Automated Rolling Stock Control System
LTG Infra is a state-owned railway company of Lithuania, responsible for managing country’s railway infrastructure network, ensuring its safety and development. It is headquartered in country’s capital city of Vilnius. LTG Infra aims to become the most efficient railway infrastructure manager in Central and Eastern Europe. The company strives for the position of a regional leader by modernizing the country railway network in order to maximize the safety of the railway traffic and provide customers with services that meet their needs.
Continuing down the path of modernization, LTG Infra now plans to implement the project “Automated Rolling Stock Control System (RAKS)”, in the scope of which it intends to upgrade the existing rolling stock control equipment by adding new, previously unused solutions and integrate them into a unified system.
Consequently, a market sounding prospectus is aimed at exploring available solutions in the market, as a preliminary step to a public procurement procedure to-be launched in the beginning of the year 2021 by LTG Infra.
LTG Infra operates a number of rolling stock control and monitoring solutions (or subsystems). These subsystems together form the RAKS (Lithuanian abbreviation for automated rolling stock control system) system. Each of these subsystems have a corresponding subsystem code.
The RAKS system, currently operated by LTG Infra, consists of three subsystems:
- Dynamic Weighing (RAKS-1), measuring weigh-in motion of each rolling stock;
- Wheel Impact Load Diagnostics(RAKS-5), detects wheel flats, wheel contact fatigue, out of roundness)
- Hot Box and Hot Wheel Detection(RAKS-4)
Apart from these subsystems, two more subsystems are operated, the control function of which is not integrated with the RAKS system:
- Commercial Inspection and Rail OCR Solution, reads freight wagon numbers and allows visually assess the overall condition of rolling stock;
- Gauge Measurement
The rolling stock monitoring subsystems currently in operation are outdated, inefficient and do not meet the needs of carriers and infrastructure safety requirements. Their level level of interoperability and centralized data management is insufficient.
The vision for the new RAKS system is a unified and geographically optimized solution that is managed centrally. The system will consist of 6 diagnostics subsystems integrated together though a central management software (CMS) solution, ensuring greater reliability of rolling stock control and rail traffic safety. The below summarizes each of the 6 diagnostics subsystems that LTG Infra intends to procure, and a CMS solution. For more details please check Marketing Sounding Prospectus under Documents section below.
The subsystem shall be able to perform dynamic weighing of all rolling stock, both when full and empty. The system shall be able to perform on electrified tracks and withstand electromagnetic forces.
Wheel Impact Load Diagnostics
The Wheel Impact Load system shall detect wheel surface defects (e.g. wheel flats, out of round).
The system will perform pantograph diagnostics of electric traction rolling stock to prevent damage to catenary. It shall provide 3D images of pantograph and its components, as well as visual footage of damaged area.
Commercial Inspection and Rail OCL Solution
The system will perform inspection of rolling stock and identify rolling stock as well as transported container numbers. It shall provide video footage of rolling stock for effective monitoring of the condition of wagons and containers. It shall also provide rolling stock and container ID numbers readings.
Hot Box and Hot Wheel Detection
The system will monitor temperature measures of axle boxes, locked wheels and rails. Sensors shall be installed in or on special metal railroad ties and monitor temperature for each axle box from both sides. Sensors shall also be able to differentiate between cassette and roller axle box bearings.
The system shall generate 3D images of rolling stock gauge violations. It shall have two alarm levels for structure gauge violations (minimum clearance outline) and load gauge violations. System performance shall be independent of environment or weather conditions.
Central Management Software (CMS)
The central management software (CMS) will integrate all 6 rolling stock control solutions. It will intercept their readings and alarm notifications. Its secondary functionality will be monitoring the condition of the diagnostics equipment itself. It shall provide users with display of the system map and technical condition of the monitoring checkpoints.
- It is planned to announce the public procurement in the beginning of 2021;
- The company intends to run a single tender, divided into multiple lots (parts of contract) for different automated rolling stock control subsystems and a central management software (CMS) solution to integrate them;
- The procurement of dynamic weighing and wheel impact load subsystems will be combined into a single lot;
- Suppliers may bid (individually or through a joint venture) for the whole contract (all 6 lots – the whole solution), a combination of several lots, or a single lot (partial solutions). In any way, each lot will have a separate contract, thus, when bidding for the whole solution or any multiple lots, it is required that combinations of lots would be priced separately for different parts of the tender;
- LTG Infra intends to announce the contract (or parts of the contract) award by August 2021.
