Somewhere in my stack of vinyl I think I still have a record of the Royal Hudson. First side was recorded from the cab with all the conversation, sounds and action. Side B was from the outside - working its way up a hill, rolling by at speed, whistle blowing with answering calls from nearby fog horns, etc.
If anyone is interested, I will see if I still have the thing and pass it on to you. It really was an interesting record.
