Dead Rails ends when you reach the fort at the 80,000 meter (80 km) mark in the game, which is located at the Mexican border in the zombie-infested desert. Upon arrival, you will see a heavily fortified place full of hostile Outlaws. You cannot simply drive through; instead, you must lower a huge bridge to proceed. The key steps at the ending are:

• At least one player must leave the train to trigger the bridge lowering mechanism.
• Once triggered, a countdown of four minutes begins.
• During the countdown, waves of zombies and attacks from Outlaws will try to stop you.
• You must survive until the countdown reaches zero.
• After the bridge is fully lowered, you can exit and have essentially completed the journey to safety.

This marks the conclusion of the Dead Rails game experience, signifying that you have made it through the desert to the end of the line.
