Birmingham is also a major hub in the National Express coach network, whose headquarters are in Birmingham. The group operates services from its hub at Birmingham coach station, a new coach station on the site of the former Digbeth coach station. A temporary coach station was located in nearby Oxford Street whilst building work was undertaken. The company's flagship NXL Shuttle service operates services to London with frequent services to all major airports and cities in Britain. Many of these are cross-country services operating from north to south, for which Birmingham provides interchange facilities. Birmingham is also served by Megabus coaches that stop at Brunel Street, west of New Street station.
