I have a couple of the Lionel Dash-8 505 locomotives pulling a total of twelve Amtrak passenger cars. I am running these locomotives in what I suppose (I'm an old-timer, accustomed to post-war locos) in what is known as "conventional" mode. I do not have TMCC or Legacy controllers. I am simply applying power to the track via a Lionel 6-32930 ZW Transformer with two180 Watt Bricks (one for each track). The issue that I am seeing with the locos is that when the amount of power is adjusted, with the train in motion, the train comes to a virtual stop, and then starts back up again with the new power settings. This is an issue, especially if the train is on a long curve, as the sudden increase in power (as seen by the loco) causes a severe jerking motion when it restarts, often derailing one of more of the passenger cars. I have the Odyssey mode turned off. In fact, all switches are in the off position, with the exception of the run/prog switch, which, I believe, is in the run position. Any idea what is causing both 505s to perform like this. Not only do I tire of putting the cars back on track, but each time they derail, they pick up little nicks and scratches.
I run, with the exception of this Amtrak, exclusively post-war stuff. Have never seen this type of behavior before. Any and all help would be appreciated.
