The A-Line is a planned rapid transit line running along James Street in downtown and Upper James Street on the escarpment in Hamilton, Ontario. It is part of Hamilton's proposed BLAST network, involving four other rapid transit corridors. It is identified by Metrolinx in its regional transportation plan The Big Move as a project to be completed by 2023.
The line is envisioned to run between West Harbour GO Station and John C. Munro Hamilton International Airport. On May 26, 2015, the Government of Ontario announced the B-Line would be constructed between McMaster University and Queenston Circle, as well as a segment of the A-Line to provide a direct connection to West Harbour GO Station. The capital costs for the project will be $1 billion, funded entirely by the province. Procurement is expected to begin in 2017, and line construction is expected to begin in 2019.

Usage examples of "a-line".
The microfabric did not need tent poles or stakes-all you had to do was double-crease the lines of the fabric you wanted rigid, and those folds would stay taut in a hurricane, but setting a microtent up was a bit of an art, and the other two watched while I expanded the fabric, creased the edges into an A-line with a dome center tall enough to stand in, and folded the suddenly rigid edges into the sand to stake it.
