Last post on this as don't want to get off topic.
John, send me an e-mail address I could send a video to you and you can see on the same track with the same train the difference in a 2 or 3. I think the difference in what we may see are the conditions the engines are used in, I know we both believe we are right and may be in different conditions why that could be. The number of cars are not created equal, it depends on what cars you are pulling. I have Atlas well cars for my stack train and while it's not the longest train being pulled, it is very heavy and has very little slack in the train, so it's harder to pull and start than trains 30 cars longer. It's not a power issue to the track or other factors or the PS2's would have the same power issue and both would do exactly the same thing as you suggest.
I only shared this opinion because I have seen the same issue as the author to this thread stated. I would also hope we can all share our experiences to help others.
