After 54 years it looks like history is catching up to Mattel. While they weren't solely responsible for Lionel's downfall in the 60's (you have to give credit where credit is due and Lionel was its own worst enemy) one of their (Mattel's) two flagship products isn't doing to well.

It will be interesting to see if Barbie makes it to retirement. Lionel had considered itself a toy company that made toy trains which was fine as long as people wanted toy trains. Mattel has a few more aces up their sleeves but it does go to show that nothing lasts forever.
