Quality Trains

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_size and quality_affects_capacity flags
• No runtime scripting — pure data stage, zero performance impact
• Works with modded wagons — all cargo and fluid wagons are affected

## Localization

Fully localized: English, German, French, Ukrainian, Russian, Chinese, Japanese, Korean, Polish, Spanish, Portuguese, Czech.
