They are the same seats!  Nothing more to say.  Undecided

Ah the carpet is therefore softer than the seat fabric on the Azuma (Brand name for Class 80x trains on LNER) trains too.

  Great Western, for whatever reason, stopped using class 180 (Adelante) some time back.

   I think I would prefer them to what we have now.

Only 14 Class 180s were in service so I haven’t had the chance to ride on them that much.

Based on a handful of journeys on FGW (First Great Western) and one on Hull Trains I wasn’t that impressed.

Oh and their buffet counters were taken out of service too.

Horrendously expensive to run, horrendously expensive to maintain and totally unreliable, GWR (Great Western Railway) spent an absolute fortune having a dedicated team and techs at Paddington to try and get them to see the days service out.....  The amount of staff working on them at Old Oak was inordinately large compared with other fleets.

They had issues that were never rectified, they had a hydrodynamic brake that was turned off because it made them overheat, the issues with that were never resolved.

The seats in F were nice from memory, much nicer than the Fainsa seats on the IET (Intercity Express Train).

The interiors were indeed much more attractive than the IETs (Intercity Express Train).

But my abiding memory is about reliability. Here we are at Moreton, and the driver is trying to isolate something under my coach. And yes, that is the Owner's Handbook on the ground beside him.

All this talk of polen filters makes me wonder ? Polen is not normally a problem for an internal combustion engine be it petrol or diesel powered,however it can cause havoc in an air conditioning unit by blocking the filter medium. So are our new wonderful trains being fed air conditioning into the engines? or is it that the cooling system radiator,along with any charge cooler / intercoolers are being restricted by debris etc,or have the been fitted with a very fine grade air filter element?.

I just assumed that pollen is like dust only sticky - so it coats heat exchanger fins, reducing heat flow, and needs to be unstuck to be removed. This turns out to be true, or somewhat true. Pollen stickiness is quite variable, as it functions to stick pollen to insect pollinators but isn't much help for wind-blown pollens. I would have thought the latter make up any big clouds of the stuff a train will tun across (or into), but apparently even this is a little bit sticky.

But a quick trawl for cleaning products or machinery targetted at this problem for aircon units (for example) comes up with not a lot, so evidently it's dealt with as part of normal cleaning. Maybe if you have a cooler unit that's particularly compact, thus hard to get in and clean the surfaces of (and we know why that was a serious design issue for the IEP (Intercity Express Program / Project.)), cleaning will always be a bit marginal. So if this is one of a number of fouling types that call for extra cleaning methods to be applied, it would not be a surprise - and you'd expect any initial problems to be soluble.

I'm understanding that the issue is [now] somewhat wider than purely pollen - air filters in general, and not helped by all the extra diesel mileage being run compared to what was originally expected.  No wires beyond Cocklebury Lane, no wired down Filton Bank, no live wires yet into Wales. Add to that the uprating of the maximum power of the diesels from 560 to 700 horsepower (or whatever the figures are) and you have them running harder and longer than they were planned / designed for.

At a guess I would say, and I have seen this all too often, someone somewhere was being PENNY WISE, POUND FOOLISH.

5 replacement BUS STOP flags at my local bus stop in 7 years, a £20,000 bus stop with shelter for ONE bus a day, Monday to Friday on College Days Only and yet the Council refuse to connect other shelters to the electricity supply even though the shelters were supplied as flatpaks including electrical boxes and lights, assembled and erected as such and in many cases next to a street lighting column too.

Several services that would have been operated by IETs (Intercity Express Train) are cancelled today, many others are part cancelled, and on the Bedwyn services IETs are replaced by turbos.
Presumably this means more units are available for servicing and rectification by hitachi. With this splendid opportunity to catch up on works attention, may we look forward to greatly improved IET availability during the coming week.

Sounds like a bonus for Hitachi. No compensation for lack of availability today, and perhaps improved availability in the coming week.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

1C76 overshot Newton Abbot today and lead to a 26 minute delay. Apparently a brake fault according to somebody on facebook however they ran it down to Penzance and then back up to Paddington so for some reason I highly doubt it

Glastonbury is over.
The weather is only moderately warm, certainly no heatwave.
Hitachi had a bonus on Sunday with a chance to catch up on maintenance.

Still well over a dozen half length trains today after a similar number yesterday. It looks as though this is the new normal.

Voyager mark two, but with worse seats, and no shop/buffet.

The two remaining sets to enter traffic can’t come soon enough!  The diesel only list had shrunk to just three yesterday mind you.
