December timetable change in 2022, five more units were transferred. Midlands In 1997, Central Trains inherited twenty units from Regional Railways for use mainly on medium-distance services such as: Birmingham to Nottingham via Derby or Leicester Birmingham to Hereford Birmingham to Shrewsbury and the Cambrian Line Nottingham to Skegness or Lincoln In an attempt at fleet standardisation, preparations were made during 2003 to exchange all 20 Class 156s for an equal number of ScotRail Class 158s, with 156402 partially repainted in ScotRail colours in readiness when overhauled at Wabtec, Doncaster. The transfer did not proceed after the Scottish Government refused to sanction the move, and the rest of the fleet were reliveried into Central Trains' colours between 2003 and 2005. Nine units were transferred to One during early 2005, in exchange for a similar number of Class 150s. At the end of the Central Trains franchise, the remaining 11 units were transferred to East Midlands Trains, who repainted the fleet during 2008 and then carried out a refurbishment program from autumn 2010 onwards. The refurbishment, carried out at Neville Hill depot, included interior refurbishment work, improvements to driving cabs and installation of CCTV. These trains are now used on slower medium-distance services such as Nottingham/Derby to Matlock, Nottingham to Skegness, Leicester to Lincoln and Nottingham to Worksop. In May 2011, four additional units were transferred from Northern Rail to allow Nottingham to Liverpool services to be strengthened. Beginning in late 2019, the nine class 156s transferred to Greater Anglia in 2005, passed to East Midlands Railway. Because they had a different public address and passenger information system to EMR's existing Class 156 fleet, they were renumbered into the 156/9 subclass. In December 2022, four units were sent for storage at Barrow Hill, with East Midlands Railway stating that they will be moved to Ely Papworth sidings at a later date.
