GTA 5 Sidetracked Walkthrough: Train Setup and Gold

Approach: The Big Score — Obvious. Start: Lester’s message about the railway equipment.

Sidetracked supplies the train used to move the gold after the Obvious version of The Big Score. The setup has two distinct jobs: divert the train without raising the alarm, then use Trevor’s heavy-lift helicopter to transport its engine and a flatbed carriage.

Step-by-step walkthrough

  1. Reach the railway siding quietly

    Follow Lester’s setup marker to the railway site in the Grand Senora Desert. Find both workers before acting. For Undetected, incapacitate them without allowing the second worker to raise the alarm. A suppressed weapon or a carefully placed shot from outside their sightline gives more control than charging directly between them.

    Do not enter an exposed position merely to save a few seconds. Losing the stealth condition cannot be repaired by escaping after the alarm.

  2. Divert the train

    Once the workers are dealt with, enter the control cabin and use the prompted track switch. Wait for the train to reach the siding. Follow the character switch into Trevor’s helicopter when the sequence advances.

    The target is now the train equipment itself. There is no need to drive the locomotive away or search for a separate road vehicle.

  3. Lift the engine and deliver it

    Approach the locomotive slowly, aligning the helicopter’s magnet above its centre. Lower into range and use the displayed magnet control to attach the engine. Gain enough height to clear the tracks and nearby obstacles before accelerating towards Trevor’s airstrip.

    At the delivery marker, reduce speed before descending. Release the load when it is correctly positioned; a low, controlled delivery is quicker than overshooting and having to circle back.

  4. Return for the flatbed carriage

    Fly back to the siding and repeat the lifting process with the marked flatbed. Bring it to the airstrip and place it at the destination to finish the setup. The gold time of 4:30 includes both journeys.

    Use direct flights with enough clearance for the suspended load. Abrupt turns and steep approaches can make the cargo swing, costing more time than a measured approach to the pickup.

Gold medal checklist

  • Time: Complete within 4:30, including both airstrip deliveries.
  • Undetected: Take over the railway tracks without being detected.

Common questions

Do I need to transport the whole train?

No. Take the engine first and the marked flatbed carriage on a second trip.

Is this setup required for Subtle?

No. Sidetracked belongs to the Obvious approach. Subtle uses Stingers and three Gauntlets instead.
