Public transportation

While Randallstown was at one time the planned terminus for the Baltimore Metro Subway,^[12] the line was ultimately built to nearby Owings Mills. Though no stops on the line are actually in Randallstown, the three stops in Baltimore County are all within a close drive of the Randallstown area.

Bus service in Randallstown is available on the Maryland Transit Administration's bus routes 54 and 77. There is no bus link between Randallstown and nearby Carroll County, in part due to longstanding opposition to inter-county public transit from Carroll County officials and residents.^[13]
