I have recently noted a few differences between US and Canadian diesel locomotives. One noticeable difference is that the cabs of the Canadian locomotives seem EXTREMELY comfortable, way more comfortable than the American standard. I believe that CN uses the term "Comfort Cab." The cabs have small stoves, microwaves, and are quiet. The seats are different too. Unlike the leather chairs that most US cabs have, these chairs are big, plush, and comfortable. They also need to be well heated because of Canada's brutal winters.
I have seen cab ride videos in these locomotives and loved it for a specific reason. One of my favorite feelings is when it's snowing hard at night, and you're all warm and cozy looking out the window into the bitter cold. So this nighttime cab ride in a blizzard was great.
The engines on the EMD power seem the same as US power, but the GE power sounds different from American GE's. The engine sounds a lot tougher than the sounds I hear from idling locomotives here. The only thing I can compare it to is an ALCO. Maybe it's me but they sound somewhat similar.
I will show you a video of a Trainz model. I know it is a simulator, but the cab, exterior, and engine sounds are extremely realistic, and the cab is detailed down to every small feature.
If someone can inform me why the engine sounds so beefed up, or why Canadian cabs are made that comfortable please tell me!
