Wolvercote Tunnel passes under Wolvercote Roundabout in the north of Oxford. The ex LNWR Bletchley to Oxford railway passes through the tunnel. When the line became less used, it made a perfect roosting place for bats. On reconstruction of the line for the Chiltern Railways new services to Oxford, the tunnel was refurbished and equipped with 'Bat Lights' which are triggered by the passing of trains. This is to persuade the nocturnal animals to remain at roost when a train passes and not fly off and possibly get injured in the process. The 'Bat lights' are fitted along the tunnel walls and on posts at the entrances to the tunnel, as seen here.
