I was having some issues with running my MTH locomotive using the remote with TIU. If I pressed the horn, then one of the other horn buttons, or any button right away while going at a faster speed the remote would say, signal lost or check track. It just seemed like the system was unreliable. (The track was not dirty) But then I started to Wonder if this was due to the z500 transformer. I'm running 5 passenger cars and was wondering if it was drawing more than the z500 could put out. I just purchased a z1000 and ran the train without experiencing anything weird. But the signal loss when using the z500 wasn't constant, sometimes it would be fine. But like I stated above, it also depended on how many buttons I pressed on the remote and how fast the locomotive was going. At higher speeds the train would lose signal and if I dialed the speed down and waited for several seconds, the signal came back. So I'm hoping the new z1000 takes care of this. Does this make sense, what I'm asking?
