Euston railway station
In 1837 Euston railway station opened, the first railway station connecting London with the industrial heartlands of the West Midlands and Lancashire. Railways were banned by a Parliamentary commission from operating in London itself, and thus the station was built on what was then the northern boundary of the built-up area. Other main line termini soon followed at Paddington (1838), Bishopsgate (1840), Fenchurch Street (1841), King's Cross (1852) and St Pancras (1868). All were built outside the built-up area, making them inconvenient to reach.
