Editing Columbia, Maryland (section)

=== Transportation ===
==== Public transit ====
Columbia's initial plan called for a [[public transport|minibus system]] connecting the village centers on a distinct right-of-way that allowed denser development along the route.<ref>{{cite book |title=The Community Builders |author1=Edward P. Eichler |author2=Marshall Kaplan |page=69}}</ref> The routes were not constructed, though minibuses were operated by the Columbia Association under the name "ColumBus". These were eventually taken over by Howard County. Six [[Howard Transit]] bus routes served Columbia and connected it with its neighboring areas (such as Ellicott City and the [[Baltimore–Washington International Airport|BWI Airport]]) until they were replaced by [[Regional Transportation Agency of Central Maryland]] (RTA) in 2014. Several [[Maryland Transit Administration]] (MTA) routes provide access to and from both Washington and Baltimore; MTA weekday commuter bus service connects Columbia to the [[Washington Metro]] system. There are no rail stations within Columbia, although the [[Dorsey, Maryland|Dorsey]] [[MARC Train]] station is served by RTA buses.
