It's certainly not Product Placement though, which may explain why the DLC costs so much.
Bland-Name Product: Averted, as the rolling stock are real-world replicas, down to the interior.Rail Works and its sequel provide examples of: Rolling along in a 100+ car train? If you stop the camera to look outside of the train at a static location, you'll find it does take several real-world minutes for the entire thing to pass.
Unlike other vehicle simulators of a similar type, RailWorks features to-scale locations with no space-time compression involved whatsoever.
You can also control the train using a variety of input devices, including the controller, keyboard, and if you want a full on experience, using the mouse to look in the cabin and manipulating the appropriate control. If you're a commuter train, you'll have to adhere to a tight schedule and Automatic Warning Systems (designed to ensure you're paying attention). Of course, you can't just simply hit forward and let it run, you'll also have to obey speed limits and semaphore signals. Depending on the type of route, you'll be picking up and dropping off commuters to delivering cargo. You control a variety of trains from steam driven trains, diesel trains, to electric trains. Aside from that, the game's premise is the same as the other train simulators.
