I've been having a think about gradients and all the advice I've had about it. I was originally planning to drop about 2 feet in too short a distance so I've been scratching my head about how to gain some more distance and I think I've cracked it. I've done a sort of a plan but basically if I re arrange the other side of my garage I can take the line round the end of the room on a removable bridge past the door and have Port Lucy on the opposite side of the room from St Ruth. This will give me an extra 6 feet or so of main line and it can be higher up as there won't be layout above it. It will also leave extra room for carriage sidings and a loco shed where Port Lucy was previously to be.
