A Norfolk Southern C44-9W would add some more variety, liveliness and activity to the Horseshoe Curve Route, as well as improving realism. The train could appear in 1 or 2 liveries: One with a white bar above the front cab, and one without it. These trains would almost certainly run on the route in real life and would add to the route and finally make it feel truly complete. Above is a C44-9W Alternatively, A SD70ACC could also be added as a loco DLC to HSC. Once again, it would improve realism, add to the line and comes with multiple liveries. This would include the special yellow scheme, as well as the standard NS black. Above is a SD70ACC Above is the cab of a C44-9W (Sorry about the low quality, it was the best image I could find) If either of those engines aren't fitting for TSW3, The final loco that I can suggest is the AC44C6M, DC to AC traction Locos. These also come in some very unique and special livery sets, with some very colourful units that appear on the railroad occasionally. Above is a special AC44C6M Livery
We need them tbh. Little edit: Bring the C44-9W with all 3 liveries: Thoroughbred (old logo and fully black cab front), Normal (you know, as seen on the ES44AC) and Whiteface (fully white cab front).
Add an NS SD70ACU and SD60E as part of an NS Rebuilt Diesel DLC Pack. A GP59(E or ECO), SD40-2 with the Admiral Cab, SD33ECO, and SD40E would be awesome to see as well. NS had C40-9s with narrow cabs (they have since been rebuilt as AC44C6Ms), but the original version would be cool to see in game.
Bring them on and C44-9W can be reskinned to spawn a Cajon Pass BNSF Union Pacific version Sherman Hill & CSX Sand Patch Grade
