Variable Removal

Variable Removal is a Railroad radiant quest in Fallout 4. It requires the Sole Survivor to go to a random location and eliminate a Courser. If left unchecked, a Courser could cause a lot of damage to the Railroad's infrastructure.

Detailed walkthrough
1. Eliminate the Courser

Your Pip-Boy will have been updated with the location of the Courser (they are different random locations). Travel to that location and eliminate the Courser however you see fit. The only kill required to complete the quest is the Courser's but you can kill all the Synths at this location without turning the entire Institute hostile.

2. Report back to Predictive Analytic Machine

Return to P.A.M. at the Railroad HQ. She will congratulate you on a job well done and give you bottlecaps and sometimes a weapon.

Possible locations

 * ArcJet Systems
 * General Atomics factory
 * Poseidon Energy
 * Reeb Marina
 * University Point
 * Wattz Consumer Electronics

Bugs
When P.A.M. is reprogrammed and brought back to the Prydwen, it may still initiate the quest. Not sure how to do this properly, but I'll verify this on PC, it happened outside the door to enter the Prydwen, as she arrived.
