Leif A. Dormsjo, MDOT's acting deputy secretary, said his department and CSX officials are considering four parcels of land currently owned by CSX in South Baltimore. The possible sites are in the areas of Locust Point, Curtis Bay, Mount Clair and Mount Winans, he said.
Stephanie Rawlings-Blake asked the company in April to consider placing its intermodal facility in the city.
Dormsjo said the company is exploring building a smaller facility in Baltimore than what it had planned for locations outside the city, in Howard, Anne Arundel and Prince George's County.
If a Baltimore location isn't selected, the company and the state would return to evaluating options outside Baltimore, Dormsjo said.
The truck-to-rail center is needed to allow CSX to bypass the narrow, century-old Howard Street tunnel beneath Baltimore. The tunnel is too low for transport of shipping containers stacked two high.
A CSX spokesman said the company was continuing to "evaluate all options to develop an intermodal facility."
