Spotted in Colorado Springs on Sunday-a train load of wind generator blades, hubs, and main housings (not sure what the proper name of that is). Those blades are BIG-about 1 3/4 flat cars long! Pics aren’t too good…cell phone, and the sun was behind the train. 
Nacelle is the word you were looking for, and expect another train in about four days.
Any idea why they put two nacelles on a 8-axle heavy duty flat, instead of one on a regular flat?
I handled a few of these trains. http://youtu.be/mSoSHAT1jL4?list=UUPx_Z9FvKmC-YR1XRcXfrEg
Can’t take the video whilst running…
Ride control and car lease cost.
yes, ride control; no, car-lease cost, because heavy duty flat costs more than two regular flats
VESTAS
The nascelles come from Brighton, CO (UP - DP/Cheyenne Line)
The blades and rotor hubs come from Windsor, CO (OmniTrax GWR) on the former BN/C&S Greeley Sub…Right now they interchange at Ft. Collins (sometimes Loveland), but eventually will connect at Greeley when a wye is rebuilt (virtually abandoned by BN who had no need to connect w/ former C&S predecessor GSL&P owner UP)
The towers come from Pueblo/ Southern Jcn (UP/BNSF)
The 60-80T general service flats do not have the decking or snubbers/suspension to handle the lateral loads. The 100-150 ton flats can handle the loads cleanly on top of the kingpins w/o binding.
We see those in Canada quite often. I once saw windmill parts on a barge in the Rhine river at Cologne.
