 Series SD75I, upgrades are deemed necessary to basicly every stretch of track and switch frog that the oversized locomotives run on while on their daily routines. The job of upgrading rail and switch frogs at Cochrane Yard will be handled by Steel Gang 92. Here's a photo of the consist of Steel Gang 92 at Cochrane August 2002.
