I recently came across the lovely and nostalgic promotional poster from Ireland's Midland Great Western Railway shown above.  Although I live one of the areas formerly served by this grand old railroad, I didn't know much about the history thereof.  I've shared the information below for all you folks who are railway buffs, or who simply enjoy the nostalgia that comes with train travel.

The Midland Great Western Railway (MGWR) was the third largest Irish gauge (1,600 mm (5 ft 3 in)) railway company in Ireland. It was incorporated in 1845 and absorbed into the Great Southern Railway in 1924. At its peak the MGWR had a network of 538 miles (866 km), making it Ireland's third largest network after the Great Southern and Western Railway and the Great Northern Railway of Ireland.

The MGWR served part of Leinster, County Cavan in Ulster and much of Connacht. Its network was entirely within what in 1922 became the Irish Free State.

The Midland Great Western Railway Act received the Royal Assent in July 1845, authorising it to railse £1,000,000 capital and to build a railway from Dublin to Mullingar and Longford and to buy the Royal Canal. Construction of the main line began from Dublin in January 1846 and proceeded westwards in stages. It opened from Broadstone (Dublin) as far as Enfield (County Meath) in May 1847, to Hill of Down in December 1847 and to Mullingar in October 1848.

Rivalry existed between the MGWR and the GS&WR, each of which wanted to build the line to Galway. The MGWR extended its line from Mullingar and the GS&WR from its line at Portarlington. The MGWR was first, going via Athlone and reaching Galway, 126.5 miles (203.6 km) from Dublin, in August 1851. It was not until 1859 that the GS&WR got as far as Athlone. The GS&WR was obliged to operate its service over MGWR track between Athlone and Galway, paying the MGWR 65% of passenger and 55% of goods receipts. The GS&WR retained a separate station, which is now the sole operating station, as the last service to the MGWR station ran on 13 January 1985.

In 1890 the Government granted the MGWR £264,000 to build a railway to Clifden on the Atlantic coast of County Galway. It opened as far as Oughterard in January 1895 and to Clifden in July 1895. Due to its inland route it did not serve the bulk of the area's population, so the GSR closed it in 1935.

A similar branch line was built at the same time from Westport to Achill on the Atlantic coast of County Mayo. The MGW built the first section, opening it as far as Newport in February 1894 and Mallaraney in May 1894. The Board of Works built the section from Mallaraney to Achill, which opened in May 1895. The GSR closed the line in 1937.

In 1924 the Oireachtas of the Irish Free State passed the Railways Act, which that November merged the MGWR with the Great Southern and Western Railway (GS&WR), Cork, Bandon and South Coast Railway to form the Great Southern Railway. In January 1925 this was joined by the Dublin and South Eastern Railway to form the Great Southern Railways.

The MGWR painted all of its locomotives bright emerald until about 1902, when the first of the new Class A 4-4-0 express locomotives were outshopped in royal blue. This did not wear well and in 1905 the company adopted grass green. From about 1913 locos were painted gloss black until the MGWR became part of the GSR.

Passenger coaches were finished in varnish or brown paint until the blue livery was introduced in 1901. As on the locomotives this weathered badly and from 1905 the MGWR reverted to brown, which after 1910 was not so well-adorned with lining. From October 1918 coaches were painted a very dark crimson, and after 1924 the GSR adopted a similar shade.

Those of the former MGWR's main lines that are still open are owned and worked by Iarnród Éireann. Routes between Dublin and Sligo, Athlone and Galway, Athlone and Westport and the Ballina branch remain open to passenger traffic. The Meath on Track campaign is campaigning to have the Navan — Clonsilla line (not to be confused with the former GNR Navan — Drogheda line) reopened earlier than the 2015 date announced under Transport 21. The Edenderry, Clifden, Achill, Cavan, Killeshandra, Ballaghaderreen, Ballinrobe, Killala and Loughrea branches lines are all closed.

Platform 11 has proposed running some Galway — Dublin services via the MGWR station in Athlone and the disused route via Moate to Mullingar, reinstating the route of the first MGWR service via the former GS&WR line. The current Galway service runs from Dublin Heuston.

Three former MGWR stations are now hotels, two of which are called the "Station House Hotel" but are unconnected by ownership. They are the much-expanded former Clifden station in Co. Galway, Kilmessan Junction in Co. Meath and the Mullranny Park Hotel at Mulranny, Co. Mayo.

The Great Western Greenway is a greenway rail trail that uses the route of the former Westport — Achill branch line.

No MGWR locomotive has been preserved but several of its standard six-wheeled carriages exist. One stands derelict at the Station House Hotel in Clifden and another three are on the Downpatrick and County Down Railway. Another, owned by the Railway Preservation Society of Ireland, is being refurbished for public use on the Downpatrick line. The MGWR's unique saloon coach built for William Dargan is at the Ulster Folk and Transport Museum, Cultra, County Down, Northern Ireland.
