regarding the Dimensonals on the shore, this served 2 purposes. The train wouldn't have to find a hole to get into to meet an opposing movement, or passing movement, and tie up one of the 2 mains while it was down there. there are 2 through truss bridges, one over state street and the other just west of the 490 underpass which are fairly close clearance. Not to mention that Rochester gets congested fairly often with it's own traffic without adding one of these to the mix. The "Shore" was a convenient place to send them and move about 20 miles without interfering with normal op.s.
Harleys and EMDs, some of my favorite rides
