It was the line closed last night, due to the railhead being underwater, so closed to all traffic, not just 800/802.
Would this prevent damage to the engines? Does the engine need to be running for the problems that are being experienced to occur or is it just the general soaking that would cause the problem?I stand corrected! Something like that would do just the job. Though rather than coughing up money for the entire route to be electrified or for an avoidibg route to be built I can totally see this government paying to electrify between Exeter and Newton Abbot only.
I think they increased the fuel capacity on the 802s, so the original IETs might not be able to manage the West of England diagrams. I also think I there was also some mention of the 802s having better protection against salt water due to expected running via Dawlish - taking the thread title absolutely literally does this ban only apply to the original IET units or the 802s as well?Then if the IET stock is more hardened, swap them in times of need. I'm sure that the GWML services can be run with 802s for a few days per year.
Ok, seems that is probably more plausible than a total IET ban, I happily stand corrected. However, it is a fact that in past 2 days many IETS have lost multiple engines along dawlish, including the 1703 off London which lost 5 of 6, so something needs to be done.It was the line closed last night, due to the railhead being underwater, so closed to all traffic, not just 800/802.
Intakes can be designed to avoid water ingress - think the likes of snorkels on Land Rovers. Or boats and ships!
It reads to me like someone missed a trick on the specification, as what happens there is clearly more than spray. Oops.
A train isn’t a boat or ship and snorkels on Land Rovers don’t make them immune from water ingress if they receive a huge dowsing from above or the side. They just improve wading capacity which is not the issue here.
Ian`t it in the contract that they must be able to operate through Dawlish even with high waves? If so , could be expensive for Hitachi
This will be much more disruptive than the Voyagers as the 80x make up a much bigger proportion of the service in that area. Any details on work is necessary to rectify this?
Hopefully they are working on a fix. Not the first time a train was got grounded a fixed. Look at the 91s and the wrong type of snow.
overheating HSTs, 158s disappearing from signalling systems.
I wonder why they never bothered fixing the voyagers. Surely it isn’t impossible.
Was it not the 373s that were caught out with them wrong kind of snow’?
Should’ve used VAR...So this basically isn’t true and there’s been a load of speculation and guessing about all the trouble Hitachi are going to get into. Why post something that’s a bit of a guess?
Because I clearly stated it was something I'd heard from a colleague and that I wasn't certain it was completely true . I have since held my hands up it turned out to be false , but fact remains, IETs currently are not resilient enough to cope with dawlish, whether that will change is anyone's guess.So this basically isn’t true and there’s been a load of speculation and guessing about all the trouble Hitachi are going to get into.

Hmm. Not sure that wouldn't make things worse.Should’ve used VAR...
Service was suspended for all trains briefly Tuesday due to very rough seas; and resumed when additional staff were secured to ride the trains through the affected section.
Sprinters and HSTs have lost engines while traversing the sea wall in rough conditions and being struck by waves. It’s nothing new. I’m sure Hitachi are looking at ways of improving resilience - as @northernbelle points out they are already looking at software updates to de-sensitise the engines which are cutting out for seemingly silly reasons at present.
Just going on what I've heard from a colleague could be total BS , but I know there have been multiple incidents of losing engines in past two days and 1703 off padd I believe is down to 1 of 6 engines , time will tell I suppose

what are the extra staff for?
From what I've been informed this week, it will need more than a "plug a laptop in and download some software updates" type situation. However, Hitachi are aware of the issue and will be working on it. It isn't to do with the air intakes, but seemingly isn't so much software related either.
Explain to me why it wouldn't?If you believe that this is fixable with a mere software fix, then you are probably the type of person who believes Boris Johnson will deliver on all his promises, haha.
Look at voyagers , been trying for years to fix them, and we are still none the wiser how to dawlish proof them. Why would IETs be solvable with just a software tweak?
