An Un-boxing The New Mega Station

Update:  if you look at the text on the "new for Aug-19" product page at the TakaraTomy website, it says this:

⑤自分の持っている車両に合わせて選べる、３つのサウンドモードを搭載！（新幹線・在来線・SL)

=  "⑤ Equipped with three sound modes that you can choose according to your vehicle! (Shinkansen, conventional line, Steam Locomotive)"

All of which suggests to me that you can select the sound mode on the station control console, and nothing to do with the track that Super was questioning in the first place.
