This is from the "Rivet Counter" series by Scaletrains, I thought some of you may be interested. Looks like a fantastic model. In the video it's mentioned that the SD40-2 began production in 1972, and that the SD40-3 is expected to be in service for another 30 years. It's not clear if that's 30 years from the 2010 refurb to -3 specs, or from the year of the video (this year). Either way that's a long time and a lot of miles :)
