APITAL deploy and optimize Communication-Based Train Control (CBTC/PTC) system with global signal engineering and data engineering experience to bring the rail industry rapidly into a digital world.
Project Management Service
Apital provides experienced Program Managers, System Integrators, and Test & Commissioning Engineers to assist rail operators in building more advanced digital Signaling and CBTC/PTC systems.
System Design & Engineering
Apital provides CBTC integrators and signaling experts to design & build high-quality signaling and CBTC/PTC system by providing 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
- Working closely with the stakeholders
- Multiple vendor's milestone integration & master schedule control
- Proper/successful project cutover /in-service.
Apital’s experneiced CBTC project managers provide strong project management skills and in-depth CBTC/PTC 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:
- Full knowledge of SSI /Axle Counter System (ACS) /DCS /ZC/ATS/Train system,
- Excellent Interface document control.
- Strong technical coordination among different vendors.
- Proper system configuration management & quality assurance.
Test & Commissioning
Test & Commissioning of CBTC/PTC system is Apital’s powerhouse with a team of experienced CBTC/PTC engineers to
- Generate functional test plan, test cases, test procedures, and test report.
- Review functional test plan, test cases, test procedures, and test report.
- Supervise the inhouse and field test of different subsystem as SSI /Axle Counter system (ACS) / DCS /ATS /ZC/Onboard etc.
Apital team has many years of experience delivering successful test & commissioning around the world.
Track Survey
A railway track survey is critical to know the positioning and status of different track assets such as signals, switches, track circuits, axle counters, transponders, level crossing, communication devices, and other vital rail elements.
- Conduct track survey for vital rail system design and configuration.
- Conduct track survey for vital rail system design and configuration.
- Organize and provide the survey data in the standard or customized format
Apital conducts the track survey through track geometry cars (TGC) or manual carts for CBTC/PTC system design, changes, and other operation and maintenance purposes.
Radio Survey
Radio communication is vital in CBTC/PTC system; the issues of the antennas and other radio communication devices, including their connections, could cause the malfunction of the system.
- Perform radio design survey for CBTC/PTC system.
- Conduct periodic radio roaming test for operation and maintenance.
- Provide the detail radio survey report.
Apital provides radio survey service to rail operators or the radio system designer with independent analysis and report.
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.
- Incorporate the raw data into the new database and configuration.
- Generate new ATS software with new database and configuration.
- Perform full inhouse and field test.
- Release ATS for operation.
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.
- Perform Boolean logic design.
- Conduct the inhouse and field validation test.
- Provide the test result and test report.
ACS Design & Test
Axle Counter System (ACS) is widely used in CBTC/PTC systems as a second detection system. The block system in each Axle evaluation system needs to be carefully designed, programmed, and tested.
- Perform the block design and ACS system logic design.
- Supervise the installation of ACS system, on the track, trackside, and central controller.
- Perform inhouse and field block validation test.
Apital ACS experts provide a full process or part of process service to meet the system requirement or customer needs.
Interconnection Design
CBTC/PTC system involves different types of connection, from the discrete co-axle to optical or ethernet; the interconnection among other systems like SSI/ACS/ZC/Network in CBTC/PTC system could be very complicated.
- Coordinate the requirement from different subsystem provider.
- Perform the conceptual design and installation design.
- Organize the review with different stakeholders to make sure one time right.
Apital long-time CBTC/PTC application design engineers provide end-to-end full-process service or some tasks to fit different customer needs.
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.
- W3@Signal, SSI/ZC Signal Data Analytic System (SDAS)
- W3@Comm, Radio & Communication Monitoring System (RCMS)
- W3@Train, Centralized Train Diagnostic System (CDTS)
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:
Beijing Line 4, China
Hongkong MTR’s first public-private operating line in mainline China.
Flushing (7) Line, New York
The highest-performing operating subway line in MTA
SBL Line, South Korean
The first driverless subway line in South Korea.
