(Ice) hockey: One of the two 12-inch wide blue lines painted on the surface below the ice at a hockey rink. There is one 60 feet from each goal. The blue line divides the central, or neutral zone from each team's defensize zone.

The blue line is used to determine offside, which is a violation of movement rules that stops play. The blue line is also used to determine if a two-line pass was made, which also stops play.

The 'blue line' is also used informally to refer to a hockey team's on-ice defensive pairing, or sometimes the entire set of defencemen. Once could say, for example, that "Borje Salming was a stalwart member of the Toronto Maple Leafs' blue line."

As for the Metropolitan Area Express (MAX) light rail system operated by TriMet in Portland, Oregon, the Blue Line comprises the first two light rail lines built in the metro area. The Blue Line was not so named until the addition of the MAX Red Line, as the MAX system had only one line beforehand. The MAX Blue line travels from central Gresham through Northeast Portland, the CBD, under the West Hills, and through Beaverton to Hillsboro.

The first segment of the Blue Line (later to be known as "Eastside MAX") was constructed in the early 1980s and opened in 1986. This 25-kilometer segment was built with $178.3 million in federal funds diverted from the defunct Mount Hood Freeway project, as well as state and local funds contributed to the total cost of $214 million (1986 dollars). It runs from the Cleveland Avenue station in downtown Gresham along Burnside to the Gateway Transit Center/NW 99th Avenue. It then continues along Interstate 84 (the Banfield Freeway) to Lloyd Center/NE 11th Avenue, then along NE Holladay Street to the Rose Quarter Transit Center, across the Steel Bridge, and along NW 1st Avenue and SW 1st Avenue in downtown. It then splits onto two streets, with westbound traffic travelling along SW Morrison Street to the Galleria/SW 10th Avenue stop in downtown Portland, and eastbound traffic travelling along SW Yamhill Street from the Library/SW 9th Avenue stop.

The second segment of the Blue Line (originally called "Westside MAX") was constructed in the 1990s and opened in September 1998 (except for the Civic Stadium/PGE Park and Kings Hill/SW Salmon stations, which opened in September 1997). Construction of this 30-kilometer line was delayed by unexpected difficulties boring and blasting the 5-kilometer tunnel under the Vista Ridge; blasting was halted after neighbors on the hill complained of noise and vibrations. Costs in boring and blasting the tunnel contributed to the large $963.5 million cost of the project. The line continues from the original Eastside MAX line along SW Morrison and Yamhill streets to the PGE Park station (formerly Civic Stadium), turns onto SW 18th Avenue and soon onto SW Jefferson Street, and then shortly after enters the tunnel. The tunnel exits alongside US Highway 26 (the Sunset Highway), which the line then travels along to Oregon Highway 217, then through downtown Beaverton, and along an old railroad right-of-way to downtown Hillsboro, where the line runs along SE Washington Street to the Hatfield Government Center.

The CTA's Blue Line connects O'Hare International Airport with Chicago's loop and West Side. This line runs through both subways, elevated tracks, and at ground level.

The O'Hare and Forest Park (formerly Congress) branches run 24 hours a day, 7 days a week. The 54th-Cermack (formerly Douglas) branch, however, only runs between 4:00 am and midnight on weekdays, with no overnight or weekend/holiday service. Passengers who are travelling during times when the Douglas branch is out of service should either use trains to Forest Park, or take the bus.

There is a project underway to renovate the Douglas branch of the Blue Line (called Renew the Blue). As such, stations may be closed for renovation. Though track work is only done at times when the branch is not in service, passengers may still experience delays. Call 836-7000 (from any local area code) for travel information, or 1-888-YOUR-CTA for customer service information.

Below is a text map of the Blue Line's route. Please keep in mind that it is not to scale. Traffic is two-way in all areas of the map. Sections of the Blue line that are subway are indicated by ·, and non-subway portions use - or | to indicate the route. North is up. Stations are marked with either an o or a (T). The latter represents a free transfer station. Mouse-over the (T) to see which lines you can transfer to at that station.

Things to note:

  • During the second half of 2006, the CTA will be running a trial routing plan on the Blue Line. The Cermak/Douglas branch, instead of merging with the Forest Park/Congress branch, will continue north to Lake Street (Green Line tracks), where it will then turn east and terminate in the Loop. This route is shown as *s, but stations along it are not marked. For more information, please see the Circle Line writeup.
  • All stations have some form of warming-shelter on their platforms. Usually, there is a bus-shelter with heat lamps. Though these are not the best in the world, they do provide some warmth and protection from the wind during the winter.
  • Most stations have Pepsi vending machines (20 oz $1.00), and some also have convenience stores.
  • The CTA uses electric trains, which run off of power from a third rail. Therefore, it is imperative that you stay off the tracks!
  • All train cars have an intercom system to the motorman, located on a panel next to the wheelchair-accessible seat by the cab of each car. This can be used in an emergency, or by customers with disabilities to alert the motorman to wait until they have exited the train.
  • Though all runs are accessible, all stations are not. In addition, most runs have some accessible and some non-accessible cars. For those who need full-width doors, either for wheelchairs or luggage, accessible cars are often located in the front and back of a 6- or 8-car run. The middle two or four cars are older, and have blinker-style doors, which do not provide enough space for a wheelchair to fit through.
