Philadelphia introduces 25 new electric buses, claims largest zero-emissions fleet on U.S. East Coast
Quote
...between the 25 new e-buses and 38 trackless trolleys, SEPTA now has the largest zero-emission bus fleet on the East Coast. Some may not be willing to count those trolleys, but even a bus fleet with 25 electric buses ranks at or near the top of East Count cities in that regard.

That title may not last long, however. New York City only has 10 electric buses in its fleet as of April, but the country’s largest city has said it will add 65 more electric buses before the end of the year, and 500 more within the next five years.

The main topic of the concept is modular architecture, which enables use of the platform 24/7 with various modules - for example as a bus during the day and as a truck during night.
   •   8m long
   •   162 kWh battery pack under the floor, cylindrical cells
   •   range of 245 km (152 miles)
   •   the bus version can take 55 passengers (20 seats)
   •   weight of 8 ton

Electric, Autonomous And Modular Scania NXT Unveiled
Quote
Scania NXT hints the future of electric buses and trucks beyond 2030

Scania presents at the UITP Global Public Transport Summit in Stockholm (10-12 June) all-new all-electric concept - the Scania NXT, which is envisioned as fully autonomous vehicle for 2030 and beyond.

"Welcome to the NXT future! Scania’s new battery electric self-driving urban concept vehicle is designed with the flexibility to shift from ferrying commuters to and from work in mornings and evenings, delivering goods during the day and collecting refuse at night.

In a bold display of innovation, Scania’s engineers have taken the company’s DNA – the modular system – to the next level in developing a concept vehicle that can change shape for varying urban assignments." ...

German railways to stop using glyphosate on tracks
https://phys.org/news/2019-06-german-railways-glyphosate-tracks.html

German state-owned rail operator Deutsche Bahn is to stop using glyphosate (RoundUp) on its tracks and is looking for substitutes to replace the controversial weedkiller, one of its board members said in an interview Friday.

The rail operator is Germany's largest user of glyphosate and buys nearly 65 tonnes of the herbicide per year to stop weeds from propagating on its tracks.

"We want to set up a research project to find effective ways to operate our 33,000 kilometres (20,500 miles) of network without glyphosate to be environmentally friendly," infrastructure chief Ronald Pofalla told the weekly business magazine WirtschaftsWoche.

The World Health Organization classifies glyphosate as "probably carcinogenic".

Just look at the price. I don't travel 1st Class, but in school, m son has to present a trip to any city, showing costs, lodging and possible activities. So I found this. It is for 4 peoples.

It is a trip via Paris. Via Brussels is cheaper (somewhere between 1500 EUR and 2000 EUR) because only half of the way is done with a high speed train and it takes about 1 hour more. The problem via Brussels is that the train from Luxembourg used to be (don't know how it is now) often late, so you were not sure that you got the Eurostar in Brussels (I did it 9/11/2001, and when I came out in Brussels, I wondered why the guy at the desk told me insane stories about planes crashing in the Twin Towers, I was in the tunnel when it happened).

We need to return to steam engines.  The waste steam could be used to cook the weeds.

Quite frustrating, I just booked a trip by train to London in September. Plane would have been more or less half the price. From the traveling time, it's not a big difference (around 7h by train, little bit more than 1h by plane, but airports are more difficult to reach and you need to be much earlier at the airport than at the train station. I hope there is WIFI in the Eurostar otherwise the kids will not be too happy.

Interesting how different jurisdictions approach weeds on rail tracks.
There is a railway that goes from Alaska through B.C. in the Yukon.
It decided to spray various poisons on its rights of way to kill weeds.
Alaska simply said it was not allowed. Period.
The Yukon had a big environmental assessment that concluded it was a bad idea.
B.C. had no rules, no permits needed.

"We want to set up a research project to find effective ways to operate our 33,000 kilometres (20,500 miles) of network without glyphosate to be environmentally friendly," infrastructure chief Ronald Pofalla told the weekly business magazine WirtschaftsWoche.

My wife's brother lives in northwestern Germany and flies all over the world for business. Recently he has been quite affected by Greta, and I used this to suggest to him to take the train rather than fly when he travels to London, which happens from time to time. He was quite receptive to the idea, and it turns out travel time is roughly the same door to door, however the train price is something like double. In order to get the same price, he has to order the train ticket 60 or 90 days in advance, which he can't do as his business is quite hectic. I guess some economist at the rail company thought this scheme up for solid financial reasons, but it's quite frustrating in the context of AGW, as last-minute plane tickets are always more competitive than the train.

I've no doubt that the above is the first solar train, but a wind powered light rail system has been running in Alberta (of all places) for a few years.


No link but I believe it carries commuters about in Edmonton.

Are you serious?

If so, don't you think you could save CO2 by not having the need to build an infrastructure to provide the train with power? Do you know there are efficiency gains by not having the need to transport power over a distance?

When every train would be solar-powered (which is obviously possible, as shown in the video), this would be a huge efficiency gain and therefore less CO2 emissions. How is this not a good thing?

Well, I ordered the tikets about 45 days in advance. Even for non business reason, a small city trip, this is quite a lot in advance. 15 days ago, the school year was not over and only the main part of the holidays was booked. The only reason why we go now to London is the Brexit. A no deal could make future travels more complicated.

EUROPE REVIVES NIGHT TRAINS — TO FIGHT CLIMATE CHANGE
https://www.ozy.com/fast-forward/europe-revives-night-trains-to-fight-climate-change/95904
Quote
Arnaud Wieclawski wanted to visit his girlfriend in Italy last year. But the Belgian faced a problem: There was no real alternative to a plane ride, which the ecologically minded Wieclawski wanted to avoid because of the carbon footprint of flying. So he turned his dilemma — a choice between love and the climate — into activism. He co-founded Back on Track Belgium, a collective arguing for the reintroduction of a transportation solution that Europe has turned its back on: night trains.

When every train would be solar-powered (which is obviously possible, as shown in the video), this would be a huge efficiency gain and therefore less CO2 emissions. How is this not a good thing?

I watched the video, some interesting points:
- The 6.5 KW of solar panels on the train is enough only to trickle charge
- The 30KW of panels on the station is what really charges the train (done twice a day to charge the batteries)
- The track is only 3km long, and its pretty flat!
- As stated in the video, the location has nearly perfect weather conditions for solar power

- The actual narrator accepts that it would make sense for most (nearly all?) operators to run a third rail and get energy from the grid.

This is like claiming we will soon be flying in planes running on solar panels because of those experimental ultra-light one man planes that have done so.

Electrical trains & trolleys have been around longer than the grid. ;)
Transporting electricity by way of 3d rail or overhead catenary is much more efficient than charging, transporting and discharging (heavy) batteries.
PV is a fair weather friend. Rather than vertically integrating railroads so they provide their own (solar) power, why not GreenWrap them by having them purchase only solar, wind or renewable power?

   Rail line in Hampshire is world's first to be powered by solar farm

Pilot scheme on Network Rail’s Wessex route could pave way for direct powering of trains


Great initiative I think. Especially effective in sunny countries.
I wonder what they'll do when it snows. Battery backup? Use the grid?

https://www.theguardian.com/business/2019/aug/22/rail-line-in-hampshire-is-worlds-first-to-be-powered-by-solar-farm


Quotes:
Leo Murray, the director of Riding Sunbeams, said future projects across the UK could be community-owned, and pay back benefits to local community funds. By the end of 2020, Riding Sunbeams hopes to build and connect the world’s first-ever full-scale community- and commuter-owned solar farm to UK railways.

Murray said the railways will be able to cut their running costs and benefit local communities while playing a part in tackling the climate crisis. “Matchmaking the UK’s biggest electricity user, the railways, with the nation’s favourite energy source, solar power, looks like the start of the perfect relationship.”


Murray added that the same model could be used across the world, particularly in sunny countries in South America, and India.

India is already home to 250 trains powered by solar panels attached directly to the roof of the train, but it plans to develop its own trackside solar farms because the weight of the panels means their trains need more energy than usual.

Indian Railways, the country’s single largest energy consumer, said last month it hoped to become the world’s first 100% “green” railway network in 10 years’ time by installing 30GW of solar generation capacity on some of its 51,000 hectares of vacant land.

New rider data shows how public transit reduces greenhouse gas and pollutant emissions

So, with that data, the researchers could quantify the emissions produced and miles traveled of the transit systems (TRAX light rail uses electricity produced outside the Wasatch Front, hence the emissions aren't in Salt Lake's air) and balance that with the miles traveled by passengers and the estimated amount of car travel avoided by riding transit.

On weekdays during rush hours, and in densely populated areas, the balance was clearly on the side of reduced emissions. "That tapers off significantly during the evening hours, on the outskirts of the city, and definitely during the weekends," Mendoza says. In those situations, the number of passengers and how far they rode transit did not offset certain criteria pollutant emissions. (Criteria pollutants are six common air pollutants that the EPA sets standards for through the Clean Air Act.)

For transit to improve its regional reduction in emissions, particularly PM2.5 and NOx, the following strategies, alone or in combination, could be employed: more daily riders per trip, more clean-fuel buses and train cars and/or fewer low-ridership trips

...

The current study looks at the bus and train fleet as they are now, with some UTA buses around 20 years old and FrontRunner trains whose engines are rated a Tier 0+ on a 0-4 scale of how clean a locomotive's emissions are (Tier 4 is the cleanest; UTA is scheduled to receive funds programmed through the Metropolitan Planning Organizations to upgrade FrontRunner locomotives to Tier 2+). So, Mendoza and his colleagues envisioned the future.

"What if we upgrade all these buses, some of them from 1996 or so?" Mendoza says. "They emit a significantly larger amount than the newer buses, which are 2013 and newer."

What if, they asked, UTA upgraded their buses to only 2010 models and newer, fueled by either natural gas or clean diesel? And what if the FrontRunner engines were upgraded to Tier 3?

Emissions of some pollutants would drop by 50%, and some by up to 75%, they found.

Worthwhile study.  But any “upgrades” to busses should include electric vehicles, over natgas or ‘clean diesel.’

Deutsche Bahn sees big windfall from climate change package
https://www.todayonline.com/world/deutsche-bahn-sees-big-windfall-climate-change-package
Quote
Germany's Deutsche Bahn [DBN.UL] expects the government's 50 billion euro climate change package to generate the railway company's biggest growth spurt in its 180-year history, the state-owned firm's boss said on Sunday.

In a telephone press conference, Richard Lutz said the measures announced on Friday, including a cut in value-added tax (VAT) on train tickets, would give it an additional 20 billion euros in revenue by 2030.

Although the package, in response to growing public concern about the impact of climate change, disappointed climate activists, individual measures such as surcharges on domestic flights and the VAT cut are expected to have an impact on the companies concerned.

Weeellll... there are other opinions or discussins on the matter

https://www.truthorfiction.com/railwidth/

In Britain there were several rail gauges in use so it would be interesting to have some more rigorous information why this specific gauge was selected.

I intended to add something about british gauges but my browser has a hiccup so perhaps later if more discussion is warranted...

Weeellll... there are other opinions or discussins on the matter

In Britain there were several rail gauges in use so it would be interesting to have some more rigorous information why this specific gauge was selected.
