On January 24, 2005, as part of its tenth anniversary celebration, the Burlington Northern and Santa Fe Railway was renamed BNSF Railway, which adopted a new logo. By March, the logo had been applied to the sides and fronts of six ES44DCs, which were otherwise painted in the "Heritage II" scheme, except with black replacing dark green. Slight differences were present on the six locomotives, and on April 11 BNSF officially chose the design it had applied to No. 7701. The "New Image" scheme is also referred to as "Heritage III", the "Nike Swoosh" scheme or simply the "Swoosh" scheme. Some railfans also refer to the logo as "The Wedge" scheme.
