Tom Crockett has been playing with model trains for more than 40 years.

He started with his grandfather's small N-gauge, which has been on view in a display case in Tans Cycles & Parts since Crockett opened the motorcycle shop in North Beach 32 years ago.

Over the years, the train display and the trains themselves have grown. In the past decade, Crockett has added the larger O-gauge model trains to his collection. The display at Tans now covers an 8-by-12-foot space, and there are more trains at home, Crockett said.

Each year, Crockett dresses up the display for the holidays -- with help from shop employee Ralph Carrello -- and invites the public in to see the trains. Nearly 75 people stopped to look at the trains recently on the day of the North Beach tree lighting.

The holiday display will be up through January, Crockett said.

Tans Cycles & Parts owner Tom Crockett makes adjustments to the 1954 Texas Special train given to him by his grandfather in 1956, one of the 11 trains in the holiday display at the North Beach shop.Up to 11 trains can run at the same time on the 325 feet of track put together by Tans Cycles & Parts owner Tom Crockett and a sales associate.
