I went to school in Dover (mid '70's to early 80's) and the sound of the SRN4's is one of the sounds of my youth (along with punk rock). Watching them shoot the western harbour entrance when it was a bit choppy was great fun also.
I travelled in them a few times aswell, and also the aforementioned French monstrosity, which really did look like something out of sci-fi
