Unlocking capacity from existing infrastructure — through intelligent planning, live-run optimization, and real-time conflict resolution.
The most expensive capacity constraint in rail is not track geometry or fleet size — it is unoptimized train sequencing. When crossings are planned manually, on paper, one train at a time, the result is a network running well below its installed capacity.
ART’s Movement Planner replaces the paper train graph with a time-space optimization engine that simultaneously plans the best crossing sequence for all trains in the network. At the operational level, the algorithm continuously re-plans ahead in real time — reacting to deviations, disruptions, and priority changes before they cascade into network-wide delays.
The system operates across three planning horizons: strategic (capacity simulation and investment analysis), tactical (timetable optimization and maintenance planning), and operational (live-run crossing control integrated with the Active Train Control System). Plan and execution operate as one connected system.
– Live-run optimization algorithm — minimizes total transit time across all trains
– Real-time conflict detection and crossing sequence re-planning
– Strategic capacity simulation — models investment alternatives and demand scenarios
– Timetable generation with scenario comparison for tactical planning
– Train priority classification — mandatory, priority, and regular trains
– Speed restriction and temporary interruption management
– Overtaking detection for high-priority trains blocked by delayed consists
– Planned vs. Actual reporting — structured KPIs for PDCA performance management
– Yard arrival forecast — supports shunting and terminal planning
– Full integration with Active Train Control
While others simulate, ART optimizes live operations — connecting strategy directly to daily execution.

Plan and execution operate as one system — from the annual timetable to the next crossing sequence, six minutes ahead.
– Significant increase in trains per day without new infrastructure investment
– Reduced total transit times across the network
– Elimination of manual paper graph — faster, more consistent decisions
– Better recovery from disruptions — real-time re-planning under variability
– Improved yard and terminal planning — advance arrival forecasting
– Measurable capacity gains validated through Planned vs. Actual KPIs
– Identified investment priorities — simulation of CAPEX alternatives
Capacity gains without CAPEX escalation — more throughput from the infrastructure already in the ground.
– Modular corridor rollout — deployable network by network, phase by phase
– Integration with Active Train Control — simultaneous live-run management
– Integration with Yard Management System — arrival ETA feeds yard planning
– Configurable objective function — optimize for transit time, fuel, crew, or custom KPIs
– Rapid operational impact — Network Controllers onboarded with structured training
– Scalable adoption model — from a single line to a multi-corridor national network
Rapid value delivery — measurable gains within months of go-live, not years.
Generic traffic management tools show controllers what is happening. ART’s Movement Planner tells them what to do next — and does it automatically.
The optimization engine does not just react to problems. It plans ahead, considers all trains simultaneously, and produces the globally optimal crossing sequence — not the locally convenient one.
That distinction is the difference between a network running at 60% of capacity and one running at 90%.
