Thousands of people pass through Huddersfield Railway Station every day - but less than a handful will know that just below their feet is a labyrinth of tiny rooms, passageways - and even a disused subway.
The Grade I Listed station was built by two rival companies, Huddersfield and Manchester Railway and Canal Company, and Lancashire and Yorkshire Railway Company.
The foundation stone was laid by Lord Lieutenant Josh Fitzwilliam on October 9, 1846, and a public holiday was declared with church bells ringing all day.
The first train arrived in Huddersfield on August 2, 1847, and the station was finally completed in 1850.
Originally the Head of Steam and Kings Head pubs were ticket offices for the two train companies, and beneath the platforms were railway offices, coal rooms a first class lounge and a lamp room.
Today the rooms are mainly disused and lie in darkness, full of dust and dirt.
But they also lead to a disused subway, which is visible from platform 1 - gaps in the tunnel ceiling can be seen covered by mesh grills between platform 1 and 2.
English Heritage has named it one of their favourite stations, with one of the reasons being that it is “fronted by a magnificent classical portico.”
