Capital Trail, Delacarlia Tunnel under MacArthur Blvd.

Built 1910 as tunnel for railroad IMG_3390.jpgIMG_3387.jpgIMG_3392.jpgIMG_3385.jpgIMG_3386.jpgIMG_3393.jpg moving coal between Maryland and Georgetown.

Notice one of the alcoves for someone walking on the tracks to duck into and avoid oncoming train.

The  buttresses flanking the round arched opening and the detailed cornice, along with emphatic barrel vault,  are appropriately architectonic for the powerful railroad engine and its load.
