To be frank, I have a lot of ideas, and not much space to work with.
But if I ever got the big room-space for it, I'd be able to fit in a lot more of the ideas I had; for instance, some of the industries I had in mind for the area around Christchurch Road station were the inevitable coal merchants within the goods yard, a building supplies firm (selling bricks, timber and glass for construction work), a brewery, and a few other bits and bobs of light industry like a cooper's workshop, up to and potentially including a small boat yard- that last one is in part because there's a privately owned tramway (akin to the Wisbech and Upwell) running out to a fishing village a few miles away on the coast, which also connects to some of the local farms, which is where most of the agricultural traffic comes from (wheat, sugar beet, potatoes and other vegetable crops).
