(Queensgate) -- The Cincinnati Museum Center will officially open the Holiday Junction display on Friday, November 8th, at Union Terminal.

And it's the 68th year for the centerpiece: the Duke Energy Holiday Trains. 

The "O" scale display is one of the largest portable sets in the world, meaning others that are larger, are on permanent display, while this one is seasonal. 

The Holiday Junction will be open until January 5th, but will be closed November 28th, and December 25th.  The display is free to Museum members, and Duke Energy customers who are not members of the Museum, can download a voucher from holidaytraindisplay.com, good for two adults and two children.
