In November 2012, unit 91114 had a second pantograph added as a pilot project operated jointly by Eversholt Rail Group, East Coast, ESG, Wabtec Rail and Brecknell Willis. The new design uses the same mounting positions as a conventional pantograph but pairs two pantograph arms in an opposing configuration. If there is an ADD (Automatic Dropping Device) activation or the pantograph becomes detached, the train can keep going, so the system provides redundancy in the event of a pantograph/OLE failure. This has since been removed, but the extended lower roof is still visible.
