Gulfport in the early 1930s. The Port Richmond–Tower Hill viaduct, the nation's largest grade-crossing-elimination project, was completed on February 25, 1937. The viaduct, more than a mile long, spanned eight grade crossings on the SIRT's North Shore Branch and was the final part of a $6 million grade-crossing-elimination project on the island which eliminated thirty-four crossings on its north and south shores. Freight and World War II traffic helped pay some of the SIRT's accumulated debt, and the line was briefly profitable in the 1940s. All East Coast military-hospital trains were handled by the SIRT during the war, and some trains stopped at Staten Island's Arlington station to transfer wounded soldiers to a large military hospital. The need to transport war materiel, POW trains and troops made the stretch of the Baltimore & New York Railway between Cranford Junction and Arthur Kill extremely busy. The B&O also operated special trains for important officials, such as Winston Churchill. On June 25, 1946, a fire destroyed the St. George Terminal; three people were killed, twenty-two were injured and damage totaled $22 million. The fire destroyed the ferry terminal, the four slips used for service to Manhattan and the SIRT terminal. Normal service was not restored until July 13, 1946, and a request for bids to build a temporary terminal was issued on August 21 of that year. On February 10, 1948, a replacement terminal was promised by Mayor William O'Dwyer. The new $23 million terminal opened on June 8, 1951, with ferry, bus and rail service in one building; portions of the new terminal were phased into service earlier. Ridership decreased from 12.3 million in 1947 to 4.4 million in 1949 as passengers switched from the rail line to city-operated buses due to a bus-fare reduction. In September 1948, about half of weekday trains were cut, night trains after 1:29 a.m. were cancelled, and thirty percent of the company's employees were laid off. After backlash, service was slightly increased. On September 22, the Interstate Commerce Commission allowed the SIRT to abandon the ferry it had operated for 88 years between Tottenville and Perth Amboy, New Jersey, and the ferry operation was transferred to Sunrise Ferries of Elizabeth, New Jersey on October 16. SIRT discontinued passenger service on the North Shore Branch and the South Beach Branch at midnight on March 31, 1953, due to competition from city-operated buses; the South Beach Branch
