With access to the mine carts following the Classified Arms Reloaded update, players will be able to travel from one POI to another incredibly quickly. This new method of instant transportation is called the Underground Transit System, and here is where you can find all of the mine carts.

In a Season 3 teaser, players got their first glimpse at the underground mine cart system beneath Caldera. Following the Season 3 Reloaded update, this system will finally come into play. This new tool is an instant way to get around the map for quick rotations or outmaneuvering your opponents.

Once you access one of the 14 Underground Transit locations, you must simply enter a hatch and interact with the mine cart to travel to your new destination. Once you are close to the cart, “the destination name will appear on your screen – After a few seconds of travel time, you’ll instantly appear at your destination.”

Interestingly enough, players can use the light and audio clues to discern if there’s an ambush waiting for them at their next destination. A green light indicates that the coast is clear, while any other colored light hints at danger. Evidently, if the indicator is off with no information to deliver, you cannot travel to that destination.

As you can see from the image above, there are a total of 14 access points across the map. If you’re wondering what access points look like, you’ve likely seen one before. It turns out the Nebula 5 bunkers you’ve seen around the map for months now are the key to accessing seven of the points on the map.

Meanwhile, “the other seven access points are small hatches into the mine-cart hub area. Here, you can find a map of the system, with each hub location corresponding to a letter and number on your Tac Map.”

The Underground Transit System‘s access points will be viewable through your in-game map. They will be indicated on the Tac Map and minimap by a silver “vault door” symbol. Here are all of the mine cart locations across Caldera:

  • Runway
  • Ruins

Almost every major POI across Caldera will have a mine cart access point. However, it is important to note that not all locations offer several destinations. Of the 14 access points, only Docks, Peak, Fields, Mines, Sub Pen, and Airfield offer multiple options when it comes to the destination.
