In the mid-90s, Norfolk Southern didn't want increasingly high-horsepower locomotives, nor did they want wide noses. GE satisfied their request with the C40-9 (Dash 9-40C), the last standard-nose engine GE produced.
Its most obvious distinguishing feature from the C40-8 it replaced are its high-adhesion (known to some railfans as "rollerblade") trucks.

After the C40-9, NS finally ordered its first widenose engines. (Deliveries of standard-nose SD70s would continue for some time.) They still didn't want the higher horsepower of the C44-9W, so GE built the C40-9W.
The C40-9W can only be distinguished from the C44-9W by its headlights. The C40-9W has cab-mounted headlights, while the C44-9W has nose-mounted headlights.

The C40-9W was replaced by the ES40DC.
Fan of Conrail... also transition-era PRR, 70s Santa Fe, BN and SP, 70s-80s eastern CN, pre-merger-era UP, heavy electric operations in general, modern EFVM and Brazilian railroads in general... why bother trying to list them all?
