What We Do

APITAL deploy and optimize Communication-Based Train Control (CBTC/PTC) system with global signal engineering, data engineering, and management experience to bring the rail industry rapidly into a digital world.

PMC and Construction Management

Apital provides global experienced Program Management, Construction Management, System Integration, and Test & Commissioning in best practice to assist rail operators in building more advanced digital Signaling and CBTC/PTC systems and beyond.

System Engineering & Verification

Apital provides signaling, train control and system verification expert services to design, build and verify high-quality signaling and CBTC/PTC system with in-depth knowledge and best practices during CBTC and signaling system development and deployment.

Revenue Support & Optimization

Apital provides different levels of operation support, from operation supervision to system optimization. Our CBTC/PTC/Signal experts and data scientists perform data analytics for onboard, wayside, and central systems to develop better tools or provide reports to facilitate rail operation and maintenance.

Core Competence

Project Management

The construction project of the CBTC/PTC System is technically and logistically complicated and involves multiple vendors in a complex railway environment, and the program management is critical in terms of

Apital’s experienced project managers and construction managers provide strong project management skills and in-depth CBTC/PTC/Signaling system knowledge to make the projects on time and within budget.

System Integration

CBTC/PTC System Integration is Apital’s key competence to either support rail operators or CBTC system contractors to integrate the system in proper ways; Apital has strong strengths in the following:

Apital’s system integrators have made many CBTC/PTC projects successfully in New York City Transit (NYCT) and beyond.

Test & Commissioning

Test & Commissioning of CBTC/PTC system is Apital’s powerhouse with a team of experienced CBTC/PTC engineers to

Apital team has many years of experience delivering successful test & commissioning around the world.

Track Survey & Data Engineering

A railway track survey is critical to know the positioning and status of different track assets such as tracks, signals, switches, track circuits, axle counters, transponders, level crossing, communication devices, and other vital rail assets.

Track Surveying: Provide a comprehensive track asset survey.

Track Data Engineering: Offer services that involve the data analysis, processing, and management of track asset data including data acquisition, data modeling, and the creation of digital twins of the track infrastructure.

Apital conducts the comprehensive track survey through track geometry cars (TGC) or manual carts, and perform data engineering for signaling/CBTC/PTC system design, changes, and other operation and maintenance purposes, and provide integration to rail operator’s signaling asset management system as needed.

Wireless Environment Survey & Monitoring

Wireless (vital and non-vital) communication is widely used by rail operators, monitoring wireless communication performance, coverage, and interference is very important.

Apital provides survey and monitoring service of wireless communication with world-leading wireless survey and detection solution to deliver the most efficiently and cost-effective wireless survey and coverage gap analysis.

ATS Data Engineering

ATS is critical in CBTC/PTC Automatic Train Control system, whether it is a new or an extension of the CBTC/PTC system to a new area or due to whatever reason with the changes, the proper ATS configuration, HMI, and data need to be updated too.

Apital provide end to end ATS data engineering service

SSI Design & Test

Solid State Interlocking relies on solid state relays with Boolean logic design. Relay logic is a safety-critical task requiring a deep understanding of interlocking logic and careful system design and testing.

Apital provides either the service of the entire process or part of process to fit the customer requirement.

Independent Safety Assessment

The complexity of a complete railway system makes it difficult to accurately analyze and ensure system safety, Independent Safety Assessment (ISA) performs specific assessments or/and audits to establish the maturity and rigor of the safety management process in place by all the actors concerned to ensure a safe implementation of the assessed railway project.

Typical ISA phases:
Concept and system definitions
Systems requirements & apportionment
Preliminary and detailed design
Manufacture & installation
System validation and system acceptance (Inc. handover & trial operations)
Operations and Maintenance (O&M)

Apital provide independent assessments in compliance with global and regional railway safety standards.

BIM & Digital Infrastructure

As the forefront of advancing digital infrastructure, APITAL focuses on Building Information Modeling (BIM) to enable seamless collaboration, precise project management, and intelligent design solutions.
Develop, implement, and enforce BIM standards, guidelines, and workflows
Systems 3D/4D/5D modeling using BIM tools like Revit, ArchiCAD, or Tekla& apportionment
Clash detection, and multi-disciplinary model coordination
Ensure model’s accuracy, geometry, and compliance with project standards
Enhance collaboration, reduce project risks, and improve decision-making

Operation support

Apital OPS Level 1 operation support is to provide experienced CBTC/PTC on-site engineers in the rail control center to support the operational decision.

System Maintenance

Apital OPS Leval 2 operation support is to provide the defined daily or other periodic diagnostic or preventive tests and data analysis to identify and fix the issues during the operation.

System Optimization

Apital OPS Level 3 operation support provides data engineering service. Apital is developing different rail maintenance platforms to optimize system operation and ease system maintenance.

Research & Development

Apital is committed to performing research and development in the rail sector to promote rail digitalization, simplicity, and sustainability.

History & Experience

Apital’s Communication Based Train Control (CBTC) journey started in Shanghai Metro, where the first CBTC system was deployed in 2003; since then, Apital core team members have been working in different CBTC vendors with other CBTC systems in Asia and North America. Together with the industry partners, Apital core members have delivered many successful projects:
