First Group order AT300 for East Coast open access operation

[Bletchleyite]

I'm not sure it massively matters now we have moved away from having a range for DMU, a range for EMU etc. Most notably it does look like all D-trains will be Class 230 regardless of what generates the juice.

I don’t think you can actually say that until every other likely variant is actually built. You would expect “diesel-electric with battery” to be 2xx, but what if they happen to build a “third rail with battery” as people keep hypothesising for the IOW?

But only for hotel power; they cannot provide traction power to move the train.

If Hitachi are promoting a version of the Class 385 that can operate for 60 miles on batteries to Scotrail, why would it be so difficult for Hitachi to sell First Group a version of the AT300 that can operate for a similar distance?

Given the modular approach to train manufacture, surely the engine space versus battery space will be near identical on both units?

 

[Japan0913]

The battery attached to the AT-300 has only power to move to a safe place at low speed if it stops on the tunnel or the iron bridge.

Battery powered railcar DMU alternative is not.

This train...
Class801 rather than "Class 395-Javelin" similar to.

I don't see anything in that link that confirms or refutes the ability to use the batteries for even emergency propulsion.

You misunderstand, I know they can sell a variant which can get its traction power from batteries, I'm not disputing that. Simply that the train being procured by First for their East Coast Trains open-access operation does not that I'm aware have the ability to use its batteries to move.

UK High Speed 1 (HS1) EMUs
Saft is providing scheduled servicing of its batteries on board Hitachi ’s fleet of Class 395 EMUs operating on the UK ’s High Speed 1 (HS1) line between London and the Channel Tunnel.
Hitachi demands high reliability from all the systems and components on board its high-speed trains to ensure a predictable and consistent service for passengers.
From its depot in Ashford, Kent, Hitachi is overseeing the planned maintenance of its fleet of 29 Class 395 trains, which have been in operation since 2009.
Each Class 395 EMU is fitted with three sets of Saft MRX batteries, which provide the power for traction and auxiliary systems in neutral sections on the electrified rail service as well as backup power. To ensure that they remain in optimum condition, the batteries are overhauled by Saft every five years.
Conclusion
Rail manufacturers and operators are naturally looking for the best return on investment for their onboard equipment. But as part of this calculation, it is important to consider the total cost of ownership of a battery is much higher than the initial purchase cost.
What is more, the choice of battery technology should be made having considered the key reliability and performance requirements of the application. There is no single battery type that is appropriate for ALL applications, and choosing the wrong battery can have potentially disastrous results in the case of failure.
Where reliability and life cycle costs are key, Ni-Cd batteries offer considerable advantages to the rail industry compared with lead-acid batteries.
Refurbishment services keep Hitachi ’s Class 395 batteries in perfect conditions

That's the 395 though.

But still, in Hitachi, but it has not been reported in the realization of a high-speed vehicle.

I'm sorry?

Not sure what this means?

At Hitachi, for now, there is no announcement of the commercialization of high-speed power storage vehicles.

So Hitachi are not planning to develop battery traction for high-speed trains any further at the moment? Is that what you mean?

Hitachi would have planned. ,
However. I do not know the fact that it has been announced.

 

[Nym]

So these versions of the Super Express Trains might even have enough battery power to keep the lights on for more than 15 mins without the auxiliaries tripping out when a Prime Mover isn't available?

 

[Japan0913]

that might just be because Hitachi seem to love the 395, go on there website and its mostly dedicated to the 395

They are quite different.

 

[Bletchleyite]

Both certainly look much more attractive than the 800, just as a 222 looks more like it means business than a 220/221 despite being basically the same thing.

Modern Railways May edition page 37 refers.

The ECML AT300s do not have the get you home single diesel generator set, and do not have battery powered traction either (as some have speculated about).

“Batteries will provide standby power only, with no traction option.” As per the vast majority of trains then...

Exactly what I was saying up thread!

Yes, I thought some third party confirmation might support you...

Thanks, I got my information from another source, but I still can't remember where!

View attachment 62581 They are quite different.

They look different to the Class 800/801/802's don't they? Any chance it will be an 803?

They look similar to the 395's IMO.

803 might be for the new trains that EMT have ordered as it will be a variant of the AT300.

Could well be, but these new trains could also be a new classification as they are different to the 800/801/802's.
