System Modernization Program — 2026

The same station.
Sixteen years apart.

Drag the rail to compare what your network looked like in 2009 — and what it can look like when the next capital budget cycle closes.

01 — Signaling Infrastructure

Headway is the
measure of capacity.

Fixed-block signaling from the 1980s caps your throughput regardless of fleet investment. Communications-Based Train Control removes the ceiling — trains follow each other by position, not fixed territory.

CBTC deployment on 6 core lines recovers 14 train-minutes of capacity per peak hour — equivalent to running 2 additional trainsets without purchasing new rolling stock.

02 — Rolling Stock & Dwell

38 seconds becomes
22 seconds.

Wide-aisle rolling stock with four-wide door clusters and predictive door-hold logic. Each second recovered at 187 stations compounds into network-level throughput.

03 — Energy Recovery

Every brake event
generates revenue.

Regenerative braking on modern rolling stock returns traction power back to the third rail. At 4.1 million daily trips, the compounding effect makes energy recovery a capital budget line item, not a sustainability footnote.

04 — Platform Screen Doors & System Status

The edge of the platform
is now a sealed system.

Platform screen doors eliminate track intrusion, reduce HVAC load by 18%, and allow dwell-time optimization by removing the human margin from door-hold decisions.

The cost of inaction
compounds every quarter.
