CrossCountry removed the tilting equipment from its Class 221s to improve reliability and lower cost of maintenance.

[10] The Class 222 Meridian DEMUs are broadly similar to the original Voyager units, but feature a number of reliability improvements and different internal layout.

The Class 222 was built in the light of experience gained with the 220 and 221 units; in particular, many more components were installed under the floor so as to increase space for passengers.

In 2010 Bombardier proposed the conversion of several Voyager multiple units into hybrid electric and diesel vehicles capable of taking power from an overhead pantograph (electro-diesels EDMUs).

[30] In December 2011 a proposal to electrify 30-35 sets for the CrossCountry franchise, referred to as "eVoyager", was considered by the Department for Transport.
