There is a problem with some of these. My new Legacy Reading and Northern (Blue one) will on start up decide on it's own how much volume will be present and it changes each time.
A little startling when it comes to life at FULL volume.
On start up it may come on full volume or no volume at all.
Once I adjust the volume, all is well until the next session.
A new board from Lionel did not solve the problem.
I suspect software issues.
