Freight Train Passing By

This is about 2 minutes total. It is of an approaching long freight train passing about 100 yards away in it's entirety. Train was doing around 45 mph. There are no other background sounds, no traffic, no crossing alarms, no street noise, no airplanes, no people, etc. There are three diesel electric locomotives in the front, then about a mile of freight cars, then one diesel electric locomotive "pushing" from the rear (it almost sounds like a jet engine!). Recorded alongside the tracks in open west texas desert! recorded using a panasonic dvx200 with a rode shotgun mic & deadcat. Audio extracted from the video file.
