The Nova 1 fleet had originally been ordered by TPE's predecessor as part of plans to bolster route capacity by 80%; having contracted with Hitachi Rail Europe for the latter to supply 19 five-car bi-mode trainsets. According to Robin Davis, TPE's Head of New Trains, a major rationale behind the Nova 1 fleet was its bi-mode capability, noting that electrification ambitions often had much uncertainty, while a bi-mode fleet eliminated the operational risk to such uncertainty. Davis also noted that, in the event of largescale electrification being funded and implemented, the Class 802s could have some of their engines removed to reduce roughly 15% of their weight and thus raise their efficiency. Furthermore, Leo Goodwin, TPE's managing director, has observed that while the Class 802s will have an initial maximum speed of 125 mph, they have the capability of being modified for operating at 140 mph if infrastructure upgrades were to permit such speeds at a future date.
