Unlike cramped planes and polluting automobiles, trains provide a hassle-free commute and better opportunities to network with strangers. Enjoy the romance of the rails with today's Groupon: for $10, you get a one-day, unlimited Metrolink pass (up to a $45.50 value) that's valid for use on any of the 16 days of Christmas, which stretch from Saturday, December 18 to Sunday, January 2.

Metrolink's efficient, dependable rail service threads through a total of six SoCal counties, sending out seven raily runners to connect its network of 55 stations. Venture from Ventura County to North San Diego and all stops in between with a one-day pass, which gives the bearer unlimited access to trains and one complimentary rooftop brawl. Metrolink's comfortable double deckers satisfy latent older-sibling impulses to claim the top bunk. Due to yuletide shenanigans, there will be limited service on December 24–25, 31, and January 1, so read up on holiday service changes here; if you plan to ride on the 18th or 19th, watch out for the Holiday Toy Express, which steams in from the North Pole every year to drop off unwanted elves.

The value for this deal was determined by using the round-trip rate from one end of Metrolink's Orange County Line to the other, but customers will get an unlimited number of rides on the day they redeem, on any line(s) they choose.
