I have cribbed most of this from the Dept of Transport webpage.
Network Rail (NR) is proposing to close the railway station at Bordesley, Birmingham, on or after 4 June 2029.
NR has developed plans to increase the capacity and connectivity of the Midlands Regional Rail network by providing more services into Birmingham’s Moor Street and Snow Hill stations. This means 2 new elevated connecting tracks (chords) are required to connect the lines on the existing Bordesley viaduct from Birmingham’s Snow Hill and Moor Street stations to the Camp Hill line. The junction for the chords will be located in the space Bordesley station occupies. To construct the new chords, Bordesley station must be closed and removed.
The document below provides a lot of detail and explanation:
