Thanks for that, Tony. I'm sufficiently distant from the GCR management at the moment to be unaware of that, and as I don't subscribe to any of the preservation rags I've not picked it up from there either. I have, however, written a suitable paragraph in to my presentation for the June shindig to create what we'll call "a discussion". Importation of coal would be an absolute nonsense although I believe it's going on even now.
Let's modify our locos to run on wood pellets, then we'd be environmental and have no carbon footprint.
Zero carbon means that, in due course, our heritage diesels will have to learn to run on hydrogen as well. And (he says in less than total ignorance) how much does it cost in energy to produce usable amounts of hydrogen?
