Class 80x Differences

[whhistle]

Not really too sure about the differences between the 80x class of trains.

The 800s are OHLE trains, some slight differences within the Class (8003xx being bi-mode).
The 801s are OHLE trains. But why 801 - why not just more 800 class trains?
The 803s are build as bi-mode.

800s are bi-mode. 800/0 are 5 car, 800/3 are 9 car (both GWR), someone else will tell you what the East Coast ones are.
801s are electric only
802s are bi-mode. 802/0 are 5 car, 802/1 are 9 car (both GWR). To all intents and purposes the same as 800s but a different finance/lease arrangement. They also have larger brake resistors!

801s still have a limp-home single diesel powerpack.

pdeaves has explained it. Would be worth making it clear though that the Class 803 does not exist, some have gotten this mixed up with the 800/3s, which is now the designation for the former GWR Class 801s.

I've seen references to the TPE 5 car units being 802/2, so the Hull Trains units might be the same, or 802/3s. But haven't people also referred to Hull units as 803s as well?

Sometimes people seem to assume that the same stock has to have a different '4th digit' if used by another TOC, I seem to remember people presumed here that the GWR 387s would have their own distinct number range, but it didn't actually happen as it turned out...

I believe the 802s also have larger fuel tanks and should have the full 938bhp engine outut available across the speed range rather than up to about 30 mph.

Originally the 800s and 802s also differed in how much of their tractive effort was limited by the on board computer in order to make maintenance of the 800s easier - hence why they had a different class number. This has since been removed (at least on the GWR units, possibly on the VTEC units as well) to compensate for the reduction in GWML electrification.

Some publications seem to imply that the 800s engines are uprated from 750 to 938hp but only produce the higher figure up to 30 mph, hence why they outpace an HST to about 30 mph, then get overtaken by 60.
