I bought an acela loco with 5 cars about 5 years ago.  I love the dcc...  The engine never pulled more than four cars well so I put it away and waiting until i could build it a layout it deserved.
   I am building a new layout(8 months into it now) with all 22" curves.  The acela is worse.  It barely pulls two and is spinning in place.
   On the same track I have a tiny 40 ton switcher pulling a full Broadway Limited with no problems.
What can I do to save my Acela?

Thanks,
