Calculating Freight Train Size & Buffer Theory
If you use trains to transport resources then you are going to want to make sure the train can supply enough resources to last the round trip. This video explains how to calculate this along with a working example. This video also explains the theory behind using buffers for the freight platforms.
Train Fluid Platforms with Fluid Buffers
Train freight platforms will cease input/output operations when a load/unload operation occurs. This video shows how to use fluid buffers with train fluid platforms to ensure your production line will always receive fluid during load/unload operations.
Build Train
A build train is central storage on wheels. It really helps when building at a remote location, you have everything you need on hand.
