N&W Class J 4-8-4 I started by doing a skin for the Northern 4-8-4 that converts it into the N&W Class J, perhaps the most perfect steam engine ever built. However, since I wanted my AI company to make use of this skin and not just use the default Northern, I asked Bombadiere to help me out by creating a stand-alone engine of it. This afforded the opportunity to create a truly modern steam engine, one which competes favorably with the F3, and which isn't even available until 1941 (the game's northern begins at 1926). The image below is outdated; I have made a few minor tweaks to the skin since then. DOWNLOAD THE N&W CLASS J - as ZIP file, you must unzip and then place the PK4 file in "UserExtraContent", the rest into "EngineTypes"
