C40-9W w/ K5LLA leads 60 mph stacks westbound

NS 9404, a C40-9W with a rather nice K5LLA, leads a westbound intermodal train at over 60 mph, officially clocked (by me) at about 63.77 mph.

Awesome K5LLA!

Do you have a radar gun? Or how is you're measurement so precise? Nice video

I do a frame-by-frame of the video, see how many frames out of x (this varies for different videos, use whatever frame rate the video is at; I use 60 because my videos are taken at 60 frames per second) it takes for one of the engines to pass (in this case, I used the first locomotive). I take however many frames it takes and divide it by 60 to find how long, in seconds it took for the engine or car to pass. I copy that number to my clipboard so that i can paste it later. I then take the length (in this case, about 73.16666666666-and-so-on feet), and divide that by the time (the one I found earlier in seconds). That gives me the speed in feet/second. The conversion from feet/second, fortunately, is pretty straight forward. 1 foot/second equals 0.682 miles per hour. Simply multiply your result that you got by 0.682, and now you have the speed of the train in miles per hour.
