Great Western Railway. Designed by John Skipton Mulvany , Broadstone Station is constructed of granite in a neo-Egyptian style. With Galway projected to become the main port for transatlantic passenger traffic between Europe and North America, the Midland successfully competed with its rival the Great Southern and Western Railway to reach it first. A special fourth class was introduced by the Midland for poor migrants from the west going to Britain for work. The line, which branched out to serve Sligo, Westport, Achill and Clifden, was also used to transport huge numbers of cattle. It was about this time that the majority of the houses in the area were constructed, as dwellings for workers on the railway. Most of the worker's houses were built by the Artisan's Dwelling Company, which built many similar estates in Dublin and elsewhere, and houses of this type are now frequently described as Artisan cottages, regardless of their origin. Decline of the canal The Great Irish Famine of the mid-19th century had caused a huge wave of emigration, and the population of Ireland was reduced from about 8 million in the 1830s to around 4 million a century later. The worst hit were the rural population of the west, precisely the market of the MGWR. There was a brief period of boom in the 1870s as the flow of people from the west peaked, but as the people left, traffic in the other direction reduced markedly. As emigration gradually came to a halt, so did the canal system. The MGWR was never very interested in the canal business and in 1877 they were given permission by the government to close of the branch line and to fill in the harbour, to construct a new forecourt for the station. That removed the need for a movable pontoon bridge, and a new approach road, Western Way, was built by way of Foster Aqueduct. The harbour was no longer needed due to the construction of one larger and better situated at Spencer Dock, and was filled in to become the forecourt of Broadstone Station. The small reservoir had been made almost redundant by the construction of a new reservoir at Vartry in 1868, and served only the Jameson Whiskey distilleries at Smithfield, until they left the city in the 1970s. By the 1920s average annual tonnage on the Royal Canal had reduced to 10,000 tons. In 1924 the
