Metro-North Railroad is operating "Shoppers' Specials" rail service Saturdays and Sundays until Dec. 26.

On Saturdays, there are 19 additional trains serving outer New Haven Line stations, and on Sundays there is one additional train serving the Upper Harlem Line stations and 21 additional trains serving New Haven Line stations (16 Stamford locals and five "east-end" expresses).

And for shoppers who don't want to stray far from Grand Central Terminal once they get to NYC, Metro-North is promoting the Holiday Fair in Grand Central's Vanderbilt Hall through Dec. 24.

The fair features 76 hand-picked vendors offering one-of-a-kind merchandise, ranging from jewelry to women's, men's and children clothing.
