Railway Role Expansion

Railway Role Expansion is a Factorio 2.0 mod that makes railway logistics more intuitive while giving each class of rolling stock a distinct role.

It rebalances the vanilla train roster and introduces two specialized vehicle families: Industrial vehicles for heavy-duty, short-distance operations, and Linehaul vehicles for high-speed, long-distance transport.

Vanilla trains remain a comfortable all-purpose choice, while the new vehicle classes allow you to optimize your railway network for different operational needs and playstyles.

This mod is an independent Factorio 2.0 derivative of Optera's MIT-licensed Train & Fuel Overhaul (Train Overhaul). The original fuel overhaul mechanics have been removed, with the focus shifted entirely to expanding and rebalancing trains and railway logistics.

Main Features

Improves the performance of vanilla locomotives, cargo wagons, fluid wagons, and artillery wagons
Adds industrial locomotives, cargo wagons, and fluid wagons
Adds linehaul locomotives, cargo wagons, and fluid wagons
Adds the Improved locomotives and wagons technology to unlock the new vehicles
Provides startup settings for train weight, locomotive power, classic train sounds, and hand crafting

Vehicle Roles

The standard vanilla-style train set is adjusted to make rail transport comfortable on its own. Choosing Industrial or Linehaul vehicles then lets you further optimize your railway network for specific use cases.

Class	Use case	Characteristics
Standard	General transport	Versatile baseline vehicles tuned to be easier to use
Industrial	Factory interiors, short routes, heavy loads	Lower top speed, with stronger acceleration, durability, braking, and capacity
Linehaul	Long-distance, mainline, high-speed transport	High top speed, with lower traction, durability, efficiency, and braking performance

Typical usage:

Standard
Short-distance transport through artillery wagon service
Works well with a wide range of consists such as LCC through LCCC
Industrial
Useful for short consists such as LCC or LCCL where acceleration and braking matter, especially inside factories with many intersections
Large-capacity wagons reduce the number of round trips even with shorter trains
Linehaul
Useful for long-distance transport built around longer consists such as LLCC or LLLLCCCC
Wagons have lower capacity, but dedicated direct routes that allow trains to maintain top speed can provide faster throughput

Main Stats

The following values assume startup multipliers are set to 1.0.

Locomotive	Top speed	Power	Health	Fuel slots	Role
Standard locomotive	345.6 km/h	1.8 MW	1000	3	General
Industrial locomotive	237.6 km/h	4.0 MW	1200	2	Heavy-load, short-distance, strong acceleration/braking
Linehaul locomotive	604.8 km/h	1.3 MW	800	4	Long-distance, high-speed mainline

Wagon	Top speed	Capacity	Health	Role
Standard cargo wagon	345.6 km/h	60 slots	600	General cargo
Industrial cargo wagon	237.6 km/h	80 slots	800	Large-capacity cargo
Linehaul cargo wagon	604.8 km/h	50 slots	500	High-speed cargo
Standard fluid wagon	345.6 km/h	35,000 fluid	600	General fluid
Industrial fluid wagon	237.6 km/h	40,000 fluid	800	Large-capacity fluid
Linehaul fluid wagon	604.8 km/h	30,000 fluid	500	High-speed fluid
Artillery wagon	324.0 km/h	-	1000	Artillery transport

Technology and Recipes

Additional vehicles are unlocked by the rre-improved-trains technology.

Prerequisite: braking-force-2
Research cost: 400 sets of automation, logistic, and chemical science packs
Research time: 30 seconds

Additional vehicles are crafted by refitting existing vanilla train vehicles.

Industrial locomotive: locomotive, advanced circuits, productivity modules
Linehaul locomotive: locomotive, advanced circuits, speed modules
Industrial cargo/fluid wagons: matching vanilla wagon, productivity modules
Linehaul cargo/fluid wagons: matching vanilla wagon, speed modules

By default, train upgrades require an assembling machine. Hand crafting can be enabled with a startup setting.

Settings

Setting	Default	Description
`rre-weight-multiplicator`	`1.0`	Multiplier applied to train weight
`rre-power-multiplicator`	`1.0`	Multiplier applied to locomotive power
`rre-old-sounds`	`true`	Uses classic train sounds
`rre-hand-crafting`	`false`	Allows hand crafting for train upgrades

Compatibility

This mod changes vehicle prototypes, items, recipes, and technology during the data stage. It does not include any runtime control.lua logic.

Mods that change the same vanilla train prototypes, train recipes, train icons, or train sounds may conflict depending on load order and overwrite behavior.
