Quality now actually matters for trains! Wagon capacity scales with quality, just like most other items in the game.
## The Problem
In vanilla Factorio 2.0, quality on trains only increases health — a wasted opportunity. This mod fixes that.
## Cargo Wagons
Higher quality = more inventory slots.
| Quality | Slots | Bonus |
|---|---|---|
| Normal | 40 | — |
| Uncommon | 52 | +30% |
| Rare | 64 | +60% |
| Epic | 76 | +90% |
| Legendary | 100 | +150% |
## Fluid Wagons
Higher quality = more fluid capacity.
| Quality | Capacity | Bonus |
|---|---|---|
| Normal | 50,000 | — |
| Uncommon | 65,000 | +30% |
| Rare | 80,000 | +60% |
| Epic | 95,000 | +90% |
| Legendary | 125,000 | +150% |
## Scaling
All bonuses follow the standard quality formula: +30% per quality tier (with Legendary at level 5 = +150% total). Same scaling as crafting machines, inserters, labs, and
most other quality-affected items.
## Technical Details
- Uses Factorio's built-in
quality_affects_inventory_sizeandquality_affects_capacityflags - No runtime scripting — pure data stage, zero performance impact
