This topic may appear "a day late and dollar short", or more like a year late since it was roughly a year ago that the Legacy Acela sets were released, however I could not locate a review of the unique Polar Express set on this forum, nor any stand-alone topic that discussed the fact that Lionel made it in the pale (wrong) blue hue. This is surprising given the high cost of the set and add-on cars.
I had mentioned that the colors were off in a separate thread that discussed the Vision Line Reindeer cars, however, and posted a picture (and re-posted below) of a PE Acela car, Reindeer car, and correct colored heavyweight PE car.
While this may very well be a lost cause, I have sent Lionel a detailed letter noting the color discrepancies. I am curious if anyone else contacted Lionel about the PE color discrepancies on the High Speed Acela sets?
We're coming up on a year when the PE Acela sets were released, and while the color differences may not be a warranty issue per se, it is nevertheless a matter that if we have the right to request assistance with. And, while I would prefer to have the darker and correct blue colored high speed PE train engines and cars, the fact they're made in the wrong colors doesn't ruin my enjoyment of them. The fact that I am still paying them off via credit card debt kind of sticks in my craw a bit, however.
If anyone feels the same way, then I encourage you to write to Lionel asap. It wouldn't hurt to include a copy of your sales receipt, too.
