I brought this up over on the ATLAS Forum when they were discussing this release. The new BNSF logo is on ES44 diesels and not AC4400 ones. The "Evolution Series" were delivered as replacements for the AC4400's in early 2005, and the new paint scheme was added to them. Wikipedia says this about them: <br /> <br /> <br /><i>"The Evolution Series locomotives very much resemble the previous Dash 9 and AC series safety cab models in superficial appearance. Both AC and DC models have the large cabinet behind the crew compartment on the left-hand side which on the AC models houses the traction inverters. The previous Dash 9 models had a much smaller cabinet here than the AC models did. It is thus difficult to distingui***he DC and AC versions of the Evolution Series. <br /> <br />Above this cabinet, at the top of the cab end of the long hood, there are four ventilation openings where previous models had three. <br /> <br />The lower-roofed engine compartment is shorter than on previous models, thanks to the shorter prime mover. Earlier models had substantial space between the exhaust stack and the radiator "wings", and this is lacking on the Evolution Series. <br /> <br />The radiator section is significantly longer than the previous models, and appears more bulky. Unlike the earlier radiators, it overhangs at the rear. The sloped underside has two sections with different slope angles, unlike the single previous angle. The front end on top has a raised 'hump' - this area houses the enlarged intercooler system fitted to these locomotives. <br /> <br />Overall length appears to be shorter, but is the same, and the trucks and fuel tanks are identical. <br /> <br />On some Locomotives, a new "BNSF" logo replaces the other one. It appears as BNSF with a triangle extending under the legnth of the letters."</i> <br /> <br />
