there was a demonstrator day in april where we witnessed the aht kit on this shunter. there was...ed in the product in the first place. what we're looking at is the kind of gap in the next five to ten years, between 100% diesel and zero emissions, and just coming away from ioo%. so can we get it down to 90%, can we get it down to 80% with something that's viable for the actual train operator to buy, save them money, reduce their emissions? and that's the perfect scenario, really. for companies maintaining our railway infrastructure, this new technology helps them to increase the working life of older machinery. the opportunity to use the technology that aht bring allows us to unlock older assets in a modern environment where we need to concentrate on our emissions and act responsibly. so effectively using a 60—year—old bit of kit in a modern way, without having to do lots and lots of expensive re—engineering and fit expensive equipment — it's a cost—effective way of giving us an opportunity. people watching might be quite surprised that we're still using 60—year—old trains. i mean,
