IETs

[Class465lover]

What situations/ circumstances are the engines used on the IETs? And would they be used for long distances or only like short moves?

Thanks

The IET's (GWR's Hitachi AT-300s) use their engines for quite a lot of distance, on some routes (such as Paddington - Penzanze) they will be on diesel for about half if not more of their journey.

e.g. on 1A94 1518 Penzance to London Paddington, the diesel engines are used for 251 miles (and 74 chains) with the remaining 53 miles (and 1 chain) being on electric.

South Wales services are on diesel west of Cardiff. Also diesel on diversions such as via Gloucester and Newbury.

Depends on the class - Classes 800 and 802 (both used by LNER and GWR), and 805 (Avanti), 810 (EMR) will also use the engines as normal power for running on non-electric track, However the Class 801 (LNER) is officially and EMU and only has a small engine, which is used for the 'hotel' power when required and in an emergency I think can be used to get the train to a better place to stop (i.e., a station platform) but at restricted speed and with limited range. Lumo's 803s and Avanti's 807s won't have any additional generator when they come in, AIUI.

Since they mentioned IETs that's just GWR's 800 and 802.
The others run by different names (or none at all).

801 sets run on their Diesel engine off unwired depots - which is fun for us - as well as being used in emergency situations to get a train moving. This can include OHLE failures for instance.

Starting a journey on one engine wouldn't be done in passenger service - unless in a mixed formation of an 800+801.

There isn't a speed limit when doing this as I've often seen reported. Train acceleration is very, very low though and in passenger service some auxiliary services don't actually work as power is prioritised for traction.

800/802 will run on diesel whenever there is no wiring or of there is OHLE issues as an alternative to coasting.

They're all the same fundamental design of train and all a result of the IEP, so to me they're all IETs.

The 801's engine is not small, it's the same size as other IET engines. It's just there's fewer of them.

I agree, I know someone who calls them all “Azumas”.

IETs should in my view be the overall class family name, as it describes what in theory it is. Azuma actually makes me feel ill , and completely inappropriate, after all they serve Scotland for example which is in no way "east". Cringey, I hate it. IET reminds me a little of HST!

Most of the parts of Scotland that LNER run to are in the east

But are actually (longitude/latitude wise) west of the likes of Exeter and Plymouth! Azuma is a vile name!

The overall family name is the Hitatchi A Train, or AT300 depending on which once you take. Although that designation includes the 395s which to me aren't IETs so I know what you mean.

IET is a brand name just as much as Azuma is.

They are IEP trains.

 

[pokemonsuper9]

They are IEP trains.

This debate again
The IEPs are only the 800 and 801, with the rest being independent (although the product was clearly proven) by the IEP.

IEP = Intercity Express Programme

I didn't say otherwise?

ah yes, just a misunderstanding, sorry about that
