http://www.railpictures.net/viewphoto.php?id=102830 This was the best lash-up of my life! It consisted of 4 BN SD40-2's and a BNSF SD40-2 doing track speed 70 MPH with a westbound Manifest!

Cant do 70 MPH with those kind of cars. 40 if those bulk head flats are empty.
When there loaded i hope. Just at a first glance, i doubt that train is good for 60, 50 or 40 i bet, but not 70.
Humm crazy. Maybe its not as windy there as it is here. SD 40's are my favorite. There the most fun, and they do as there told. 
Well drop the BNSF logos keep the white stripes on the noses and I will show you my typical train in my youth! Loved watching that many SD-40-2's slug through Orion on their way to Galesburg. Match up s like that were common on ore trains and some coal ( got a lot of C 30-7's and older than dirt U33 C's on coal) and a few just junk trains. Ah the memories of mean green machines.( ok to show my age I vaugely remember GN< SP&S, NP and other merged roads of the BN making their way through Orion as a young kid.
Nice if you like SD40s, and there's nothing wrong with that. And it is a very good photo.
But either you're new at this or you need to get out more if that's the greatest you've ever seen. I come from the era when the things first took over.
Some of my favorites are:
Five SP passenger F's in freight service screaming away in the last notch on a steep grade.
Six BN C424s and C425s on an Inside Gateway freight in 1972.
12 SP units of 9 models on a freight circa 1985.
SP SD45 rebuild 7399 in experimental new-style Daylight colors leading 9 GP9s and SD9s up Donner Pass after Roseville ran out of power.
SD40s don't impress me because they are thick as flies here in northwest Ohio.
