Train Cars, Merging & Module Slots

What each train choice changes

• Buy a car: stations offer new cars alongside other purchases.
• Reorder cars: change the arrangement of your train.
• Merge cars: strengthen cars and unlock additional module slots.

Merging and buying a weapon answer different questions: one changes the car and its capacity; the other adds a combat option.

Before you spend

Use this as a decision checklist, rather than a ranked build: do you need another car, an improvement to an existing one, or equipment for the current train? Read the in-game offer before accepting a merge. The store description does not establish exact merge recipes, tier requirements or slot counts.

After changing your cars

Review the weapon and drone options for the train you now have. If a resumed run is missing trade rewards, install the developer hotfix before treating the missing reward as a merge rule.
