Where HSTs Still Scream. Kind of.
I find it mildly amusing that companies like UKRL have made a living from the Grandfather Rights which mean old locomotives don't have to meet the same emissions regulations as brand new models. Since the 66 was killed off by IIIB regs, spot hire has had a field day as the fleets of larger operators have been stretched thin. There's only really DRS who have really gone for it in terms of getting compliant locos in their 68s and 88s (which AFAIK are the only dual or diesel-power IIIB compliant locomotives available for the UK market at present) - the rest are treading water waiting for more affordable models powerful enough to replace the 66s to become available.

I don't like to bring politics into discussions, but there's no question that EU Emissions regulations have, ironically, made the railfreight industry in the UK less environmentally friendly thanks to our restrictive loading gauge forcing perfectly good designs out of production. Nobody is competing to make IIIB compliant models specifically for the UK market, and as a result there's a lack of options for operators.

It's great for spotters like us seeing so many 56s, 37s, 47s and the like still earning their keep long after we expected them to go to the cutter's torch, but let's not pretend the state of the UK railfreight and spot-hire industry isn't anything short of farcical. We've even seen a Deltic and, more recently, a Hoover drafted into short-term mainline work in the recent past based purely on a lack of other suitable motive power on the network. As fun as it is to see Thunderer every time I pull into Leicester, it's slightly absurd that it is even necessary to consider using a 50-year old locomotive which was withdrawn and preserved 25 years ago on revenue-earning services.

There appears to be plenty of work for occasional / infrequent haulage with relatively low overall mileage (e.g. stock moves for delivery / refurb / scrap) hence the impact of using old stock is that big and also it would be hard to justify new stock to replace it at current prices.

The Claytons had to be the worst, full power and everything around disapeared in black fumes, made a steam engine look green

Getting back on topic about rail diesel pollution, an Eminox catalytic converter is being fitted as a trial to a SWR Class 159.The aim is to reduce NOx (nitrous oxide) emissions by over 80 per cent and CO (carbon monoxide) and hydrocarbons by over 90 per cent from current levels. If successful, these could be fitted to hundreds of DMUs as well as buses and lorries.

Whilst in Manilla they have thought of something altogether different to combat harmful pollution fumes...paint:

Those are amazing numbers. I had wondered if there had been any plans to retrofit older DMUs as buses (albeit much more recent one) in recent years have had equipment fitted to reduce their emissions

Turbos don't look very green with lots of fumes visible and a nasty diesel smell as they depart

I'm not sure about the 88's but the 68's are IIIa not IIIb, there's been a lot of discussion about the viability of making a 68 that is IIIb compliant due to the difficulty in fitting the additional exhaust treatment within the UK loading gauge.
