Hi,
It has only been recently (past 10 years or so) that I realized that Tennessee Pass was higher than Moffat Tunnel. I can understand why the Rio Grande wanted the former D&SL and built the connection from Dotsero.
Not only was the run to Denver shorter but also a lower elevation crossing the Continental Divide.
