Going to put the YouTube videos that I've posted of my Bachmann HO Amtrak Acela set here.
First one is from back in March at the layout of one of my 3 clubs (SFRM). Didn't have the pantographs raised because of the low clearance at the tunnel portals. I ran the Acela in both directions and according to the speed trap topped out at 98 mph as that was the max 128 Speed Steps the NCE DCC Controller would allow. Why Bachmann didn't include sound with this DCC model is beyond me, especially for the MSRP that they are asking for it.
Second video is from last month on my ceiling layout
And then this one is from last week on the East Coast HO Exhibitors Society (ECHOES) - one of my clubs - modular layout that they had up at train show being held by another one of my clubs (SFRM). Wonderful long runs (I'm guessing around 300+ feet) that I got to see my trains stretch their legs, so to speak.
