When I first tried the Shay on 4' curves it did not seem to work.  Tried it again today
and had no trouble with the 4' curves.  Guess it will be OK Locked.  Sure do wonder
why it showed rotated in the video. 

The video is  the DVD that came with the unit, showing
how to lubricate the loco. Also showing some of the history
of the Shay loco.

No.  This is the video for the 3 truck shay. It show the water bunker
detached from the loco.

I went back and looked at the video again.  When he is putting the water bunker on
it's side, the power truck is rotated.  Maybe it is that way on the newer Shays.l

I recently purchased a new in the box 3 truck shay.
I noticed that the water bunker power truck would not
rotate. I contacted Bachmann service and was told it was not
supposed to rotate. Watching the video on how to lube the loco
it shows the truck rotating.  Can someone please help me
get it to rotate. Thanks
