Vernon Avenue. A new freight station was built. As part of the project, there would be no grade along the line from White Plains to Mount Vernon. The roadbed at Hartsdale and Scarsdale would be lowered to reduce grades. In 1910, a yard dating back to the 1870s in Dover Plains was relocated to Putnam Junction in Brewster. On October 18, 1930, the Public Service Commission (PSC) listed the elimination of a grade crossing in Amenia, Benson crossing, as one of its projects to consider. The cost estimate for eliminating it was $100,000. The New York Central operated the Berkshire Hills Express and several other through trains to Pittsfield and North Adams along this route to Chatham; then the NYC's Boston & Albany mainline to Pittsfield and the B&A's North Adams branch to North Adams, into the mid-1940s, with dining service. 1950s and 1960s In 1950, the through service to North Adams was trimmed to a shuttle from Chatham to North Adams, requiring a transfer at Chatham. Passenger service between Chatham and North Adams ended in 1953. However, the Berkshire Scenic Railway now operates a 5-mile tourist train between North Adams and Adams, Mass. On September 11, 1952, the New York Central's next-to-last steam-powered train run in the New York City Metropolitan area ran on the Harlem Division, being replaced by diesel locomotives. However, the diesels began wearing out in the 1970s, leading to a decline in service. The last New York City Metropolitan area New York Central steam train left Harmon for Albany and points west on August 7, 1953, behind NYC Niagara 4-8-4 #6020, after which the entire New York Central system became dieselized east of Buffalo (and east of Cleveland, Ohio the following month). On December 20, 1956, the state opened up bids for the elimination of grade-crossings in Pleasantville. Planned for 25 years, this was expected to cost $3.857 million. The crossings to be eliminated were at Manville and Bedford Roads. The tracks were lowered for and the two roads were bridged over the railroad. The station at Pleasantville was moved. On August 12, 1960, the PSC ordered the New York Central to continue the level of service to Chatham until it determined how much service was required. The Central had wanted to cut one train each way daily, leaving only one round-trip. Starting on October 25, 1961, some trains became equipped with two-way radio communication
