Kilmarnock & Troon Railwa

The Kilmarnock and Troon Railway (K&TR) was an early railway line in Ayrshire, Scotland. It was constructed to bring coal from pits around Kilmarnock to coastal shipping at Troon Harbour, and passengers were carried. It opened in 1812, and was the first railway in Scotland to obtain an authorising act of Parliament; it would soon also become the first railway in Scotland to use a steam locomotive; the first to carry passengers; and the River Irvine bridge, Laigh Milton Viaduct, is the earliest railway viaduct in Scotland. It was a plateway, using L-shaped iron plates as rails, to carry wagons with flangeless wheels. In 1841, when more modern railways had developed throughout the West of Scotland, the line was converted from a plateway to a railway and realigned in places. The line became part of the Glasgow and South Western Railway system. Much of the original route is part of the present-day Kilmarnock to Barassie railway line, although the extremities of the original line have been lost.
