Metro Transit is offering discounted rides on buses and trains to fans heading to Twins games at Target Field this season.

It's new Twins Family Pass will allow two adults and up to three children ages 6 to 17 or seniors 65 and older to ride round trip to the stadium in Minneapolis for $8.50 on weekdays and $7 on weekends. Passes can be used on buses and the Metro Blue and Green light-rail lines.

Passes also can be used on the Metro Red Line, which runs along Cedar Avenue from the Dakota County suburbs to the Mall of America. From there, fans can ride the Blue Line to Target Field.

Passes can be purchased in advance at the Metro Transit website or on train station platforms on game day. Passes purchased at vending machines are good until midnight on the day of purchase.

Metro Transit also has family passes available for Northstar riders, although they cost a bit more. Prices range from $11 to $20 depending on which station fans board. Northstar trains will operate for all Twins home games in 2014.

The agency will continue operating its Twins Express Bus service from the County Road 73 Park and Ride Lot on I-394 in Minnetonka for all home games. Route 679 buses to Target Field will run every 15 minutes starting two hours before game time. Return trips will start two hours after the game starts and operate until an hour after the final out.

The new Twins Family Pass is good on the Twins Express Bus service.
