SCR 2.0 Sneak Peeks: Mesh Upgrades, New Trains and Stations & SPECULATION!

SCR has been posting quite a few sneak peeks, most likely for the upcoming 2.0 update, and today I'll be going through all of the ones between the last few that I took a look at in the 2024 announcement and the most recent ones in mid-April. Additionally, I'll be providing a bit of my own speculation on some features of this upcoming update.

Stepford Connect is a Regional operator, not Commuter, and on the semaphore sneak peek you can see that it goes 1 track, and later merges with the main line
