Question: Name the railroad in Canada which is a short line railway operating between Portland, Maine on the Atlantic Ocean and Montreal in Quebec which had Coaticook station on its west side completed in 1853?

<P0-S0>  The first station, which was on the west side of the tracks, was completed in 1853 by the St. Lawrence and Atlantic Railroad. <P0-S1>  The current building was constructed on the east side of the tracks in 1904 by the Grand Trunk Railway. <P0-S2>  The two storey wooden frame building has a single storey conical roofed southerly end and a small extension on the north end. <P0-S3> Coaticook station is a historic building in the small town of Coaticook, Quebec, Canada, close to the border with the United States. <P0-S4>  One of the façades includes a two-story bay window topped by a gable-pediment. <P0-S5>  The old station is located in a semi-wooded area in a residential area of the town. <SEP> <P1-S0> The Oregon, Washington and Idaho Railroad built a 72.03 mi rail line along the right (north) bank of the Snake River between Riparia, Washington and Lewiston, Idaho. <P1-S1>  The company was incorporated in Oregon on August 8, 1903, and began operating its completed line on July 7, 1908 as an operating subsidiary of the Union Pacific Railroad (UP), which also controlled the Oregon Railroad and Navigation Company (OR&N) through Riparia. <P1-S2>  A portion of the preliminary work had been done by the Snake River Valley Railroad, which built a completed line along the Snake River below Riparia. <P1-S3>  Beginning on December 3, 1909, the Camas Prairie Railroad, a joint subsidiary of the OR&N and Northern Pacific Railway (NP), began operating the Oregon, Washington and Idaho Railroad (OW&I) as part of a line between Riparia and Grangeville, Idaho, including segments owned by the NP and subdidiary Clearwater Short Line Railway. <P1-S4>  On December 23, 1910, the property of the OW&I was conveyed to new UP subsidiary Oregon–Washington Railroad and Navigation Company, successor to the OR&N, but the Camas Prairie Railroad continued to operate it as agent. <SEP> <P2-S0> The St. Lawrence and Atlantic Railroad (reporting mark SLR) , known as St-Laurent et Atlantique Quebec (reporting mark SLQ) in Canada, is a short line railway operating between Portland, Maine, on the Atlantic Ocean and Montreal, Quebec, on the St. Lawrence River. <P2-S1>  It crosses the Canada–US border at Norton, Vermont, and is owned by short line operator Genesee and Wyoming. <SEP> <P3-S0> The Rockland Branch is a railroad from Brunswick, Maine to Rockland, Maine. <P3-S1>  A charter was granted in 1849 to build a railway from the Portland and Kennebec Railroad on the west side of the Kennebec River to Rockland. <P3-S2>  Construction through the rocky headlands of the Atlantic coast proved more expensive than anticipated. <P3-S3>  The Knox and Lincoln Railroad commenced service to Rockland in 1871 using a ferry to cross the Kennebec River between Bath and Woolwich. <P3-S4>  The Knox and Lincoln was leased by Maine Central Railroad in 1891, and became Maine Central's Rockland Branch in 1901. <P3-S5>  Maine Central purchased the Samoset destination hotel in nearby Glen Cove (a part of neighbouring Rockport) in 1912, and offered direct passenger service for summer visitors from the large eastern cities. <P3-S6>  Carlton bridge was completed in 1927 to carry the railroad and U.S. Route 1 over the Kennebec River. <P3-S7>  Maine Central sold the Samoset hotel in 1941, and the last Maine Central passenger train to Rockland was on 4 April 1959. <P3-S8>  The State of Maine purchased the branch in 1987 to prevent abandonment. <P3-S9>  The line has subsequently been operated by the Maine Coast Railroad, the Maine Eastern Railroad, and, beginning in 2016, the Central Maine and Quebec Railway.
