OK now that the work day is over I played around with the PFA button on the DCS Commander. This is the one to turn on the freight sounds ... I noticed that if you press it when in neutral it starts like I said before however, if you press the dir button after the first announcement, it goes to the next one. There is about 4 or 5 of these. If you move the throttle wheel during these it does not respond. Once the announcements are done it gives the all clear and the bell sounds, you hear the coupler slack and the engine starts in the direction it was going before you pressed the PFA button even if the arrow is not facing the right way since you press the dir button to hear the next announcements. That was a mouthful ...
I did press it while the train was running and it came to a stop and started like explained above ... not 100% sure on what actually happened but you get the idea.
Tried the train wreck button STW, nice touch and when it's done making the sounds it turns the engine off.
Not sure how the doppler works but I try that later on along with other functions.
So far I very happy with the MTH engine. I have been looking at it in the store for a while and was worried that I would have a collision since I only have about 3/16" clearance when the trains pass each other on my double track (Fastrack 036). However after almost purchasing a Railking switcher because of this, the store employee pointed out I was measuring incorrectly. I figured from the center of the truck to the end of the body. He pointed out to me that actually this 6 wheel truck has the pivot point further to the front from where I was measuring. Although he did not guarantee it would fit, he said there would be a very good chance and he was right. It actually clears by about 1/4", that's more than the 027 engines I have
I haven't tried the smoke yet. When I was running in conventional, I turned the pot counter clockwise as per the manual to turn it off. I tried to remove the grill as per the manual and try as I may, I can't get it off ... I called the store and he advised me to just add the fluid thru the grill and wipe it off when done. I asked about the smoke when I purchased the DCS Commander from another store today and was told that I could leave the pot turned to off and the smoke button on the DCS Commander would override it. Not sure I want smoke but I may wait until the weather warms up so I can open the windows to test it.
