The model-train exhibit opens at 7 p.m., after the lighting of the town Christmas tree on the adjacent Town Hall Green, and it continues through New Year's Eve.

The train show kicks off a series of holiday-related events planned by the museum that include a candy-house-building program, puppet-making theater and a candlelight tour of the historic Ogden House.

Model trains in the display wind through holiday scenery and around a Christmas tree, the museum said in a news release. A camera mounted on one of the trains will provide visitors a track-level view of the scale-model route.
