So I was watching Thishttps://www.youtube.com/watch?v=DOg4m2YFtk8 video on youtube when I was bored. Can anyone explain what the Double Track Upgrade is that appears at 3 minutes 14 seconds? Why have I never seen it?

In the alpha a Line was default connected to 1 locomotive.
So, if you wanted more as 1 locomotive, you needed the "double track" upgrade to get 2 locomotives on a line.
So in alpha you could only have 1 loco per line without this?
Yes, that was the case.
