I bring you good news CFUKers
The Spawn -> Mesa railway is functional! While not aesthetically complete, it will, for all intents and purposes, take you from point A to point B... or the other way around, if you wish. The trip takes about 2 minutes 20-30 seconds if you want to AFK it while you make a Hot Pocket or something.
Additionally, the rail is long enough that it will get you the achievement "On the Rail". How nice
While I can't say it's a Grand Opening until it /done/ done, you may now use it to reach the Mesa. Thanks to all who have contributed and are still contributing as the rail nears completion!
A side note: Geez, it's been 2 weeks since this thing started. Quite an endeavor, don't you think? xD
