Rail-Punk: the LNYA

My entry for MotF 43: Rail-Punk: when the golden age of Railways is turned Up to Eleven.

-----------------------------------
The era of the Big 4 has turned into the Big 6.

In Britain and Ireland the old 4 remain, having expanded and changed over time.
Southern Railway has expanded further south, becoming the LPER.
LMS and the LNER went through a series of mergers and splits, eventually re-forming as the INWR and a new form of LMS with characteristics of both companies.
The big gain for the British rail companies has been in America. There, the Great American Railway (GAR) dominates the United States east of the Mississippi, whilst the CDR has lines running from Quebec to Vancouver.
And joining the two continents is the LNYA, the London, New York and Atlantic Railway. Originally expanding from the Great Western, the LNYA covers South-west England, Wales, southern Ireland and the Atlantic coast of America from New York to Newfoundland.

Of course, facilitating in this amazing expansion of the railways were breakthroughs in tunnel technology. There are currently no less than three tunnels across the English Channel as part of the LPER, five across the Irish Sea, three part of the INWR and two part of the LNYA, and of course the two Atlantic Tunnels, the backbone of the LNYA.

This map is a poster from the LNYA, showing the main lines of the Big 6. Obviously the geography isn't accurate across the Atlantic, consider it more like the tube map.
