Class 800/802 difference

[Blillpers]

I've skimmed through the 200+ pages in the Class 800 discussion, but been unable to find an answear to the rather simple question: What is the difference between a class 800 and a class 802, other than the formations and number of coaches per unit?

As I understand it the 802 were supposed to have up-rated engines and larger fuel tanks, but the 800 fleet has now also recived these upgrades?

Different interiors? Anything else?

The 802s are substantially cheaper, being financed through the conventional ROSCO leasing route, rather than a DfT PFI type deal.

802s have bigger brake resistors on the roof. That's about it really from the technical point of view. It's mostly to do with the procurement process. 800s are supplied by Agility to the DfT, 802s are supplied to GWR by Eversholt.

Is this change owed to longer distances away from the wires?

Is anyone specifying less awful seats?

So I'm told. In electric mode, the primary braking method is regenerative. 800s have a brake rheostat but it's only there for very brief use when regen isn't available (e.g., in a neutral section). The larger brake resistors on 802s allow rheostatic braking as the primary brake in diesel mode (which reduces the wear on the friction brake components) as they will be spending less time under the wires.

Well they should have had a Buffet and perhaps less drab interior but unfortunately it looks as though they have been given the same interior as the 800's and of course no Buffet.

At the risk of restarting a 50-page argument, I believe the Engine Management Systems on 802s will allow higher acceleration on diesel than that on 800s.
They also have a different maintenance regime with a greater proportion of planned usage on diesel.
802s from the same batch are also destined for Hull Trains and TPE.
Some of the 802s will be assembled by Hitachi in Italy (Pistoia) rather than in Japan or Newton Aycliffe, but they all have the same spec.
It's a First Group contract with Hitachi for 802, rather than a DfT one for 800/801.
Eversholt is financing the GWR sets, Angel is financing the HT/TPE sets.

As far as I'm aware, no 802s are being built in Newton Aycliffe, only Kasado & Pistoia. Newton Aycliffe is full up with the IEP and Class 385 orders. Everything else seems correct though.

I'm sure thats true of the GWR stuff but TPE own press release stated that most of TPE ones will be built at Newton Aycliffe

I think we should rename this thread to Class 802 so that the discussion is preserved and avoids repeating it (I'm sure someone else will ask the same question again)

They are not the first pic of the 802s.
They’re the first of the TPEX ones though .

It was my understanding that the 802s have larger fuel tanks and higher engine power.

It was my understanding that the 802s have larger fuel tanks and higher engine power.

The fuel tanks will be identical to the 800 sets as both are now being fitted with the larger 1550L tanks. The engines power will be the same, 700kw, but hopefully will be available at more of the speed range than the 800 sets have apparently been set up for. The acceleration rate on diesel should also be 0.82 rather than the 0.7 on an 800.

Hitachi's press release just says the TPE units will be built at their global manufacturing sites.
They will also be maintained at Hitachi Doncaster, which is off the routes TPE says they will be working on.

*Notes on testing and manufacturing
The new fleet of Hitachi intercity trains (Class 802) were ordered by FirstGroup for TransPennine Express in 2016.
The trains will be built across Hitachi’s global manufacturing sites.
The first two trains to be built in Japan are test trains (802201 & 802202). Testing in the UK will begin in summer 2018 ahead of the trains entering passenger service in December 2019
