Last picture I took from an old wooden bridge, that this 3 unit powered mixed frieght just barely clears, before I put down the camera and took a page from my kids. Lying face down with eyes closed maybe 5 feet above these units, I got blasted with the heat from the fans from all three units. Great rush!

PS: that first oversized box car (white stripe on upper edge) made me jump up, man it was close - chicken!
