The Post Office Railway (Mail Rail)

From Silent UK – Urban & Underground Photography write about London’s quite extensive other Underground : The Post Office Railway (Mail Rail) : “For as long as I can remember, explorers have joked, discussed, cried themselves to sleep over possibilities the Post Office Railway could be explored. Those keen to attempt entry desperately clawing at every scrap of information like a starving hobo snacking on bread crumbs. Just the idea of access, let alone the task of traversing the line seemed fraught with impossible obstacles and doubt.”
