UP 1644
Title:  UP 1644
Description:  UP 1644 triplet currently trailing up the hump heading up and over to grab the first group to shove up on this east (bound) taller hump (65 feet high if I remember right); the distant rail over-pass is used to get from the middle (after the under pass below this hump in a tunnel) over to the north side of everything (and the westbound section of the yard).
