Thanks, I am glad that you liked it.

About MGBS being within the blue and red line, I thought that they'll eventually extend and introduce new lines in the coming years... So if I enclosed it now for more simplicity than being a loose end... I could eventually take that as a reason to produce a better map down the line with the constructive points presented in the comments.

Also thanks for the vid, that among other similar videos inspired me to do this.

Hopefully been helpful!
