I have spent 5 days running my Legacy Polar Express and there are a few things I wanted to share with others. Don't get me wrong, the locomotive is fantastic and I'm excited to have it, but there are a few things I found interesting about it.
I watched a little this morning. Did a quick scan and will watch the rest tonight. I asked a while back if the Cab3 App could be setup to get some of the sounds customized in the side panel. I was told it wasn't. Not sure if this is a technical limitation but I got the impression it had something to do with maintaining Cab2 compatibility. The iCab App worked the same way.
Hopefully in the future, because it is software based, the Cab3 could have added control for special engines like this to trigger certain sound sets within the random dialog.
