Andrew S I start by deciding the subject I’m going to use to make this calculation, usually a locomotive. Next, after you have decided, roll the footage until the front end/first part of the subject is right about to “hit” the edge of the frame (for locomotives, I tend to use the closest set of front steps/pilot steps). Simply count the amount of frames it takes for the object to pass, then divide that number by your frame rate. For example, if something takes 45 frames to pass and you record at 60 fps, divide 45 into 60 (it’ll be 0.75). The number you get is the time, in seconds the object took to go by. Save this number somewhere. Divide the length of your object in feet (For example, a Dash 9/AC44 is 73 ft 8 in, so you would put 73.66 for the length) by the time - this is the object’s speed in feet/second. Simply multiply this number by 0.682 (the conversion rate between f/s and mph), and you will have your subject’s speed in miles per hour. It is important that you pick a subject that passes when the frame doesn’t move (basically, no panning or zooming; A tripod also helps) for accurate results.
Awesome catches! Love the oil trains! My favorite train
ah you caught 100 before midnight blue lol
9:45 does 9019 have a K5H?
nice video
I know that Freights don't have a schedule, but do you know If freight will run on Saturdays?
I’m in Amsterdam
Nice!!! Just Subbed :)
Thanks!
Awesome! Can you explain how you clock the speed? I also use Vegas

Ayy! I think i found the right channel, You were in Amsterdam NY today right?
Yeah
@@NickyDsTrains sweet, did you see the dash 8?
Yeah, however it ended up being a wide nose after all
@@NickyDsTrains well, still a CN loco, you guys still out there? I head on the radio that a consist just lost a loco
Ex ATSF, too! I’m the only one still out here, everyone else left - traffic has been dead since about 5:40
