In July 2012, it was announced by Network Rail that the Midland Main Line (MML) would be electrified north of Bedford, allowing the diesel trains currently used on the route by to be replaced with new electric trains.[9][10] However, electrification was 'paused' by Network Rail in June 2015,[11] and then cancelled in July 2017 by then-Secretary of State for Transport, Chris Grayling, who made the decision to use bi-mode trains on the MML instead.[12]
In August 2019, East Midlands Railway placed a £400 million order for 33 five-car bi-mode units, to replace its Class 180 and 222 fleets on the MML.[13][14][15][12][note 1] The purchase is being funded by Rock Rail East Midlands.[12] It was originally planned that the new trains would enter service before December 2022;[17][18][19] following multiple extensions,[7][20] the fleet is planned to enter service in early 2025 as of March 2024.[1]
In October 2020, following a public competition,[21] EMR announced they would be branded as Aurora.[22]

The Class 810 is a modification of the Class 802 units Hitachi have delivered to a number of British train operators.[23] The major change is a 2-metre (6 ft 7 in) reduction in the length of each vehicle, which is required in order to allow paired (ten-car) Class 810 trains to use London St Pancras station.[4] Some of the length reduction has been achieved by reprofiling the front end of the train and shortening the nosecone.[3]
Compared to Class 802 units, the 810s will also be fitted with an additional diesel power pack—for a total of four—and each engine will be uprated from 700 to 735 kW (939 to 986 hp). Both of these changes are intended to satisfy the franchise requirement that the new trains equal or exceed the performance of the current Class 222 units.[3] The power packs will be installed under the first, second, fourth, and fifth vehicles, while the third (centre) vehicle will carry the high-voltage transformer. Traction motors will be fitted to the bogies of the second and fourth vehicles.[4]

In response to customer feedback regarding seating comfort on earlier Class 80x units, both first- and standard-class seats on the Class 810 will be of a unique design that is intended to offer enhanced comfort. They will be based on the existing FISA Lean design, but of an altered appearance. EMR were working closely with Derby-based design company DGDESIGN on the design of the new interiors.[24] It is claimed that the seats will have wider cushions, more-sculpted headrests, softer and deeper armrests, additional privacy screening, and be upholstered in a wool-rich moquette that is intended to be easier to keep clean. Every passenger will have access to power sockets and USB charging points, at-seat coat hooks, and storage space under each seat.[25][26]
