IETs into passenger service from 16 Oct 2017 and subsequent performance issues

[whole diary]

HST^▸ (High Speed Train) on the 07.30 Paddington - Penzance & rtn today.

All services to and from the westcountry (beyond Exeter) that were IET^▸ (Intercity Express Train) last week are HST today. And possibly for the rest of the week too.

There's an issue with fuelling at Laira. Apparently the IETs don't like the taste of the liquid refreshment they're getting in Devon.

The computers are saying the fuel is contaminated.

Beyond parody.

Still, we've had the wrong kind of snow, rain, leaves, sunshine etc, so why not the wrong kind of fuel too?

Perhaps its pirated fuel illicitly imported from the land of the pixies.

Oh Come on ! Perhaps it's time we cut them a bit of nutty slack .....

The old MTU^▸ (Motor Traction Unit) engines inside the HSTs^▸ (High Speed Train) obviously aren't as fussy as to what they drink. Again, computer says NO!

I am missing the bleedin' obvious - we are going up Standard Class !

Are you sure you are going up IET^▸ (Intercity Express Train)?  Could those be HST^▸ (High Speed Train) seats?

That is a possibility. The train in question is the 0805 (Su) from Cardiff.
We normally travel First (if reasonable Advance tickets are available) but decided to go up to London Standard on this occasion (via Melksham !). The two coaches (high speed services) on the reservations were both "D" - which led me off in the wrong direction, assuming both journeys were First !

Just to say that these seating plans are available to download as PDFs from the GWR^▸ (Great Western Railway) website at these links below:

0730 Padd - Penzance back to 2x5 today,

All a bit random....

The 0730 downs forms the 1400 up from Penzance. It therefore doesn’t require a visit to Laira for fuel

It’s a well known problem, GWR^▸ (Great Western Railway) have had issues with it before, MTU^▸ (Motor Traction Unit) have highlighted it on the powercars, but they have the advantage of have a very large coalescer in the engine room, absolutely no room to fit that on any unit with an underslung engine.  It has caused engine shutdowns on other fleets in GWR.

Why would you knowingly fuel a vehicle with contaminated fuel??

Welcome to the forum, Incider ... I think you know a lot more about this than most of us.   

I do wonder "how contaminated is contaminated?".  With cheese, I will eat it even with mould and it will do me no harm. But with chicken, if it looks or smells even the slightest bit off, it's a "no".  As I'm reading you, diesel fuel is more like chicken than cheese??

I can only assume it would be because Laira don’t want the trains on depot, and I assume that based on the fact that the IETs^▸ (Intercity Express Train) off Laira never departed on time and the situation with the fuel is taking a considerably amount of time to resolve.

Diesel fuel or heavy oil can have any number of problems,mostly I see the Ingres of water to the fuel systems ,this is usually due to poor storage at filling stations,where the underground storage tanks become contaminated ,however in sustained periods of hot weather diesel can actually sweat causing condensation to occur in the tank,this then leads to fungus growing in the tank ,and to the filtration system becoming blocked.

Water mainly, but with an above acceptable level of the diesel bug in it.  Any modern common rail diesel system will have its high pressure pump knackered by too many contaminants, especially water, the tolerances are so tight and it needs the right quality diesel to lubricate the pump.
