Rail Safety

The Trusted Positive Train Control Partner 

LILEE Systems has been the trusted technology partner of North American Positive Train Control (PTC) systems—both I-ETMS and ASCES—for freight, passenger and commuter railways as well as other heavy rail systems such as rapid transit and mine railways.

PTC systems were fully implemented in the end of 2020, and LILEE Systems was recognized by the Federal Railroad Administration (FRA) for facilitating the industry-wide accomplishment.

Solutions for the I-ETMS PTC System

System Management

Monitor, configure and upgrade remote wayside base station and locomotive networks at ease via a unified portal of LILEE’s System Management Gateway (SMG)

Converged Network

Benefit from a unified IP connectivity management solution and enable highly available, cost-effective communications for onboard and back-office applications.


Increase network operation efficiencies by migrating CTC communications to the ITCM infrastructure, standardization and management framework

Solutions for the ASCES PTC System

449 CFR § 236.1033-Compliant Communications Management

Enable FRA-required security and interoperability for all wireless communications between office, wayside, and onboard units

Interoperable Key Management System

Centrally distribute, update, and manage cryptographic-based keys among different railroads to ensure message integrity and authentication with interoperability

Communication Capacity and Redundancy 

Reduce train delays and improve passenger satisfaction by having a cellular backup path in addition to the 220 MHz radio and ensuring availability of train control messages

LILEE SafeRail: AI-Powered PTC 2.0 Technology Solutions

LILEE SafeRail™ combines the latest AI and sensor fusion technology to increase safety for maintenance-of-way (MOW) safety, crossing safety and roadway worker protection. It enables LCCAS (limits compliance and collison avoidance system) and object detection and classification with real-time alerts to MOW vehicles, locomotives and the back office, effectively reducing train-to-vehicle collisions, vehicle-to-vehicle collisions and other on-track and crossing accidents.

Limits Compliance (LCCAS)

Reduce human error and prevent MOW vehicles from violating work zone authority limits or speed limit restrictions through integration with the dispatch/PTC system

Object Detection & Classification

Benefit from advanced AI and sensor fusion technology for reliable object detection, identification and classification for collision avoidance

Vehicle Proximity Alerts

Reduce vehicle-to-vehicle collisions with vehicle proximity alerts even if an
adjacent vehicle is outside the detection range of the MOW vehicle’s cameras and LiDAR

Event-Based Videos & Alerts

Gain complete visibility into your MOW vehicles with surveillance videos of each safety-related event such as speeding, excessive idling and vehicle operating on the wrong track

Foreman Terminal

Allow roadway worker employee-In-Charge (EIC) to visualize track worker location, receive warnings of approaching trains and interact with dispatct to set up work zones

Back-Office Management

Notified via SMS and email alerts and take immediate corrective action when LILEE SafeRail detects an authority limit violation, track authority expiration, overspeed and other safety issues

Safety for Train Operations, MOW Vehicles, Roradway Workers, Crossings and Platforms

LILEE SafeRail short and long range collision avoidance
