Megabase Modular Train Grid Framework (Vanilla)

Updated for Factorio 2.0 WITHOUT Space Age - reworked the whole rail grid system

These blueprints will allow you to easily and quickly migrate your existing base from first rocket launch to megabase.

All factories are defined within blocks, surrounded by rail grid that can be connected on any side in any way. Each factory has stations to bring necessary goods in, and output station with trains ready to get the goods out. Trains will wait on their loading station and deliver to unloading station when the resources are needed. Unloading stations have circuit logic that will set the train limit depending on how many goods are stored in the chests. Logistic network is used mostly for construction, and to transport ammo. Everything is under one big network.

You can start by placing grid base layout for fast expansion of the power and logistics network. Then you can place factories on top of those wherever and however you like it. They can be rotated in any direction. Sometimes you’ll have to clear power poles for factories that takes more than one grid space, or radar if it’s in the way. If some factories are built further apart, they can be connected with the simple rail line blueprint.

With these blueprints, most of the factory can be built from the map view and you don't necessarily need to be near the construction spot. Raw resources can be gathered with the generic loading station and choosing the desired resource. All you need to do then is connect your mining drills to the stations by using provided blueprint helpers for belts. It's important to use a lane balancer before the station to equalize the consumption or loading of the resources between wagons.

Before you begin the transition, all technologies should be researched, and make sure that you are producing nuclear fuel and a lot of speed/production modules. You should build factories for the Mall, Modules, Nuclear processing, Stone processing, and Ammo before you destroy those in your old base.

Science builds have the 1k/m version that can later be upgraded to 4k/m.

To avoid you some calculations, for the 1k/m science you'll need:

• 2 Low density structure factories
• 1 Rocket Fuel factory
• 1 Batteries factory
• 1 Blue circuit factory
• 2 Red circuit factory
• 6 Green circuit factories
• 3 Plastic factories
• 1 Sulfur factory
• 4 Steel smelting factories
• 6 Iron plates factories
• 8 Copper plates factories
• 1 Stone brick factory
• 3 Oil processing factories

And for the 4k/m:

• 9 Low density structure factories
• 3 Rocket Fuel factories
• 2 Batteries factories
• 2 Blue circuit factories
• 4 Red circuit factories
• 14 Green circuit factories
• 6 Plastic factories
• 2 Sulfur factory
• 14 Steel smelting factories
• 14 Iron plates factories
• 24 Copper plates factories
• 1 Stone brick factory
• 8 Oil processing factories

This does not take into account the resources you'll need for the mall and modules or defenses, so you'll probably have to add more depending on your needs!

You’ll see green and red wires being connected through the whole grid. Green wire contains the number of items waiting in station chests to be picked-up. Red wire contains the number of items each factory will request (in negative) and provide (in positive) so that you can estimate which factories or resources you’ll need to build/provide.

There are defensive perimeter blueprints that can be used around the base to defend yourself. It will receive ammo and supplies with bots.

This is designed as a framework for further improvements. You can of course build your own version of any factory or create new ones. (There is for example no factory included for personal equipment construction)

Some rules that should be followed:

• Factory is surrounded by basic train grid line – This will assure that other factories can be built on any side and connect to the grid.
• All stations are aligned vertically for easier blueprinting and station placement. There are blueprints provided for different number of stations that can be used as base for new factories.
• The grid train line has waiting space for one train in each direction. Grid is designed for maximum 5 length trains.
• The loading stations should have 1 queue and use 2 trains – This allows the first one to get filled and leave, then the next one can get its place and start filling. Usually, the first one gets back before the second one is filled and then it cycles.
• Station naming is important as it defines which trains are needed or where they need to go – The system will ask for any train anywhere that is ready to deliver the needed goods
• Loading and unloading stations templates are provided with circuit logic – Only parameters to configure are “L” for max train queue (1 if no queue, 2 if there is one queue) and “W” for number of wagons.

Some parts of the factories are using blueprints that I have found in the community. Biggest credits goes to Nilaus for his master class blueprints, but also to Rahbek for the mall and Yoyo Ma for the nuclear power plant. Special thanks to Azaghal for some help in early design and adjustments of the base grid system.
