One of the Triangle's hottest holiday tickets, for the Museum of Life and Science's Santa Train, go on sale Nov. 18 at lifeandscience.org.

Since the late 1970s, the museum's miniature railroad has been seasonally decorated for nighttime trips to Santa Claus's North Pole headquarters, followed by hot chocolate and seasonal music.

This year's schedule is Dec. 4-6, 9-13 and 16-21, departures from 5:20 p.m. to 8:20 p.m. Tickets cost $12 per-person for ages 3 and up. Children under 3 ride free, but must ride in an adult's lap.

Tickets for the Museum of Life and Science's annual Santa Train are selling fast, according to museum vice president Julie Ketner Rigby.

As of 3 p.m. Monday, about 1,000 tickets remained unsold — 20 percent of the total that went on sale last week.

"It always sells out," Rigby said; last year's tickets were gone in four days.

The Santa Train runs Wednesday–Sunday, Dec. 3-7, 10-14 and 17-21, from 5:40 to 8:20 p.m. See www.lifeandscience.org.
