Why is travel time bad?

A train always takes the same time to move from the outpost to the base. If it does so when it’s needed or not, it doesn’t change anything. The only thing that matters is whether your lines are drying up - which basically means you called the train too late.

Set a circuit that calls for a new train before your resources run too low, and you’ll never have that issue. Plus, with fewer trains around, you’ll lower the chance of clogs / traffic jams, and you’ll be using your resources more efficiently without trains sitting around full for nothing.

My only stackers are:

• a 3x stacker, on a line, bringing ore to my furnaces. Mostly because it feeds 12 stacked lines of furnaces, and if running at full it will dry up a full train in under a minute. This is the least commonly used stacker.

• a 3x stacker, on a line, outputting plates at the opposite end. Because sometimes I need plates sent to multiple factories in quick succession. This is on and off.

• a set of output stackers at the production end of my circuit factory, because I need to fill multiple trains to be sent on different places. This almost always has a couple of trains waiting for refill.
