interior modifications during the 1990s. After the introduction of high back seats during refurbishment in 2004/2005 this was reduced to 192 with space for cyclists and disabled people improved. The Class 507 (and 508) replaced LMS-designed Class 502 EMUs on the Northern Line and Class 503 EMUs on the Wirral Line. Current operations From new, all Class 507 units have worked the Merseyrail network. Sets have been used interchangeably between the Northern Line and the Wirral Line since 1997, so work the following: Northern Line –Hunts Cross line Ormskirk line Kirkby line Wirral Line New Brighton line West Kirby line Chester line Ellesmere Port line Fleet details Livery details 507s have appeared in various colours over their lifetimes. BR Blue and Grey (1978–1994): the initial livery lasted until well into their careers on Merseyside. The units also carried the MPTE 69 logo and Merseyrail branding on the driver's side of the outer ends of the driving vehicles. Merseyrail Original (1993–2001; repaints 2001–2004): yellow with white around the windows and black and grey stripes, exclusive to Merseyside EMUs. Merseyrail Revised (1999–2004): a lighter yellow, and no black stripe. Merseyrail Refurbished (2003–2015): silver, with vertical curved yellow stripes receding from the cab ends. The passenger doors were all yellow, introduced as a safety measure by Merseyrail. 'M' branding on the front ends and on the sides, and a Merseyrail vinyl.

Merseyrail Capital of Culture (2008–2009): based around the Merseyrail Refurbished livery, with overlain graphics. Photographs depicted focus on some of the weird and wonderful innovations from Liverpool, such as the SuperLambBanana. The colourful liveries met with mixed reactions from travellers.

Merseyrail Hope University (October 2012 –): pale background with text and graphics, advertising Liverpool Hope University. The passenger doors are all yellow, as a safety measure which was introduced, previously, by Merseyrail. The livery is applied as a vinyl skin. This livery is unique to unit number 507002. Merseyrail Good Communications (January 2014 –): six different designs, half with a yellow background, and half with a brushed metal background, applied with each set having one yellow side and one brushed metal side. Both sides have lifestyle text, in
