I wonder if TPE will ever run 10-car trains like this on their routes!
Not in normal service, there won't be enough units for that, even if platform lengths were accommodating enough.I wonder if TPE will ever run 10-car trains like this on their routes!

No as they don't tilt.Doesn't it make sense for VTWC to replace some of their voyagers with these?

Not that I am aware of for the class 802. The franchise agreement permits an option to be exercised to purchase up to 23 additional 5, 6 or 8-car class 397 EMUs, rather than extension of any existing units: Presumably taking up the full number of additional units would be dependent on the approval of Transpennine North electrification in full.From memory, there is an option for them to be extended to 6 cars though isn't there?
I think it was a phrase first used by Ian Warmsley in Modern Railways when describing the various safety organisations as he put it "trying to out safe each other" to try achieve intimate safety presumably at infinite cost.Is it actually possible for you to make a post that doesn't feature the phrase 'Safety Taliban'?
Presumably the TPE 80x will like the LNER ones be blocked from entering passenger service until the cable ladder issue is resolved to the satisfaction of the safety Taliban. I wonder what they think of thisView attachment 57717
The QSK19 is a Straight 8 IIRC.what about the type of engine as well...? the 185s have 19 litre straight sixes and the 802s will have 21 litre V12s
So it is, thanks!Straight 6.
It is starting to look likely that TPE will beat LNER to the "first 80x in passenger service on the ECML" milestone... Which is odd, considering that it's partly signalling compatibility problems on the northern ECML that's apparently holding back the LNER introduction.
TPE still plan to have their ECML service (including the extension to Edinburgh) running with 802s by the end of this year, but LNER don't seem to be planning to have their 800/801 fleet running north of York until next year. Which of them manages to run a passenger service with the new trains first is certainly going to be close...
Technically they're the same rating, it's the software that extracts the full power rather than being 'electronically de-rated'.
The 800s have had a mod to make it the same now, haven't they?
Interesting. I hadn't realised 800s had less power than a 185 although hp per ton would be a better measure than hp/m as the 185s are heavy trains. Are the 800s lighter?engine power per metre length wise, 5-car 800/802s are about 66% of the power of 185s (22hp/m vs. 33), 9-car versions about 62%. There will also be differences to consider with comparative efficiency between the hydraulic transmission on 185s and the electric transmission on 800/802s, as well as the fact that above 30-40mph, the power output of 800s is further reduced by 20%.
If you trust the numbers on Wikipedia, a 5 car 800 is about 8 tonne lighter per car than a 185. This works out as only 14% lighter.Interesting.

I always thought it a pity Hitachi couldn't find a suitable straight horizontal engine rather than a 21litre VEE which would have avoided the step up onto the raised floor.

I am sure it is, but the question is when the fix will be in place. TPE needs to get its units into service quickly to deal with overcrowding. If their Hitachis can run on diesel for now then that is a blessing, except for the emissions obviously but that at least will be temporary. It would also be an unplanned benefit of opting for bi-modes. They will have passed the resilience test from the off!I thought it was just the fuel tanks being replaced with long range 802 tanks due to the reduction in electrification? Getting the full output from the engines would probably cancel that out, but as it's a software thing I don't suppose it would be difficult to do.
As far as I know the signal interference problem is being overcome, it's not like it hasn't affected things in the past and it's always been overcome before.
