Bay seniors, bundle up the grandkids and take them on one of the geezer’s holiday favorite jaunts – the glittering hourlong evening train ride in Niles Canyon. Every year the historic trains (part of the first Transcontinental Railway built in the 1860’s) are festooned with hundreds of colored lights – it’s more magical than anything concocted by Pixar, and it’s real. The trains run Wednesday, Friday, Saturday and Sundays . Tickets are $25 for everyone over 3. The enclosed (and warmer) parlor car is $40. Through Dec.29. Many rides already sold out. A similar illuminated holiday train runs along the Santa Cruz boardwalk and through town for an hour. $28 for anyone 13 and older. $22 for anyone 2-12. Through Dec.23 only.
