Rolls-Royce signs deal to trial hybrid-electric train conversions

LONDON — Rolls-Royce has signed an agreement to conduct a trial conversion of diesel trains to hybrid-electric engines in Britain, in a deal which could be rolled out to hundreds of trains across the country starting in the 2020s. The British company, which is best known for making aircraft engines, said on Wednesday that its German Power Systems business had signed an agreement with Porterbrook, the UK's largest owner of passenger rolling stock. Rolls-Royce's Power Systems unit, which sells engines used on ships, yachts, trains, trucks, mining and nuclear power stations, is one of the fastest growing parts of the company, and its boss said hybrid technology is behind that. "We expect hybrid technology to grow at above the current growth rates of diesel," the CEO of Rolls-Royce Power Systems, Andreas Schell, told Reuters. The Power Systems business is expected to post low double-digit revenue growth this year and is a bright spot in a company grappling with the negative headlines and cost of fixing a problem with its Trent 1000 aero-engines. Diesel trains can be fitted with Rolls-Royce Hybrid PowerPacks to turn them into hybrid trains that can also run on battery power, reducing carbon emissions and making them cheaper to run for operators while also making them much quieter when, for example, they approach stations. From RR's press release: The MTU Hybrid PowerPack is an environmentally friendly drive system which combines the advantages of diesel and battery-powered rail traction. The version for Porterbrook incorporates an MTU diesel engine which fulfils future EU Stage V emissions regulations; plus an electric machine, which can be used either as an electric motor or generator; and an MTU EnergyPack battery system, which stores the energy recovered during braking. This enables very low-noise, emissions-free battery-only electric operation in urban areas and around stations. The hybrid initiative comes as Britain seeks to phase out diesel-only trains by 2040. Adding the powerpacks to trains allows railway networks to be partially electrified without the need for expensive overhead infrastructure. The Institution of Mechanical Engineers says that 42 percent of Britain's rail network is currently electrified, which means that the country lags behind electrification rates in other European nations. Last year the British government scrapped electrification projects in some parts of the country, saying it would look to hybrid technology trains instead.

Rolls-Royce Wraith Luminary Collection gets celestial headliner

Rolls-Royce has announced a new bespoke collection for its Wraith 2-door luxury coupe that is highlighted, literally, by a headliner full of glittering shooting stars. It's called the Wraith Luminary Collection and its production will be limited to just 55 examples. The car is like its own planetarium on wheels, thanks to a starlight headliner concocted by the folks at the Rolls-Royce Bespoke Collective in Goodwood, West Sussex. It's a handwoven configuration of 1,340 fiber-optic lights mimicking the night sky — and even the occasional shooting star — and it takes 20 hours to configure. Rolls-Royce says eight shooting stars fire at random, mostly over the front seats. Open up the suicide doors and you'll see the celestial theme continued inside the cabin. Tudor oak wood veneer, sourced from forests in the Czech Republic and chosen for its depth of color and grain structure, is back-lit by 176 LED lights that permeates through intricate perforations in the veneer that form another starlight pattern at the touch of a button. "Linked to the controls of the starlight headliner, the cabin's veneer surrounds Wraith's occupants in an ambient glow of light," the luxury marque says. Outside, the Luminary Collection comes pained in Sunburst Grey with rich Saddlery Tan-colored lines hand painted along the bonnet and side body, a color scheme inspired by "the heady shade of the golden hour's sunrays" and referencing the interior leather color scheme. It's also echoed in the center of each wheel. Cockpit seats come trimmed in the same tan leather, while rear seats feature a contrasting Anthracite leather or an available Seashell color for the leather, matched by a two-tone steering wheel. The seats get contrasting piping and stitching tying the colors together. Also new is a hand-woven stainless steel fabric, a new technique for luxury goods borrowed from industrial uses, for the center console and door panniers. Each swath is made up of strands between 0.08 and 0.19 millimeters in diameter and takes three days to produce in a clean-room environment. Finally, the collection features stainless-steel tread plates engraved with the words, "Wraith Luminary Collection — One of Fifty-Five." Prices weren't announced, befitting the brand's aura of exclusivity, but the Wraith starts at a mere $320,000.

Bloodhound hits 210 mph in test for land speed record run

It was actually 210 miles per hour, 10 mph faster than promised. The rest of the day went swimmingly, and on schedule, by the Bloodhound land speed record team. "The car ran for 20 minutes, and it did two full-power runs, with full power for 5 seconds, and 0 to 200 mph in just under 9 seconds," said Mark Chapman, Bloodhound's chief engineer. "So the exciting bits were about 18 seconds long, but people were here from dawn to dusk. The atmosphere was unbelievable." Bloodhound, which will travel at 70 mph simply on the idle of its EJ200 jet engine, had to be held back on the brakes before wing commander Andy Green floored it for 5 seconds. The jet flamed and roared on afterburner and then it was over. I might have given a little squeak; it was mightily impressive. "This is a really big engine," said Richard Noble, Bloodhound project director and former land speed record holder, "and when it runs, there's a flame and a crackle and boom, and people think, 'My goodness, that's really something.'" It was, and Green might well have thought so when he first came to apply the brakes in testing for the inaugural public run last week on the runway at RAF St Mawgan near Newquay in Cornwall. "We've had some interesting times working out how carbon brakes work, because they do take a while to warm up," said Chapman. "The cockpit footage online shows Andy's eyes looking like dinner plates when he puts his foot on the brake and nothing happens for a bit." Typically, Green took it all in his stride. He is one of just three people alive to have traveled at 600 mph on the ground (Richard Noble and Craig Breedlove are the others) and was hugely impressed with Bloodhound. "The car is absolutely fabulous," he said. "From day one, it felt right: crisp and precise, you can feel it on the road; it's super. There was only one slight surprise on the braking and that was more to do with the engine over-swing." This meant that the Rolls-Royce Eurofighter engine wouldn't shut off immediately when Green lifted from the throttle. "That delay was a real surprise to us," he said, "because all previous jet cars have had mechanical fuel-control systems where a rod closes a valve and a quarter of second later, all thrust has gone. The EJ200 engine, though, manages its own fuel supply based on what the digital throttle request is, and it takes quite a lot longer to stop.
