The Detroit and Toledo Shore Line Railroad is a historic railroad that operated in northwestern Ohio and southeastern Michigan. The Pleasant Bay Railway was incorporated in Michigan in March 1898 and purchased the Toledo and Ottawa Beach Railway, an Ohio company incorporated in January 1898, in March 1899. The resulting company was renamed the Detroit and Toledo Shore Line Railroad one month later. It operated a multi-track mainline connecting Detroit, Michigan and Toledo, Ohio, serving several large industries. The main line between the two cities opened in 1903. The Grand Trunk Western Railway (GTW) and the Toledo, St. Louis and Western Railroad (the "Clover Leaf") co-owned the railroad from 1902-1923. The TStL&W ownership was transferred to its successor the New York, Chicago and St. Louis Railroad (the "Nickel Plate Road") in 1923 and then to the Norfolk and Western Railway (N&W) in 1964. The GTW purchased the N&W's interest in the DTS in 1981. At that time the DTS was dissolved and merged into the GTW. Today, a mostly single track section with limited double track and passing sidings of the former mainline continues as the CN/GTW Shore Line Subdivision. History The D&TSL operated of line between Toledo, Ohio, and Detroit, Michigan, a bridge route connecting the Motor City with the rail gateway of Toledo. Prior to the 1960s mergers resulting in Penn Central Transportation and the Norfolk and Western Railway, the link between these two cities was vitally important to the independent railroads in the area, particularly the GTW and the Nickel Plate. In 1960 it reported 243 million net ton-miles of revenue freight. The D&TSL was originally incorporated as the Toledo & Ottawa Beach Railway in Ohio and the Pleasant Bay Railway in Michigan. In March 1899 the two companies conveyed all their property to a new company incorporated under the Michigan law as the Detroit & Toledo Shore Line. The intent was to construct the railroad as a high speed interurban connecting link between the Lake Shore Electric at Toledo and interurban lines in Michigan. Immediately following the purchase of the right-of-way, they began the actual grading of the road and construction of the Ottawa River bridge just north of Toledo. From April to December 1901 the road was built from Toledo to Trenton, with trolley wires in place from Monroe to Trenton. Electric cars were tested a few times as far north as Rockwood. The line
