a rounded font, and graphics along a lower railway map-type stubbed stripe. The passenger doors are white on the yellow sides and yellow on the brushed metal sides. There is Merseyrail 'M' branding on each of the passenger doors, as well as on the cab fronts. The livery is applied as a vinyl skin. Replacement Merseyrail expected that the Class 507 and 508 units would be withdrawn around 2014 and replaced by a new EMU, but this was postponed following a refurbishment. In May 2012, Merseytravel announced that it had formally begun a project for replacement. The fleet received a refresh package including external re-livery, internal enhancements and engineering work. In January 2016, Merseytravel announced the short list of companies bidding to build new trains which will replace the Class 507 and 508 on the Merseyrail network. In December 2016, Merseytravel announced that Stadler had won the £460million contract and that the new trains would be delivered from summer 2019 with all the old trains replaced by 2021. The first unit entered service late in January 2023.
