For that size layout you really don't need all these power feeds, that's overkill. Fastrack has a common issue with connections between tracks. Lionel did a video that basically says to slightly bend the center pin TOWARDS the rail with the outer pin. That will eliminate your connection issue. Just bend them only slightly. They are made of pot metal not solid metal and will break off if you try and bend them too far. Do that on each track and your connections will be fine. You can also just run a wire between each piece having the issue since all fastrack has terminals on the bottom to make connections. Saves a lot of wire than doing feeds.
