This weekend is the final chance to see the Trains at NorthPark before they are put away until next fall.
Each holiday season, the "most elaborate toy train exhibit" in Texas is put on display, covering more than 4,000 square feet and 1,600 feet of track.
The tracks twist and run through cityscapes across America, including Dallas, New York City, Washington D.C., New England, the Grand Canyon, San Francisco and more.
The latest news from around North Texas.
Added to this year's exhibit are Dallas' new Margaret Hunt Hill Bridge and a little Big Tex at the State Fair of Texas.
The exhibit is open between 10 a.m. and 9 p.m. on Saturday and from noon to 6 p.m. on Sunday. Children under 2 are free, but it's $6 for adults and $3 for kids and seniors.
The trains are located on the 2nd level of NorthPark Center, near Barneys New York.
Since 1987, the Trains at NorthPark have raised money for the children and families served by the Ronald McDonald House of Dallas.
