Train Track Nexus 3D

Build a connected railway ahead of the moving train and reach all 50 stations across five landscapes. Lay track on land, build a bridge over water before laying rails, and drill through rocks. Bitcoin-logo pickups award 100 game points each. These are fictional points with no monetary or cryptocurrency value.

Controls and starting a run

Choose the left, centre or right route, then operate the tool highlighted by the terrain: Track on clear ground, Bridge over water, or Pulse drill through rock. Water and rock still need Track after preparation. On keyboard, A/D or left/right choose the route; 1, 2 and 3 operate the tools. Hold Space or the up arrow to boost and hold S or the down arrow to brake. Menu or P pauses, C cycles Wide, Chase and Driver cameras, and F opens fullscreen. The three-step simulator can be replayed from How to play.

Scoring and strategy

Watch the tracks-ahead meter. Build several sections before holding Boost, then Brake early if unfinished guideway is close. Every construction press performs one visible job, so prepare water or rock first and then press Track. New tool tiers unlock after levels 5, 15, 25 and 35. Your total ranking is the sum of your best score per level; only improving a best score earns more upgrade points. The server verifies each run and shows the shared top 10 after a win or loss. Use a nickname you are comfortable making public. Progress is linked to this browser with a cookie; the simulator and practice mode do not save scores.

Your first three practice goals

These are optional practice exercises, not extra in-game missions or rewards. Try one at a time so you can tell what improved.

  1. Replay the menu’s How to play simulator before a scored level. Practise choosing a route, preparing water with Bridge or rock with Pulse drill, and finishing each section with Track.
  2. Use the Wide camera to inspect the three routes. Build several sections ahead, hold Boost on a clear line, then Brake before the tracks-ahead meter reaches two.
  3. After a level, compare the result with your previous best before spending upgrade points. Improve an unfinished or low-scoring level rather than assuming repeated identical runs increase your total ranking.

A common mistake to avoid

Waiting until the engine reaches unfinished track removes your planning time. Automatic slowing helps while constructing, but it is not a substitute for a connected route. Finish the demo in practice mode before risking a scored run.

Play comfortably on your screen

Open the game with the Play link, then use Fullscreen in the toolbar for more space. On phones, pause before changing orientation. On computers, click inside the game before using keyboard controls. Touch and keyboard availability differs by game; use the controls described above.

For a blank game, missing progress or trouble leaving fullscreen, visit player help. A TV browser may need a connected keyboard or pointer; a remote alone is not a substitute for the game’s controls.
