The town of Sykesville, Maryland, acquired salvageable parts to the structure and reconstructed it in 2000; it opened in November 2002 as a   Post Office and welcome/information center. The site for the tower is along Oklahoma Avenue, in front of a former Pullman sleeping car, not far from the old Sykesville train station.   A portion of the ground floor of the building is used as a place for visitors and residents to pick up brochures and information on town events and to view displays and photographs depicting local scenes. Another portion of the ground floor includes a unique contract postal business, which provides all types of mailing services to town residents, and businesses.   The top floor, where the operator once worked, is a 20-by-38 foot open area for use as a meeting space. Visitors may also use this space to get a panoramic view of the town through its 20 large windows. The second floor is also available for rental.   B&P, named for the old Baltimore & Potomac Railway, had the largest interlocking plant between Philadelphia and Washington. With 107 levers on its machine, it controlled part of the Northern Central branch, the switches into the old sleeper yard, the tracks leading to Calvert and Hilton stations, as well as main track moves between Penn Station and B&P Tunnel. Other action in its time included moves onto the Maryland & Pennsylvania Railroad directly across from the tower, and moves up the high-line behind the tower to the B&O diamond at North Avenue en route to Mount Vernon yard.   The Tower closed as an active office on July 14, 1988.   The building sat unused for a number of years, but it was in the way of construction of the Penn Station leg of Baltimore’s light-rail line. In 1995, the city of Bowie, Maryland, agreed to take the building for a park project, possibly as a boat house, but not as a tower museum since it already had one of those. B&P Tower’s top floor was dismantled (its base remained at the original site and remains there today) and its parts were stored in an unprotected area. Plans for the park project never reached fruition. When the town of Sykesville acquired the salvageable parts, it was noted that much of the rest of the original building had deteriorated too badly for use. An architect was hired to design the building patterned after the original and incorporating as much of the original material as possible.
