The local service to and from Coventry to Wolverhampton calling all stations was also changed in 2004, it was split at Birmingham New Street as Central Trains starting operating Class 321 EMUs. A later development was implemented that had trains running express from New Street to Birmingham International (with some stops at Marston Green) then all station to Coventry and services to Walsall were extended to Birmingham International calling all stations, Adderely Park station was cut down to one train per hour shortly after this.
