Tonight I've had to reassess my misgivings about this intersection though. I've just entered Reservoir into Map of the Dead, the interactive map of places around you to help you survive the Zombie Apocalypse, and it would appear that when the forces of the undead take grip of our city, the Cheddar Road intersection is actually one of the best places you could position yourself.
And of course if you happen to find yourself on the opposite side of the level crossing to the Zombies, you may as well just carry on as usual.
