Its use as a major passenger station was short lived. It was inconveniently located on the eastern edge of Birmingham city centre, and the station's facilities soon became overwhelmed by the growing traffic. Following the merging of the L&B and Grand Junction railways into the London and North Western Railway (LNWR) in 1846, work started on the new and more conveniently located 'Grand Central' station, which would become known as Birmingham New Street half a mile to the west. shared with the Midland Railway, New Street was completed in 1854. Most passenger services were diverted to the new station the same year.
