2025 is being celebrated as the 200th anniversary of the birth of the passenger railway. A bit premature, although there was a one-off excursion on the Stockton and Darlington railway, with passengers traveling on coal wagons, the regular passenger service from 1825-1830 used horse-drawn coaches.
In 1830, the Liverpool Manchester railway opened, the first connecting 2 cities and the first scheduled passenger service.
