My translation might be off just a tad:

Iz comin like big trayne very fast on trak so all who need to no mus git off of trak zo not to be ron down. If u wan too git on trayne mus do so soon becuz trayne leaf and no com back.to pik up sleepy. Wake up, tickees cheap, no many to bye almoz ol solt out. Sun com up soon an lite way to stars. Vely brite, mus wear shaydes. Sleep goot nitey tyme. Big smyle on hapi fays.
Listen o no listen. No soop for u. Han no fool.
