- GSM-R GSM-R stands for GSM for Railways, a communication system for railway networks utilizing GSM technologies and specific applications for railway operations. It is also the communication standard chosen by EIRENE (European Integrated Railway Radio Enhanced Network) to meet the evolving railway business. It requires Interoperability with national and international railway networks’ communications systems along with Improved operational performance to achieve higher efficiency, safety, and reliability.
- LTE-R/5G-R Long Term Evolution for Railways (LTE-R) is a next-gen communications network dedicated for railway services, enabling high-speed wireless voice and data communications inside trains, from the train to the ground and from train to train. This network supports voice communication among drivers, control center operators, maintenance and other railway staff supporting; push-to-talk group communication, broadcasting, location-dependent addressing and multilevel prioritization; data communication for the train control signaling and other operation and maintenance as well as text messaging during voice communication; multimedia communication for wireless video surveillance, mobile video conference, file sharing, mobile office and passenger infotainment services.
- DWDM Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. The technology creates multiple virtual fibers, thus multiplying the capacity of the physical medium.
- SD-WAN A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE and broadband Internet services – to securely connect users to applications. This dynamic and fast technology is one of Vista’s Key offering.
- IP-MPLS Multiple Protocol Label switching is one of the most accurate, secure and reliable technologies to create real time applications. It is a novel, intricate and costly technology that enables increase of 100 folds in data capacity with myriad uses to its credit.
- TRACK DIAGONOSTICS This technology detects track geometry quality, monitoring, track gauge, Video inspection of Track, twist, longitudinal levels and alignments, Track fastening fittings, alignment/broken sleeper, ballast profile and deficiency, the degree of vegetation with a dedicated staff support .It ensures accurate inspections of every part of the train to promptly detect any safety issues as fire on board or irregular train shape. The system allows to see real time data, to store and localize them through integration with an odometry system. The system also allows off-line data analysis.m

OHE DIAGONOSTICS
This system is capable of measuring and recording main catenary parameters numerically and graphically. It evaluates
- Height of the contact wire from rail surface
- Height of the contact wire from rail surface
- Stagger of the overhead line according to center of the track
- Wear of the contact wire
- Changes in contact wire height
- Disconnection of Catenary wire & Pantograph

WHEEL PROFILE MEASUREMENT
This system is designed to improve the safety of the rolling stock, infrastructure, and the crews and operators that work daily in the railway environment. The system operates automatically when a train is passing and collects data for each wheel of the train.
The system computes the main geometrical parameters of the wheel set in real time and sends an alarm to the supervisor computer if any parameter is outside safety thresholds. All measurements are recorded and accessible for post processing, supplying valuable data for maintenance optimization and reducing costs
The systems is able to evaluate, Flange height ,Flange width, Flange slope and Full wheel profile - HOTBOX DETECTOR Hot boxes or Hot Bearing Detectors are used to measure the temperature of the journal bearings of a train. They typically consist of two infrared eyes on each side of the tracks looking up at the train's bearings. They register the radiation from every journal that passes over them.
- PIPELINE INTRUSION DETECTION SYSTEM PILDS or PIDS is a technology based on Optical Fibre Cable (OFC), that runs along the pipeline, the system is able to detect, locate and even identify any intrusion attempt accurately along the entire monitored length of the pipeline in real-time scenario.This system works on the principle of Distributed Acoustic Sensing (DAS), where acoustic signals generated by intrusion activities are picked up by the optical probe as pulses and sent down the OFC. Detects and locates TPI (Third Party Interference) or physical disturbance activities. It’s a preventative measure. With multi-channel capability, system also has the capability to monitor multiple conveyors simultaneously such that a single system can be programmed to monitor an entire site.
- AXLE COUNTER An axle counter is a system used in railway signaling to detect the clear or occupied status of a section of track between two points. The system generally consists of a wheel sensor (one for each end of the section) and an evaluation unit for counting the axles of the train both into and out of the section. They are often used to replace a track circuit.
- OPH, GPH For Railway Operations and Services, the railways use different types of terminals. These various types of GSM-R terminals have to fulfill not only the GSM-R specific functions like ASCI, but also these thave to work in railway specific environment which requires high speed function, an extended temperature range, shock resistant housing In strong co-operation with the railways MORANE standardized GSM-R handhelds. The following handheld types are based on a 2-Watt standard handheld which covers the whole GSM and GSM-R frequency range and which supports the ASCI features and the EIRENE functions: (a) General Purpose Handheld (GPH): for use in normal environmental conditions, Used by Non-train operation staff like on ground security, Track maintenance staff etc. and (b) Operational Handheld (OPH): Professional application, rough environment, Used by Drivers, Guards and on board staff.
- TUNNEL SOLUTION Railway tunnels vary widely in their construction and layout so it is necessary to have a flexible approach to the design of systems to provide communications within them. Even intermediate and small tunnels also require adequate coverage and present a need to wirelessly connect an existing base site to the tunnel. Tunnel Radio Systems must be able to propagate or transmit a signal with enough strength to be received where needed and the system should have the capability to perform this function with a high degree of reliability.
- CAB RADIOS The GSM-R CAB Radio Systems provides the features of an advanced GSM-R telephone, with all the special railway functions: Advanced SpeechCall Items (ASCI) phase 2+, Emergency Call, eMLPP priority features and Functional Numbering.
