Why we're doing it
Some of these changes are related to our ongoing effort to modernize signals on the line. While service is suspended, our crews will work on installing equipment, including cables, that will support the new signaling system.
Other changes are related to ongoing accessibility improvements, structural work, and track maintenance, which is necessary to keep the line in a state of good repair—and ensure you have a smooth ride.
