Umm, were cows not happily belching methane before humans even started herding them ?


I think, back in those days Simon, cow numbers were a very, very tiny fraction of what they are today and therefore their emissions were not an issue...

Cows and the like are a very inefficient ways of producing food for humans.. If the land they graze was used to grow plant-based food instead it would be much, much more efficient...

A good start to reducing bovine methane emissions would be to cut meat production and encourage people to eat far more plant-derived food...

It is not necessary to eat meat every day or even every week - as us who are largely vegetarians can attest :)

After all, it used to be a luxury and reserved for special occasions only...


This film underlines that Jim, in particular from the 29 minute mark but the whole film is linked to the same theme, not just meat but agriculture and fishing plus all the things that affect this and are affected by it.

It is distributed under the creative commons licence and free for anyone to watch.
It is so good that I bought the DVD to see it on a big screen in decent quality.
It does come over as being a bit preachy but the subject is a serious and engaging one despite this.

Keep your hands off my steak Jim, I don't really fancy pretend meat made in a plastics factory. :-D


Don't worry Gibbo, no way... Even I enjoy a bit of beef very occasionally and I'm pretty much a full-time veggie! And anyway, I believe in free choice in everything. A dictator I am not!

We, as humans, MUST eat some animal-based food to ensure a healthy balanced intake of nutrients but we don't need much... Eggs, of which I eat loads, give us almost all of what we need and top it off with a little bit of cheese every now and again and all is good :)

And us true veggies don't look for meat substitutes ;) For me at least, it's the real thing or nothing! No funny sausages or bacon for me :lol:

And cows will never be extinct or even endangered... The biggest vegetarian community in the world in India hold them sacred - that alone will ensure they survive in good numbers :)

Simon, most interesting on the "Impossible Burger"... It will satisfy many people but it's not for me for reasons already stated :)

It's a brilliant film, so much I used to regularly broadcast it freely to the internet back in 2012.
If you only enjoy the videography alone, it's worth it!

So whats happening at BMW

Well on the plus side they have announced their aim to have a range of 12 Battery Electric Vehicles in their showrooms by 2025.
Speaking at BMW’s annual financial results conference, the German brand’s CEO Harald Kruger said: “With the fifth generation of eDrive, our vehicles will be able to drive 550 to 700 kilometres (340-435 miles) on electric power, depending on the model. We will achieve this in the BMW i4.”
On the minus side

German prosecutors have raided the headquarters of BMW as part of an investigation into the suspected use of emissions cheating software.

The BBC has a short piece on the VW car 'graveyards' in the US that store around 350 000 cars they've had to buy back.. The video shows just one of their 37 sites :shock:

As someone who gets a train into Glasgow Central station every day, I'm amazed at the amount of pollution that the Diesel-Electric trains are still allowed to belch out! [-X It really is horrible. Fortunately the line I am on was electrified about a year ago.

Are there no Euro regulations for smoke from Diesel busses and locomotives like there are for cars ??! :roll:


Yes, emissions regulations apply in the same way (new build, not backward applicable) and IIRC, use the same 'Euro' class for emissions, albeit the implementation timescales have differed.
Different timescales is for a number of good reasons, e.g. design timescales for rail vehicles are much longer, they have to comply with a whole host of extra safety regulations and getting products and design changes through those as well isn't an overnight activity, the volumes are significantly lower so the supply chain is not going to be as responsive and things tend to be made in batches and stockpiled for future use rather than being able to switch/change as needed etc.
Rail vehicles and the components in them have a much, much harder life than automotive and therefore they need to have a longer life-cycle and different design.
Automotive engines have been tried in rail vehicles in the past, with appalling results.
e.g. a diesel railcar might typically cover 80-100,000 miles a year and have a 35 year life (loco's can be far higher on both counts). The engine duty cycle is generally idle for a reasonable period of time, then straight to flat out load for long periods of time, not held at part throttle for the majority of its operation. Space to mount equipment is at a premium and cooling isn't necessarily efficient (you can't front mount a radiator, for a start!) and access to maintain and service isn't easy either. This drives the need for a different product.
Typical overhaul cycles for a railcar engine might be 250,000 miles for a top end overhaul, 500,000 miles for full overhaul - so you can see that over the life of a rail vehicle, the engine will actually be used 7 times over (which in itself is far more efficient/environmentally friendly than an automotive application) and in fact, the engine will probably be used even longer than that, as a common engine gets shared round the whole national pool (that's how it worked in BR days, less so these days tending only to be shared across the same leasing company at best).
Particularly with locomotives, the 'bespoke' nature of the engines and the sheer value of them, can drive faults that would write an engine off in automotive world to still be repaired (massive gaping holes in the side of blocks where they've put a leg out of bed etc.). I expect in that particular regard, it's similar to other industries such as shipping (although that has nothing like the same level of safety regulation that causes extra constraints I mentioned earlier).

FWIW, the newest diesel trains being procured for Greater Anglia are (IIRC) Euro IIIb compliant, which means they have all sorts of gubbins you'd find on more modern road vehicles, including using AdBlue...

Yeah and what's due to happen to them? All they need to do is modify the software and they'd be emissions compliant - far more environmentally friendly option than scrapping them and building a new car?!

I think they'll quietly find their way back onto the market in States that are less fussy about the environment than CA or exported out to the Mddle/Far East.

Lots about railway diesels...


Iain, as one who is keenly interested in all railway I found that most interesting and enjoyable. Thanks :D

There can't be many trains that are E111 compliant - so why are they allowed in LEZ's or, at least, without penalty? I mean those responsible for these Zones & their policing - sorry, management - aren't interested in reasonableness or fairness (or, it seems logic or even reality).

Yes I don't believe there there are any that are Euro IIIb compliant yet (but the vast majority of loco's are IIIa compliant).
But even so, as for fairness or logic, that's very simple... Fine, ban the trains.
Then count up how many extra cars/vans/lorries have to come in instead of just one train, which, even though they may be compliant with more modern emissions standards, will actually pollute more (not to mention add massively to the congestion).
Just sticking with freight, as an example a typical diesel loco can haul up to 1800 tons, using 1x 132Litre engine.
Typical 44 ton HGV might have a 13 Litre engine. Scale that up to equivalent haulage and you would have 40x 13 Litre engines (520Litres combined).
Now that's not in the least bit scientific :lol: (and I'm not an expert in those engines at all so may well have got some numbers wrong) and doesn't equate directly to emissions etc but it's a pretty good simple exercise to show how much more efficient rail is at moving big loads.
And then just picture those extra 40 lorries on the streets...

I have just had a little chuckle, thinking of a Hermes locomotive outside my door delivering my small parcel fro easydiagnostics. :)

Personally, I like seeing black exhaust from a Diesel engine, especially when they are being thrashed.... very immature I know, but growing up around farm machinery where the engines are lucky to have silencers let alone any form of emissions control probably has something to do with it :rofl2:

Obviously, the chemist in me knows that the exhaust contains plenty of nasty chemicals that should best be avoided. That’s why I support DPF's on cars as pedestrians are usually present at the same level as the exhaust fumes, but I don't see the point on trains or especially on tractors!

Kind of an ironic statement given the thumbnail of your video showing a cloud of diesel fumes hovering around the platform where people will be standing ? :lol:

As someone who caught a Diesel powered train into Glasgow Central for a couple of years - which has a canopy over the end of lines where all the trains terminate, I can assure you that people are in fact "at the same level as the exhaust fumes", and I can still smell the fumes now a couple of years later! :twisted:

Waiting at the platform for a train while trains on adjacent lines leave the platform belching clouds of stinky diesel fumes was horrid. :roll:

The sooner Diesel trains are gone the better as far as I'm concerned!
