Early on a August Friday morning Strasburg's former N&W M-class 475 switches the freight yard at Strasburg after returning from the NS interchange. No. 475 and crew have just spotted another biodiesel load and are running high to spot the KCS boxcar loaded with plywood from Louisiana for unloading on an adjacent track. Steam powered revenue freight moves in 2012 are hard to come by but have been a twice-weekly occurrence at Strasburg this Summer.
