After you leave the subway for the two fuses you get to a 'hub' of sorts where you can choose two paths to take. One of them leads back through the park and to the first subway, and I reckon thats the fuse you've 're-found' of the two. If you take the other path you'll reach a street with a red bus blocking the street, jump out the window and follow the path, it will lead you to Ronald street eventually
