Behind the scenes

 * Wernher may be a reference to S. D. "Snake" Plissken from John Carpenter's Escape from New York and Escape from L.A.

Bugs

 * There is a bug where Wernher, after killing all the raiders in the first battle upon entering the Pitt map, will continually shoot at the Pitt leader whom he first talks to whether or not she's dead already. He will eventually stop. This can also be resolved by saving and then reloading the save.
 * There is a bug in which Wernher's left eye is fluorescent yellow. This is sparked from approaching him from different angles. It's just a minor glitch that doesn't seem to resolve itself.
 * There is a bug where after killing all of the raiders Wernher will start walking across the bridge and get himself killed if the mines aren't disabled.
 * Wernher may inexplicably become hostile to the player. If so, he cannot be killed. The console can be used to fix this glitch on the PC. Xbox 360 users can wait outside his hideout for three full days to reset Wernher's AI, after which he will proceed normally.
 * There is a bug where after killing Wernher and going back to the Trainyard, you will see his dead body right next to the cart. (Confirmed on Xbox 360&PS3)
 * Wernher was confronted near Oasis, though this is yet to be confirmed. (Confirmed on 360)
