I found myself disappointed when I was looking for locomotives I knew in real life in the simulator and found that you have the control interfaces for the systems that control the locomotives' engine idle stop/start that is used for saving fuel and polluting less in real life. The reason I was at a hunt for this is because I love the sound the engine of the SD70ACe does when it is in idle, when it shuts down automatically and especially when it starts back up and when it slowly revs up to start the air compressor. I was suprised to see the computer in the cab of certain liveries and that they were not actually performing their function... CP (where I work) has that feature on most of their fleet including their 4 axled GP models, but it does not sound anywhere as cool as their SD 6 axels...
