Inside Europe’s trailblazing hybrid trains – BBC News
These trains are Europe’s first tri-mode trains to enter passenger service, after starting running on routes in Italy at the end of 2022.
As well as being fitted with pantograph overhead power and a standard diesel engine, they also have with a battery pack power unit and can be switched between modes.

Much of western Europe is under the most extreme red heat alerts – meaning there’s a potential risk to life.
France, Spain and Italy have been hardest hit by the heatwave so far.
But why is it so hot? What can you do to stay safe? And is El Nino to blame?
We answer some of your most asked questions about the heatwave sweeping Europe with our climate and health correspondents.
We’re also joined by our teams in Paris, Madrid and the south of France.

Tens of thousands of organisations have been caught out by a computer virus called WannaCry. The malicious software locks data away and demands a payment of up to $300 (£230) a time before it will restore scrambled files. In the UK, many hospitals fell victim and some health organisations diverted ambulances and cancelled non-essential services as they sought to contain and clean up the infection. Infections in more than 99 nations are being reported by security firms. It appears that the hardest hit are Russia and Spain.

A year ago, artificial intelligence was being sold as something close to science fiction — a technology that could transform society, cure disease, even reshape the global economy.
Today, the tone is changing. The companies leading the revolution are racing to the stock market — chasing billions in investment — while quietly confronting a much harder reality: AI is expensive, unpredictable, and far from profitable.
At the same time, some of the very people building this technology are warning we may be going too fast — even calling for a global pause.
And beyond Silicon Valley, a different story is emerging: growing public anxiety, political backlash, and the rise of what some are calling anti-AI populism.
So is AI entering its most pivotal moment yet — caught between financial pressure, technological risk, and political resistance?
AI Decoded Presenter Christian Fraser is joined by Financial Times AI Editor Madhumita Murgia, Thematic Strategist at Deutsche Bank Research Adrian Cox and Richard Coffin, Host of popular investing podcast ‘ The Plain Bagel’.

To all the people shitting on my country, 80% of Italy’s railways are electrified. And expansions are planned. Don’t act as though we only use diesel trains. It may suck for everything else, but if there’s one things Italy does fairly well, it has to be railway transport.
Do villages in the middle of nowhere, whose railway lines are yet to be electrified, deserve to have the same death traps from the 70s? I don’t think so. This is the alternative Italy is providing them with.
Just shut up if you don’t know how things work here.

It's good news because we can reduce the pollution. But we need more efficient train in future so research more and develop efficient battery for the tarin or make hydrogen energy used train both are environment friendly and we believe that the future. Looking to our country India 90 % of train are converted to electric and the 10 % are diesel. So in future we want environment friendly train and reduce the diesel train.

What on earth do you mean by "the direction of power for trains is towards that of battery power?"
it absolutely is not. overhead lines are, in pretty much every regard, a far better system that is rather trivial to implement given that trains run on rails.

@twubbles29
December 28, 2023 at 3:52 pm
Nice to see that it's not just in the US that rail operators are cheap as fuck and refuse to electrify all of their lines, forcing the construction of expensive yet sub-par multi-mode engines like this. Battery locomotives are so bad they are basically a scam.
@matthewbaynham6286
December 28, 2023 at 3:52 pm
There was a video on the YouTube channel Fully Charged a few years ago about battery electric trains, and back then there were already a couple of routes that had been converted to battery electric replacing the diesel engines for batteries without any problems.
@dykam

Over here there's duo-mode buses, as in a pantograph and battery packs. The former charge the latter while in the area with overhead wires. Other than the core network they're flexible in their routing.

Rail is the future if the government puts back into operation a lot of the lines they shutdown in the countryside . Without the restart of many of the non main lines there wilol be no change of going all electric for cars .

Trains have operating life/timeframe of 20+ years. Hybrids are not the way to go! There are multiple options by now for battery trains e.g. by Siemens and Stadler, also hydrogen options e.g. from Alstom. There are several projects now in Germany, where rail tracks will be equipped with pantographs only in stations. Inbetween battery range is enough to cover ranges of up to 200km. Diesel hybrid is a vehicle to continue selling the fossil tech.
@grolfe3210
December 28, 2023 at 3:52 pm
This seems to miss a few tricks. It would seem ideal to use the train stopping to regenerate the batteries, but this was not mentioned.
It is really so difficult to electrify all rail lines?
Given the efficiency of a train over other transport the diesel option is really not bad.

GWR received the first train (tri-mode) in the UK able to run on overhead and third-rail electric lines, as well as under its own diesel power, which was scheduled to be introduced on services between Reading and Gatwick in early 2021. They never got into service for a variety of reasons, including being too heavy for steep inclines.

Electric pantograph trains just work, especially in the UK. Hybrid or hydrogen isn’t needed for trains here imo

Successful investing is hard work because it means disciplining your mind to do the opposite of human nature. Buying during a panic, selling during euphoria, and holding on when you are bored and just craving a little action. Investing is 5% intellect and 95% temperament.

The UK might as well benefit from having new hybrid trains to replace the aging diesel trains that does need replacing including in Southwest England, Wales, North of England and Scotland. And to make our railways lot more greener to reduce Co2 emissions and to cut down on greenhouse emissions that is causing climate change.
@LudvigIndestrucable
December 28, 2023 at 3:52 pm
Slightly misleading I places. All diesel trains already are electric trains, the diesel runs generators to run electric motors. Essentially, till now they were all 'self charging' hybrids, this is just giving them a bigger battery and a plug-in option.

Rail operations group and GBRF in the uk are currently taking delivery of tri mode locomotives, for freight use. The class 93 and class 99s can run on 25kv ,diesel or 600hp batteries.

It might be a step in the right direction, but at the same time we also have Hydrogen powered trains available for two manufacturers who can completely remove the diesel a d can otherwise reach same distances between tank stops. So I am not sure why Hitachi is going in that direction?

I wonder why battery trains aren't quite there yet? It takes a lot less energy per kg to sustain the inertia of a train with steel wheels on steel rails than it does to sustain the inertia of a rubber tyred vehicle on an asphalt road. Maybe the initial power surge needed to get the train rolling? But the predictability of trains in combination with regenerative breaking should help with these moments of high energy use?
