Thank-you merelynn. I'm hugely relieved that some of this writing worked for you - and that the pace came across. It's a real train, and it really does feel like that, travelling in Winter, as if it's hurtling forwards under hills - in real life it also then reaches a Victorian Viaduct which is higher than trees and I always have a slight panic about the train plunging off - when I look at the rails from my local station platform they're date-stamped with 1942 - I worry about the infrastructure of rural transportation links in the UK. Onwards!
