get the type into operation while the 7HDL was developed. **Note 1: The "AC44i" is a export version of the AC4400CW locomotive for Brazil. In that country, these models are the first to use AC (Alternating Current) in their operating systems. The first units were made in United States on 2008, and the other sequential units made in the local plant of GE, in Contagem municipality, Minas Gerais. Evolution Series (introduced 2005) The Evolution Series locomotives replaced the Dash 9 and AC series in North America and exceeded the then new U.S. EPA Tier II emissions standards that took effect in 2005, reducing nitrogen oxides emissions by over 40% and improving fuel consumption as well. They use the new GEVO engine (based in part on the 7HDL design) which produces the same power from twelve cylinders as previous locomotives' 16-cylinder 7FDL engine. Both AC and DC Evolution Series share the same carbody design. The radiator section "wings" are divided into two parts with differing angles. Six axle Eight axle *Note: GE Brazil has an order for 46 units of this model for Rumo Logística, which will be delivered during the year 2017. Is the most powerful narrow gauge locomotive in the world. FLXDrive The FLXDrive Series of locomotives are GE's first battery-electric locomotives, using a similar design to the Evolution Series, with the exception of a diesel prime mover. The FLXDrive series was introduced in late 2019 with one BEL44C4D demonstrator unit, but other FLXDrive variants are planned for the future. Six axle PowerHaul Series Six axle Passenger locomotives While primarily a builder of freight locomotives, GE has on occasion been called upon to construct passenger models for specific customers. The most recent is the P42DC, ordered by Amtrak to replace the aging EMD F40PH. Additional units have been built for Via Rail Canada.
