In addition to what others have said (which is correct) that still means you have to unload every train and reload another at the point where they meet. In the days before the modern standard container that took a good amount of time. Additionally it means you had to run twice as many trains (meaning twice as many engineers, a lot more maintenance, separate production lines for parts etc.) it just made things a ton more difficult.

Is it arrests? It sounds to me like it’s suspects that they are looking for

They also report crime and police related pages are going to post suspect info. You’d care more about crime rates than arrest rates.

Why use arrest rates and not crime rates?

What happens if you only average over 8k steps? For instance I get 14k steps but only 4 times a week

This is the case, though it should be noted that the soviets did not have a separate gauge for military purposes, but just because the Russian Empire decided that the wider gauge was better for because their country was so flat and the distances between cities so great. That it slowed down the Nazis was a happy accident.
