Central Trains had a major shakeup between 2004–05 to prepare them for the eventual break up of the franchise. The first part of this was done in 2001 when the Birmingham New Street to Chester & Mid Wales and Cambrian Coast Line was transferred into what is now the Wales & Borders franchise. In 2004 services from Leamington Spa to Birmingham Snow Hill & Stratford upon Avon were transferred into Chiltern Railways, but the company maintained a peak hours services to and from Leamington Spa. The service between Birmingham and Stourbridge was increased to every 10 minutes and this in turn increased the Kidderminster service, as a part of the new Stourbridge line timetable all remaining Birmingham New Street trains were diverted into Birmingham Snow Hill. Liverpool Lime Street to Stansted Airport split at New Street to form two services due to problems with delays. Previously Central Trains ran services from Birmingham New Street to Nottingham via Leicester as well as Derby, this service was split, the Leicester to Nottingham service was merged with the hourly Ivanhoe Line service to Loughbourgh and was extended past Nottingham all stations to Lincoln.
