Just wondered if you have noticed all the rabbit hutches that you can see from the train window just before Limehouse (near the car racing thing). It is the left hand side windows you see them from as the train heads towards Fenchurch Street. There are two areas a little distance from each other full of hutches and I saw a bunny in one one morning, but usually can't see much as the train goes past quite fast! It seems weird to have them there because one yard definitely has no house attached to it.
