The Norfolk and Western Railroad ( N&W ) is by far one of the most iconic railroads in the United States. Known for it's continued use of steam until 1960, the longest time any Class I railroad in America had used steam, and for being responsible for some of the greatest giants of steam such as: the Y-6-B's, Y-3's, and J's. Much of the railroads popularity came from famed photographer O. Winston Link, and his recordings, and night time photographs, taken along the N&W. This railroad is a true icon in steam railroading, and though the J-class might be hard to implement into the game due to it's copyright issues, there are still plenty of locomotives to choose from such as the M class 4-8-0's, or the K1 4-8-2's. There have been several N&W steam locomotives in operation in mainline excursion service since the demise of steam on the N&W, the most popular of these locomotives include #475, #1218, and the most famous of them all, #611. This route would, in my opinion be a popular addition to Train Simulator, and I hope that this suggestion get's taken into consideration as a DLC in the future.
