The number of enemies behind rail carriages makes this a little tricky to adequately liberate without giving away your position. Enemies are particularly close to the alarms, and the east one is almost impossible to shut down without clearing the enemies first.
You can zip-line down from 
to the north, though you’re easily spotted. Use this location to gain knowledge of enemy locations, before creeping down and using the open rail carriages as cover.
Check the billboard 
for a scoped rifle and easy binocular tagging. You can direct a co-op friend to cause a distraction while you snipe foes, starting with those on the roof and near either alarm pole.
The water tower 
is a good place to ascend and rest if combat is getting messy; there’s items up here and it’s reasonably safe, plus you can drop grenades and fire down from this point easily.
Don’t forget to loot the blue upturned rail carriage to the northeast after the battle, or use it for cover during the fight.
Undetected/NoAlarms: The two alarm poles are your major concern, especially the one in the center of the rail yard. Start by crouching at 
, tagging foes, and removing the two foes on the ground floor of the main warehouse first. Then grapple to the roof, or climb the ladder at 
. You can then silently shoot the remaining foes from this rooftop using a bow, beginning with the enemy patrolling the top of the train carriages. Or, you can drop down, pull the enemy off the ledge of the open railcar (near the cult note on the pallets), and then work your way east, shooting the east alarm if necessary.
