Caption: A massive thank you to the workers at LDS who were able to accommodate me during their busy day and give me the full guided tour. GTW / LDSX 4620 sure has been around the country quite a bit recently in the last few years. Previously out in Saskatchewan at Stewart Southern Railway parked in their potential " to be used " (http://www.railpictures.ca/?attachment_id=49678) worked its way to LDS for a fresh overhaul and lease. From the Beachburg Blog Spot: Luckily, for rail enthusiasts in this area, the roundhouse was kept intact when Lambton Diesel Specialists (LDS) took over the facility in 1992 and assumed the diesel servicing operations from CN. The actual turntable is long gone, but some of the bays are still there (most boarded up) and are used for rehabbing locomotives from a number of railways. Also, the old windows have been replaced with renovations still taking place. Neat to note, some interior walls are braced with former 40' Wood boxcars with original Canadian National markings and notes for grain and other bulk quantities written on the planks.
