After retirement from Gatwick Express several sets were purchased by Network Rail for use as test trains or simply as brake-force runners.

In addition two coaches have been converted for departmental use with Network Rail: In 2001 eight carriages were sold to Northern Ireland Railways for further use as locomotive-hauled stock in combination with the 111 Class locomotive, and renumbered 8941 to 8948.

The NIR coaches were withdrawn on 19 January 2005, but were re-introduced in September 2006 to provide extra capacity on the Portadown to Belfast Central service, making one trip every morning.

In 2009 the locomotives and coaches were due to be converted to push-pull operation following the purchase by NIR of a DBSO last used by National Express East Anglia.

Ian Welch of the Mainline Steam Trust in New Zealand has purchased a number of ex-BR MkII cars formerly used on this service.

Three cars comprising set 488313 (TSOLH 72624 and 72625, TSOL 72172) and a further two from 488209 (TFOH 72508 and TSOH 72644) arrived in New Zealand in 2008, still bearing the Intercity livery with 'Gatwick Express' branding.

They will also receive new names as well as the new MLST MkII livery of Pearl Grey roof with Midnight Blue body and white window band.
