Control points, sidings and turnouts were upgraded with state-of-the-art wayside systems -- improving on-time train performance by eliminating most signal failure delays.

How You Benefit
Cross GlyphImproves Safety
New state-of-the-art systems improve train passage and safety. The system also aids the implementation of the  Positive Train Control system, designed capable of reliably and functionally preventing train-to-train collisions, overspeed derailments, incursions into established work zone limits and the movement of a train through a main line switch in the wrong position.
Car GlyphRelieves Congestion
This projects improves train passage along the tracks, reducing delays due to signal failure and reducing overall congestion between freight and passenger trains.
