How to Attach Trailers in Lightyear Frontier
Connect a trailer to your mech, distinguish towing from chaining, and troubleshoot hitch targeting before a long hauling trip.
Aim at the hitch, not the cargo
Bring the mech close to the trailer's coupling and look for the contextual attachment prompt. Use the interaction shown on screen. If the game highlights a cargo item or the trailer body instead, adjust your position until it selects the connection.
Attaching one trailer to a mech and chaining several trailers together are different operations. A trailer that can be towed is not automatically capable of forming a train with every other trailer.
Connect a single trailer
- Park on open, reasonably level ground with space behind the mech.
- Approach the coupling end of the trailer rather than its storage area.
- Aim slowly around the hitch until the attachment indicator appears.
- Confirm the prompt, then move forward a short distance.
- Check that the trailer follows before loading valuable materials.
Use the current HUD prompt instead of relying on a universal keyboard shortcut. Control mappings, input devices, and the targeted object can change the action offered.
Connect a trailer chain
For compatible higher-tier trailers, bring the front coupling of the next trailer close to the rear of the attached one. Target the connection between them; if the indicator points back to the mech, you are selecting the wrong link. Step back slightly or approach from the side until the intended pair is highlighted.
Player reports identify tier-II trailers as the relevant chaining upgrade in the earlier hauling system. Check the trailer variant available in your present build rather than treating an old milestone number as its unlock condition.
If the prompt never appears
Try an empty trailer on flat terrain first. Move other objects away from its hitch, check the trailer variant, and test one connection at a time. This separates a targeting problem from a compatibility problem. Repeatedly pushing loaded trailers together makes the result harder to diagnose.
The 1.0 trailer overview on the HUD helps you inspect a connected train. Before a long trip, make a wide turn and cross a small slope near home. If a connection is unstable, solve it while your cargo is still easy to retrieve.
Plan a recoverable hauling route
Leave room to turn beside your storage and processing machines. Prefer a tested route over a short cliffside shortcut. If a trailer becomes unreachable, Lola's retrieval service can recover lost trailers for a fee; consider that cost before sending a fully loaded train into difficult terrain.
Pair your hauling setup with a Mineral Extractor and a repeatable iron route.
