Early locomotives, switchers and special purpose Switchers SL series switchers Beginning in 1974, GE would introduce a more modernized series of industrial switchers known as the SL series. The numbers attached to each model indicate their weight in tons.
General purpose Universal Series (1956 to 1998) Four axle Six axle Six axle & Pony Eight axle Dash 7 Series (introduced 1977) Models with "A" suffix are equipped with 12-cylinder prime mover in place of the standard 16-cylinder version, with the same power output.
Four axle Six axle Dash 8 Series (introduced 1982) GE originally introduced this series with the model designation following the pattern of the Dash-7 line. After product improvements were made to the line in 1987 the official designations for models in this series changed to "Dash-8...", as shown in the list below. However, for simplicity, many railroads decided to use designations which follow the pattern of the Dash-7 line. Thus, for example, the Dash 8-40C is usually rendered as "C40-8". The "W" suffix indicates the then-optional wide-nose "North American" safety cab. For example, the Santa Fe used the designation "B40-8W" for GE's "Dash 8-40BW". The railroad continued this practice until its merger with the
Burlington Northern Railroad in 1995, and the new railroad, Burlington Northern-Santa Fe (later BNSF Railway) furthered the practice. Introduced during the Dash 8's later years were split-cooling in the radiators and electronic displays for the crews (instead of analogue gauges).
Four axle Six axle Eight axle Dash 9 Series (introduced 1993) The Dash 9 series introduced primarily electronics updates to the Dash 8 line. Also introduced was the HiAd (High-Adhesion) truck. Split-cooling was standard.
Four axle No four axle freight versions produced
Six axle Eight axle AC Series (introduced 1994) These feature the same carbody design and many of the internal components as the Dash-9 series, except they are equipped with
AC traction motors instead of the conventional DC versions. The cab air conditioner was moved from the left (conductor's) side walkway to a position under the cab floor to make space for the six traction inverters (one per axle) that supply the AC current to the traction motors.
Six axle Note 1: The "AC44i" is an 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.
Note 2: two versions: one contained a 16-cylinder 7HDL, co-developed by GE and the German firm
Deutz-MWM, rated at 6000 HP; the other a 16-cylinder 7FDL rated at 4390 HP. The units equipped with the 7FDL were a sub-version AC6000 "Convertible" and were produced to get the type into operation while the 7HDL was developed.
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.

*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.
