馬里蘭區域通勤鐵路
The Ivy City rail yard saw new activity beginning in March 2012 when MARC Train, the Maryland regional commuter train line, began construction one three tracks at the rail yard at a cost of a $21.3 million ($million in dollars). The tracks were to store MARC trains during midday layovers, reducing the time needed to get trains to Union Station during morning and afternoon rush hours. Amtrak still maintained some offices at the Ivy City rail yard as of 2013.
