Need a Build Date...

Hello all

I have been searching online and can't find a build date for BNSF #6990. I spotted it up here in MA today, and thought the fuel tank and trucks looked rather "un-weathered". Does anyone have a source for an accurate delivery/build date for this unit?

BNSF#6997, "Evo" ES44c4,part of the current order of 65 units from GE Erie,deliveries from the factory started April of this year.
If you can find "Diesel Era" magazine, the May/June 2012,there is a article about that model of locomotive.

Really?? That's nifty! While not an exact delivery date, now I know it is post-April 2012! Here is the photo I took of it yesterday:

ES44c4's are front line power for Intermodel trains,UPS/FedX Z-Trains,guess it was sent east to cover HorsePower-Hour's due for CSX power sent to
the LA Basin(San Berdoo/Horbart yards).

It used to be VERY rare to find foreign power like this up here in MA, especially in the northern half of the state (MA). But now with NS so involved with Pan Am, we get to have some color. Though it is only recently orange units have showed up on this particular CSX/Pan Am train.
