Bulk mustard gas storage drums are stacked outside the tunnel to the left. On the right-hand side of this entrance was an equipment store. The reasons for using tunnels to store these weapons was clear to chemical warfare armourer Frank Burkin, who said, “…it seemed to be plain enough to me. First of all, it was material that was obviously top secret anyway, and the cooler you could keep it, the better it was. Also, by having it in tunnels, it was virtually unattackable—it couldn’t be bombed or whatever because all the tunnels had big heavy wooden doors, huge things which used to shut at night-time. And I don’t know how thick, probably two inches or more thick these big wooden doors. So virtually it was locked away.” Mid-1943. © National Archives of Australia156 • May 2008 • AUSTRALIAN RAILWAY HISTORY • Bulletin of the Australian Railway Historical Society

Originally open-sided sheds, walls were later added to protect stocks from the driving rains experienced at this locality, although, to allow air circulation, the sheds were not totally enclosed.
