began with the closure of the booking offices in the old station, after the last tickets were issued for the 5:25 a.m. London train and the new booking offices were opened in time to issue tickets for the 6:25 a.m. Erewash Valley train. No attempt was made to exclude the public from the building and many took the opportunity to view the new station buildings. The Evening News commented on the public's admiration of the style and elegance of the station approaches and booking hall; it went on to describe the day's events. 20th century The station became the property of the London, Midland and Scottish Railway, under the railway grouping of 1923. On Sunday 2 July 1939, the station was targeted by the Irish Republican Army in an attack on eight stations in the Midlands under their S-Plan; the others being Leicester, Derby, Birmingham, Stoke, Coventry, Leamington Spa and Stafford. A bomb was left in a suitcase and exploded at 6:30 a.m. The glass roof of the cloak room and enquiry office was blown away. The station was nationalised in 1948, under the Transport Act 1947, becoming part of British Railways. Following the privatisation of the railways in the 1990s, ownership was transferred to Railtrack and subsequently to Network Rail. For many years, the Midland Railway suffered the indignity of its rival, the Great Central Railway, crossing above the station on a bowstring girder bridge. This bridge became redundant in 1973 and was finally dismantled in the early 1980s. The alignment was later used for a new tramway bridge. Station Street tram stop With the opening of the Nottingham Express Transit (NET) in March 2004, Nottingham station became the southern terminus of the new tram line. The actual tram stop was located on Station Street, directly north of Nottingham railway station and partially over the Nottingham Canal. It was constructed on a separate right-of-way, built on top of part of the old Great Central Main Line viaduct that used to lead northwards to the separate Nottingham Victoria railway station. North of the former stop, the tram route diverged from the old railway route to join an on-street section through the centre of Nottingham. To the south, the route ended at the end of the viaduct, where a since demolished bridge used to carry the Great Central line over the station. In 2012, work started to extend Nottingham Express Transit
