I'm fairly new to Legacy operations, but I've been having issues with running my 20296860 Vision Line Stock Cars, 2131020 Legacy PRR S1, and 2131270 Legacy Pacific. As of late when I power on track power, the locomotives will automatically start and not respond to the Legacy remote. I've attempted to fix the issue on different track, but the issue still persists. I tried just using Bluetooth control, and everything seems better with the S1, but the Pacific will stop, blow its whistle, then restart on occasion. I have been able to control the locomotives using Legacy, but after a while they'll stop, the headlight will blink, and then they're stuck in neutral and won't respond to the remote. I just want to see if anyone has any ideas on how to fix this.
Just for reference, I'm using a Z-1000 transformer hooked up to a TIU with the Legacy unit wired to the output of the TIU as outlined in a YouTube video.
Thank you in advance for any help you can provide.
