Here's your final look at Hearts of Iron 4's new supply system - now with trains

One of the key features of Hearts of Iron IV's No Step Back expansion and the free update is that it will completely overhaul the grand strategy game's supply systems. We were given an early look at the new supply system in April, with a follow-up in June just before the developers went on their summer break.

This weeks' dev diary offers one final look at the supply system - and it's all about trains, baby. Trains and the rail network as it is represented in-game will be instrumental to getting supplies to your troops on the frontlines. While trains can't always get supply all the way - you may need trucks to go that final mile - they are the backbone for getting supply to areas where the local supply is being overwhelmed by the number of troops in a region.
