MÁV Co. Transport Safety Project (KözOP) Video Track Inspection System (VPR) Installed Vehicle Diagnostic equipment Tamás Both commissioned head of department 7th February 2013

Elements of the present track inspection system Inspection on foot –inspection on foot by patrolmen –Inspection on foot by track-master, chief track-master, section engineer Examinations and measurement in turnouts Line inspection on railway vehicles Inspection of engineering structures ( bridges, culverts, tunnels, etc.) Track geometrical measurements Ultra sonic rail inspection Clearance gauge measurements and examinations 2

VPR structural scheme 3

Main features of video track inspection system (VPR) Able to execute the examinations without disturbing the traffic till the speed of 120 km/h with self-propelled diesel vehicle Measurement by non-contact method, with l aser optic principle, on the base of video records Able to take clear pictures by digital high-speed and low-noise cameras Minim um examination width counted from the track axis 1,75-1,75 m Its two main functions : recording the structural elements of the railway track and panoramic record Able to examine and automatically evaluate m easuring parameters Able to supply local fault list Makes a statistical list for a chosen measuring length 4

Aim of VPR Decreasing of the risk of transport safety and work safety Updating of track inspection activity, track inspection system and procedures, Increasing the objectivity of track inspection examinations, Accurate and traceable documentation of the track state and its change, Accurate identification of the structural elements of te railway track, 5

Advantages of VPR State of the a rt technology Decreases the subjectivity of track inspection Suitable for objective qualification of the structural state Early recognition of rail faults with cracks (Head Check) Suitable for objective examination of high-speed lines Live-labour and cost-efficient solution Risks of traffic safety and work safety decrease Enables the accurate documentation of track state and its change, the more efficient designing of elimination of faults and disturbances Ensures the classification of local faults, and supplies the fault list depending on the speed and size-limit category 6

7 Realisation of VPR 1.) Vehicle _1 1.) Vehicle _2 1.) Vehicle _3 VPR Recording Cars and measuring systems VPR-1 VPR-2 VPR-3

Realisation of VPR Incorporation 3 pcs VPR recording cars into system Within the frames of KÖZOP supporting contract : –Procurement of 3 pcs VPR vehicles –Procurement of 3 pcs VPR measuring systems Tender calling for public procurement of negotiation Tes ting, training of the structural elements of MÁV Co’s lines Further development of VPR measuring system and evaluation software Modification of track inspection regulation (D5), approval by the authority Incorporation VPR into system 8

Characteristics of VPR measuring system 3 pcs VPR measuring systems Contact free examination Its external measuring boxes ( beams ) are located inside the railway clearance gauge. It can examine and supply measuring data at least at 120 km/h s peed range Each record is synchronised with the railway chainage Applies the MÁV database Recording the structural elements of the railway track Panor amic record Determination of the faults of the structural elements Office evaluating and processing system 9

Characteristics of VPR vehicle 3 db d iesel railcars transformed according to the requirements of VPR recording car serves as accommodation for VPR measuring system and staff Ensures connecting points for mounting the VPR measuring system With two engine driver’s cabins 120 km/h allowed and measuring speed Ensures the accommodation of 6 persons Air-conditioned M easuring room, sleeping compartments, dining room, lavatory, technical rooms Supplying the electric energy necessary for the operation of VPR m easuring system 10

Installed vehicle dynamic equipment Hazard point Sensor Hot bearing ( vehicles with hot box ) Hot bearing signal Jammed, stickked brakes ( braked wheels ) Flat wheel D y nami c wheel load meter and wheel flat detector Overloaded vehicles Moved consignment, uneven consignment distribution Broken axles, body-springs Over-reaching the loading gauge Loading gauge checker Wheels under tolerances Wheel flange checker Faulty pantograph Pantograph detector Contact pressure ( between pantograph and contact wire ) 13

Accident occurred due to hot bearing in Italy –June 29th :48 Viareggio (IT): –32 victims, 267 seriously injured people –Due to the breaking of an axle pivot the first 7 wagons of the freight train consists of 14 wagons derailed, from these 5 overturned, one tank ripped, gas (but ane ) spread, then blow up. – Victims emerged from the population, rescue teams found 7 victims under the collapsed h ouses. 14

Necessity and aim of dynamic wheel-load measurement Development of such a diagnostic equipment which registers and filters out the running of vehicles dangerous from transport safety aspect. Operation of the system enhances the safety of railway transport, Decreases significantly the maintenance costs of the railway network and accident damage restoration costs originating from the technical state of the vehicles, or improper loading. Gives information concerning the actual mass of the coach and train- set which is a relevant element of the statement of network access fee (track access fee). 16
