Here's another possible angle:
Magic Kingdom's Space Mountain in Florida is actually 2 coasters under 1 roof, with 1 side being an (almost) mirror image of the other side. The 2 sides are called Alpha and Omega. Obviously, KI is building 1 coaster, but I think it would be a great idea to name the trains Alpha and Omega. Just imagine... "Hey Omega! How was that ride?!" ...and the station is immediately filled with a roar of cheers and applause!
How many days until 2020's grand opening?!
