Fun fact, on GWR there’s no actual difference between 800s and 802s beyond the fuel tanks being a bit smaller on the 800s. All of the engines on the 800s were remapped to match the 900hp per engine 802 power output for fleet versatility purposes (they were always intended to have the same engine so it was an easy job).Kudos to Hitachi for designing a versatile train around all the disasters the DfT threw at them. They were originally intended to be light in weight and to run up and down fully electrified Great Western and East Coast Mainlines as the 801. Then GWML electrication got cut back massively so they needed the bi-mode 800 with Diesel engines to be fired up after Newbury unless they were heading down the South Wales mainline. Then they didn't work on the steep gradients into Devon and Cornwall and had to be able to sustain lashings of salt water at Dawlish, so the 802 had to be created. Now they're expected to carry the back bone of commuter services in some parts of the country as well.
The 800s on LNER however maintain their original 750hp output as all their units spend the majority of their time on electric.
