Reducing the time a station takes to disable transport mode

[hqz]

I'm trying to reduce the time a station takes to disable transport mode. So far I found data/scripts/entity/utility/transportmode.lua where there's the following variable:

self.restorationTime = 10 * 60

It seems to be referenced in most of the functions that deal with the delay I'm looking to change. However, when I change it to a lower value (e.g. 1 second), it still takes 10 minutes to disable transport mode. Am I missing something or am I looking at the wrong script? Is it possible that the script (or some of its data) is persistent despite reloading the game? (I haven't tried yet on a brand new game to confirm this)

Note: I have modified the game's script directly instead of making a mod so far because I wanted to test things first. I already did something similar to make the "refine ores" command faster and it worked without making it a mod while I was testing it. So I don't really know what would be different here.
