To increase station safety, the Maryland Department of Transportation (MDOT) Maryland Transit Administration (MTA) has begun installing safety bollards – short, sturdy vertical posts that serve as physical barriers – at all of the agency’s 14 Metro Subway stations from Owings Mills to Johns Hopkins.
The bright yellow bollards create a barrier to prevent passengers from stepping off the platform between railcars. The bollards are positioned in front of the gaps between railcars (as shown in the photo above) and prevent riders, especially those with visual impairment, from mistaking the gap for a train door opening.
