What I find to be odd is that I have had two different sets, both of which had the same issue, yet no one else here has reported any similar issue with theirs. My main problem has been the motor stalling upon, or a few seconds after, slow-speed startup. I have gone through a number of theories, but have proven them all wrong. At first it was suggested that the O36 curves were too tight for the engines to manage a slow-speed startup. But then it started happening on straights tracks too. Then it seemed very likely that it was a loss of signal issue. I got some great advice on that from Ameen on this forum, and learned a lot about Wi-Fi as well! After changing the channels on both my Wi-Fi router and the Legacy base all seemed well again. But a couple of days later the problem came back with a vengeance. Keep in mind that none of my other Legacy engines have ever had this problem even once after years of running, and they're still not experiencing this problem when I test them out now. So here I have experience with four different Alco PA A units experiencing, with increasing frequency, engine lock up during slow speed start up, and yet no one else seems to have had this problem. I am glad no one else is getting this aggravation, but it still seems odd. By the way, once the engines get running even at very slow speed the problem never happens. They can run all day at speed step one without stopping if they get past the initial startup.
