I've been searching around with no luck on this one. I'll try to explain as best I can.
I have a Lionel Lionmaster SD90mac that I run in conventional. I usually keep the Railsounds switch off, but I use a battery anyway. The reason for the battery is that When I blow the horn at very low speed, it doesnt work without the battery.
But here is where it gets funny: Keep in mind sound is switched off. When I stop the train and shut off the power to the track, even switch off the surge protector my transformer is plugged into, The railsounds starts its start-up sequence. It lasts for about 2-3 seconds then stops.
Any ideas?
Thanks.
