Boxcars was a criminal in Nipton who was planning to kidnap some NCR soldiers. Instead, they were ambushed by a group of Caesar's Legion soldiers led by Vulpes Inculta, who forced him and the other townspeople of Nipton to enter a lottery. The winner was let go while Boxcars got second place and, although allowed to keep his life, had his legs crippled by Legionaries. The rest of the gang members were either enslaved, crucified or killed along with Nipton's mayor Joseph B. Steyn.
If the player has a bad reputation with the Powder Gangers, Boxcars will give the player a not so warm welcome when first talking to him, referring to him as "the Powder Ganger's grim fucking reaper".
The player can give him some Med-X for his legs which, depending on how many doses given, will boost the Courier's Karma but will not affect reputation with the Powder Gangers. You can only give him Med-X once in one transaction. You can give him 1, 2, 3, or 5 doses. 1 -3 will get you karma and he will use them to heal himself. 5 will result in "A fella could put himself out of his misery with 5 doses." + karma, though he will not die.

Boxcars will not attack if you are wearing Legion or NCR armor.
It is notable that while giving him Med-X, regardless of his evil reputation, will reward you positive Karma, killing him will also result in positive Karma.
Attacking Boxcars reveals that he is in fact able to stand, and indeed able to fight, although he limps on one leg and walking probably causes him unbridled pain.
He claims to have his legs broken, but when targeted in V.A.T.S., his legs are in perfect condition.
This is no longer the case with the Lonesome Road add-on. His legs are shown to have almost completely depleted health.
If after killing Boxcars and putting him in the upstairs bathtub, upon loading an autosave of entering the building, he will get out of his chair and proceed to swim around most likely to the stairs. He will then proceed to swim up and down them, in what seems to be an endless search for the bathtub.
As he swims around, it is still possible to interact with him and he will be accompanied with the swimming SFX. After interacting with him, he may try to sit back down into his chair which will then make it impossible to engage in conversation.
"First I get my legs smashed, then in walks the Powder Gangers' grim fucking reaper? What the fuck have you got against us, bitch?"
pcps3xbox360 Due to a scripting error, Boxcars' legs are not crippled, allowing him full normal movement if engaged in combat. This was fixed with the Lonesome Road add-on. [verified]
pcps3xbox360 Boxcars is set to respawn within the game. Respawning occurs every three days, and will reset his inventory (possibly changing his worn clothing) and resurrect him if he was previously killed. [verified]
