Boxcars was a criminal in Nipton who was planning to kidnap some NCR soldiers. Instead, they found Caesar's Legion 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, he was allowed to keep his life, he had his legs crippled by Legionnaires. 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, from 1 to 5 doses.
pcps3xbox360 Due to a scripting error, Boxcars' legs are not crippled, allowing him full normal movement if engaged in combat.
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.
pcps3xbox360 Sometimes after giving or not giving him Med-X doses he will no longer have a dialog option other than "Good bye", thereby breaking the Wheel of Fortune quest.
