One more thing you can do if this hasn't occurred to you, although this too will not give the automatic effect you desire.
While driving the train go into #8 view and race the camera ahead of the train as far as the sim will allow. Then drop down to the level you wish to be at and wait. The train will come past you eventually, how long depending of course on train speed. Turns you into a sort of pseudo-rail fanner.
It's also nice when driving a passenger train. You can race ahead to the next station, as soon as the sim allows you to get far enough ahead of the train, and be one of the passengers watching your train pull into the station, discharge and pickup passengers, etc. While you're standing on the platform you can observe your train's progress on the route progress bar in F3 or F4 view and center your train on the station icon for a "perfect landing." (Apologies to Buzz).
Also looks good standing at road crossings - watching the gates lower and the lights begin flashing as the vehicles begin stopping, then hearing your train approach as you blow the horn/whistle, culminating in your train passing by. A thrill a minute!
