Frostrain 2 has 201 actual train-carriage entries: 191 upgrade levels and 10 fixed-level or special carriages. Supply items, selection tickets, cookies, and one-use action cards are excluded from these tables.
How to read the tables
Tier is the carriage’s Tier 1-4 card quality. Level is the upgrade level within that carriage model. Copies is the number of Level 1 copies needed to combine into that level. Space is the train capacity occupied, and Passengers is the maximum number of passengers who can work there.
The listed Happiness and special-effect numbers are the carriage’s base values. Artifacts, synergy bonuses, overperformance, and other run modifiers can change the final result.
Synergy activation thresholds
Synergy levels activate when the required number of matching carriages is deployed. Later rows replace or extend the earlier effect at the higher threshold. Neutral carriages do not have activation thresholds.
