Part families
Engines, fuel, turrets, carts, train building, cash upgrades, and offline earnings appear in the official listing.
Build a Cart Tier List: Part Roles by Goal
This is a role-first decision list—not an invented engine-stat ranking. Choose what you want from the next run, then test one part-family change.
One change per run
A stable baseline makes it possible to see whether an engine, fuel, capacity, or order change helped.
Named parts and turrets
Exact named-engine stats and current turret behavior remain unranked until reproducible data is available.

FAQ
Build a Cart tier-list questions
Why is this not a normal S/A/B tier list?
Current public sources do not expose reliable part stats. A role-first order is more useful than invented numeric tiers.
What should beginners prioritize?
Make one working engine-and-fuel baseline before expanding the train or testing version-sensitive utility parts.
What is the best setup in Build a Cart?
There is no proven universal setup. Choose speed, distance, offline progress, or troubleshooting and test one change at a time.
What is the best engine?
No reliable current engine catalog with comparable stats was available, so this page does not rank named engines.
