Station Seven

Station 7 was a resistance underground railroad station located at the beginning of the Canals leading out of City 17. Station 7 is seen in the beginning of the Water Hazard chapter in Half Life 2.

Location
One of the few stations located on the Canals itself, Station 7 is the first building seen in the chapter Water Hazard. It is located on a bank near what might be a small farm with several buildings and a red barn.

Features
Station 7 was used by the resistance as a refugee aid station before the destruction of City 17. The main building used is a large red barn on a few docks on the shore of the Canals. The red barn contained a high crane operating area, which could have served as a lookout, and several tables inside with a radio, common among resistance refugee stations.

Station 7 also appears to have several buildings behind the barn, blocked off from the shore by a fence. These buildings could have served as barracks for the resistance members stationed there. It is possible Station 7 was used as a farm before the Combine invasion, as there is a barn and the canals could have served as transportation of produce, and the buildings behind the barn could have been living quarters.

Half Life 2
When Gordon Freeman arrives in City 17 and has to make his way through the Canals, Civil Protection had been finding, raiding and destroying resistance underground railroad stations. Station 17 is one of the unlucky stations unfortunate enough to be hit by a headcrab shell bombardment.

As Gordon Freeman arrives at Station 7, told by a resistance member in the previous station that he would find help here, he instead finds hostile headcrab zombies which were the result of a headcrab shell that had crashed through the barn's roof.

It is possible that the buidlings behind the barn were also hit by the bombardment, and had become infested with headcrabs and possibly more zombies.
