Electrification, Centralized traffic control (CTC), and Positive Train Control (PTC) allows for better tracking and handling of trains and their movements. The technology allows for quicker acceleration and braking, permits trains to run closer together.
** The combined improvements envisioned by Solutionary Rail will add capacity and fluidity to the rail system, electrification being one component. Others are double tracking, realignment of curves, and capacity constraint projects (tunnels and bottlenecks).
