AT-GrAde/SurfAceRoute located at street level.
commuTer rAIlAlso known as “Sounder “in the Central Puget Sound region. A form of daily long distance travel by rail mostly during peak commuting hours. Tracks are usually shared with freight or long-distance passenger trains (Amtrak) and are run by either electric or diesel power (diesel in our region). Typically there is one station in each town or city.
elevATed/AerIAl STrucTureStructure that is raised above the ground; a bridge.
GuIdewAyTrackway of an exclusive rail facility dedicated to the conveyance of train vehicles.
GrAde-SepArATedSeparation of transportation facilities, such as streets and rail lines, in order to eliminate potential conflicts for right-of-way travel.
column/pIerA column or pier provides structural support to an elevated structure. (Tukwila elevated track)
operATIonS And mAInTenAnce (o&m) fAcIlITyFacility designed for the storage and maintenance of transit vehicles. An O & M facility for light rail operations for East Link may be 10 to 20 acres in size and include tracks for outside storage and a building for maintenance and cleaning of vehicles, as well as tracks leading to and from the facility to the main line.
overheAd cATenAry SySTem (ocS)System of overhead contact wires that supplies electrical power to a light rail car.
plATformCan be located on either side of rail tracks or between them. Customers use platforms to enter or disembark trains. Platforms may have ticket vending machines, maps and schedules available.
mezzAnIneAn intermediate floor between main floors of a building. In an elevated train station, the mezzanine would allow for the connection of two loading platforms without the need for crossing railroad tracks and could include ticket dispensing machines, information kiosks and rest areas.
