4 Generic Product Catalog Introduction Application fields The WIM & WILD is a smart solution entirely based on optical fibre sensors technology, that combines the Weigh In Motion (WIM) functionality with the Wheel Impact Load Detector (WILD). Main Features It was designed to detect automatically the load weight of a moving train, the load imbalances and the overloads. Also, the system is able to monitor the rolling surface of any wheel in transit along the rails, measuring the impact load on the rail of each wheel and detect any type of defect, such as: wheel flats, out of roundness, polygonisation. 4 The WIM & WILD system can be used for various applications and with different aims, such as: Improving safety, Reducing track damage, Improving operational efficiency, Rerouting trains and/or wagons if weight exceeds the load limit of the line, very useful also at national borders or where two independent networks connect. WIM & WILD allows operators to stop the incorrectly loaded cars or to apply a specific speed limit, when overloaded and/or unbalanced cars are detected, therefore preventing axles breaks and potential derailments. The cars and total train weight measurements can be used by the operator to determine the proper routing according to load limits of the rail lines, especially in proximity of bridges or excessive gradients, protecting both tracks and infrastructure from damage. In addition to this, knowing the exact weight of trains helps the operator at national borders or at the exit from yards or mines to perfectly determine the track access charges that apply to the train according to its weight and load transported. Being able to measure the quality of the wheel ensures that vehicles with defected wheels will be repaired before track wear or a possible accident happens. Condition-based maintenance ensures that the reaction time for wheel re-profiling is made shorter and wear of railroad tracks is consequently dramatically reduced. This results in an improved operational efficiency. All Rights Reserved.

5 Weigh In Motion (WIM) & Wheel Impact Load Detector (WILD) System Overview Typical installation layout The system consists of the following components: WIM & WILD Sensors, Sensor Interrogator, Data Processing Unit. Sensors are installed on a track section and paralleldistributed along both rails; they are connected via fibre optic cables to the interrogator placed in the technical room; the data processing unit acquires signals and processes them thereby obtaining the measures. Few kinds of equipments are applied for system, so as to minimize the maintenance and the spare parts. Track requirements The following are points for consideration when selecting a track section for installing the WIM & WILD sensors: the track section (Measure Zone) equipped with the measure points (sensors) shall be straight and as close to horizontal as possible; the train speed shall be higher than 25 km/h for WILD functionality and higher than 2 km/h for WIM functionality; areas of heavy acceleration/braking should be avoided, and possibly the speed of the train must be constant with a maximum variation of 5 % over the total length of the train; sites where trains routinely stop because of signals or stations should be avoided; the sensor-equipped track section as well as the sections set before and after the Measure Zone shall have no rail changes, turn-outs or other track equipment; the sensor-equipped track section as well as the sections set before and after the Measure Zone shall have no defects (e.g.: wooden sleepers, rail joints and weld joints); the ballast in the measure zone shall be uniform and of good quality. Typical system and installation layout Technical room The WIM & WILD system sensors are set in parallel along the two rails. AC/DC converter 230Vac Every WIM & WILD sensor is fitted with fibre optic cables provided with proper connectors in order to implement the connection between two successive sensors. This connection is implemented via an adapter of the same type compatible with connectors. An IP67 box referred to as Disconnection box shall be used to protect fibre optic connectors and adapter.

6 Generic Product Catalog WIM & WILD Sensor The packaged WIM & WILD sensor is a fibre optic strain sensor, packaged into a durable metal housing to improve robustness features, thereby allowing using it in harsh operating environment. The WIM & WILD sensor is mounted between two sleepers, on the underside of the rail, and is anchored to the rail foot by means of clamps. The rail clamps are designed to work with the standard types of the rail, such as UIC60 rail. Advantages The actual mounting takes only few minutes and no special preparation of the rail is required (no rail drilling and no installation platform). The installation doesn t require modification of existing track structure and no specific foundation is needed. For this reasons, the system ensures a fast and easy installation on existing standard rails. The innovative technology and design of the fibre optic sensor give the measure point several advantages: reduced overall dimensions and minimal impact on the track; no modification of the structural or physical characteristics of the rail (no rail drilling and no installation platform required, therefore rail changes are not at all required); ease of installation and removal; no electric/electronic circuits along the rail; fibre optic cables (electric cables are not used); electromagnetic immunity of the equipment; no power supply required, therefore all insulation specifications are met; wide working temperature range ( C); robust construction for operation in harsh conditions. WIM & WILD sensor has been tested and certified in railway applications in compliance with European Norm EN and IS All Rights Reserved.

Measure results and alarms can be used for statistical analysis.

8 Generic Product Catalog Functions The system performs the following main functions: Transit Train Detection; Weight Measure Calculation; Wheel Impact Load Measures and Wheel Defect Detection; Load Imbalance/Overload Detection and Alarm Generation; Train Consist Recognizing. The output measures for each transit are reported in a file, which is stored on disk and is available to operators. Measure results and alarms can be used for statistical analysis. Transit train detection When a train passes in the measure zone, regardless of the running direction, any one sensor detects its transit. The system requires no remote transit announcement sensor. Sensor data storing is incremental and is considered as completed when the last wheel of the train leaves the measure zone. Transited trains are univocally identified by transit date and time, contained in the data file name. Weight measure calculation The system, for each train transited in the Measure Zone, determines the following data: direction of transit; average transit speed; total number of axles; gross weight of wheel; gross weight of axle; gross weight of bogie; gross weight of wagon; total train weight; total train length. System accuracy is 2%. Wheel impact load measures and wheel defect detection The system monitors the entire rolling surface of each wheel and provides the following impact load measurements: average wheel impact (Qstatic); peak wheel impact (Qmax); dynamic load (Qmax Qstatic); dynamic ratio (Qmax/Qstatic); identification of defected wheel. The analysis software identifies a defected wheel and distinguishes the type of defect (wheel flat, out of roundness and polygonisation). The defected wheel is signalled to the operator by the user interface. Train consist recognizing The system recognizes the vehicle types of the train that is transited in the Measure Zone, using the axle distance measurements and comparing them to the structural vehicle information recorded in a database. For this function, the system must be initially configured for the characteristics of the cars that operate on the rail network. The system input data will include car s identity and structural data (number of axles, axle spacing, maximum design axle load, etc). Load imbalance/overload detection and alarm generation Weight measure values are compared to threshold values to check the presence of the following alarms: axle overload; transverse axle imbalance; transverse wagon imbalance; longitudinal wagon imbalance. Alarm thresholds for the different measures can be configured by the operator. For each generated alarm, the following data will be provided: the type (axle overload, transverse axle/ wagon imbalance, longitudinal wagon imbalance); the involved vehicle; the axle / side of the vehicle involved in the alarm; the read value exceeding the threshold values. 8 All Rights Reserved.

9 Weigh In Motion (WIM) & Wheel Impact Load Detector (WILD) Integration RFID WIM & WILD optionally includes a tag reader to enable Automatic Vehicle Identification using RFID tags. The tag information is correlated to the WIM & WILD data output. The antenna reader is interfaced via LAN. T&IMP WIM & WILD system can be integrated to the Train and Infrastructure Monitoring Platform (T&IMP). It sends all the information (measurements, alarms and diagnostics) to the T&IMP via LAN. Auto-Diagnostics The system is equipped with auto-diagnostic tools which routinely check the operating conditions of the individual components of the system and detect automatically the following failures: sensor failure or sensor acquisition chain failure; measure equipment failure. In the event of a failure to certain components, the system will operate in degraded mode, highlighting its condition together with the weight measures of the transited train. Calibration The system is automatically calibrated using vehicles of known weight. Alternatively the average weight of engines passing the site can be used. The system must be re-calibrated yearly, or more often, depending on the specific operating conditions. 9

10 Generic Product Catalog Human Machine Interface (HMI) The processor acts as a web server and, any HMI workstation can access the data stored by the processor with the help of a standard internet browser. This means that a Controller/Operator or Maintainer may access the data via their workstation or laptop if the computer is linked into the rail operator s network (TCP/ IP protocol). The HMI provides the following functionality: Highlight alarms with a visual and acoustic (if required) warning; Display alarm details; Manage alarm recognition; Maintain a log of Operator activities; Store, alarm, vehicle related data and, diagnostic information; Display a list of past and present train movements and consist data; Display the system diagnostic status (for each item of equipment). The system authenticates an operator using Username and Password credentials. The authentication provides different operator profiles, e.g.: view only operator (in this case the operator can only perform alarm recognition) or System Administrator. A nominated operator, (i.e. System Administrator) typically sets the authentication and profile for all other operators Outputs The WIM & WILD system outputs include: transit date and time; running direction; average train speed; total number of axles and wagons; train composition and sequence of wagon types; individual wagon identification (where wagons have ID codes/tags); gross weight of wheel (or axle) and wagon; total train weight; overloaded axles/boogies/wagons; transverse axle imbalance; longitudinal and transverse wagon imbalance; train length; dynamic load; identification of defected wheel; type and size of defect. The WIM & WILD system output data is typically provided to the relevant Train Control Centre for display and storage into database.
