A readerboard on the front of a London train, and signs on the tube stop platform, show the train's final destination. By ascertaining the train's final London destination, you can find its line and, subsequently, whether your stop is on it. Each London train line/route has a color -- as in red or brown -- which makes it simple to follow its route on a map.
Find a London tube map to find the direction you're bound and follow signs to tube tunnels within the train station accordingly; follow the tunnel and you'll wind up on the right platform to board the right train going the right way.
