Liverpool and Manchester Railway
The Liverpool and Manchester Railway  was the first inter-city railway in the world. It opened on 15 September 1830 between the Lancashire cities of Liverpool and Manchester. It was also the first railway to only have locomotives driven by steam power, with no horse-drawn traffic permitted at any time; the first to be entirely double track; the first to have a true signalling system; the first to be fully timetabled; and the first to carry mail.
