Fix Techtonica MonoRail: What am I doing wrong?

Techtonica is a first-person factory automation game set beneath the surface of an alien planet. In this game, players work alone or in co-op to build factories, gather resources, research new technologies, mold the destructible terrain, establish a base of operations, and uncover long-forgotten secrets. However, some players are encountering issues with the MonoRail system. This article will explore the common problems and provide troubleshooting solutions.

Issue with Voltage Stepper

One of the primary issues players are facing with the Techtonica MonoRail system is related to the Voltage stepper. After troubleshooting on Discord, it appears that the problem is associated with this component. To temporarily rectify this issue, you can try a workaround by having your monorail sender on a separate grid that has accumulators and cranks, without any cables attached to the grid.

Setup Overview

The next step is to examine your setup and ensure that it meets the required specifications. Here is an overview of the setup provided by one of the players:

  • Power generation at WaterWheel section
  • Monorail depot on the same powered floor
  • A pre-existing voltage stepper connected to High Voltage cables
  • The cables are connected to a pre-existing accumulator block (near Victor) and additional accumulators
  • This cable is also connected to the voltage stepper at the Atlantum mine
  • The miner is running and is on the same floor as the second Monorail depot
  • The depots are connected via rail

Troubleshooting: Available MJ and Accumulator Bank

The issue reported is that both depots show 0 MJ available, with a requirement of 42 MJ, despite having 290 MJ in the accumulator bank. To further investigate this problem, the following steps can be taken:

  1. Examine the connection between the voltage stepper and the High Voltage cables. Ensure they are properly connected and there are no loose connections.
  2. Check the integrity of the cables themselves. Look for any damage or disconnections. Replace any faulty cables as necessary.
  3. Verify the power flow from the WaterWheel section to the monorail depot. Make sure there are no blockages or obstacles that can disrupt the energy transfer.
  4. Inspect the voltage stepper at the Atlantum mine. Ensure it is functioning correctly and receiving enough power from the accumulators.
  5. Confirm that the miner is running smoothly without any technical issues. A malfunctioning miner can cause disruptions in the power supply chain.
  6. Confirm that the rail connections between the depots are properly established. Ensure there are no gaps or missing rail sections that can cause disruptions in the power transmission.

If after attempting these troubleshooting steps, the issue persists, it is recommended to seek assistance from the Techtonica community or support team. They can provide specific advice based on your setup and offer further troubleshooting steps.


Fixing the Techtonica MonoRail system requires a thorough examination of the setup and troubleshooting the root causes of the issue. The problem with the Voltage stepper seems to be a common factor, and a temporary workaround has been discovered. However, it is important to thoroughly investigate other components and connections to ensure a stable and efficient power supply for the MonoRail system. By following the troubleshooting steps outlined in this article, players can have a better chance of resolving the issue and enjoy a smoother gameplay experience in Techtonica.
