Agenda • Definition of Train and Path • Main objects and attributes • Life cycle • Train modified in one network only • Numbers • Data model
Existingdefinitions : Train, Path (1/3) • Single European Railway Area (directive 2012/34) • ‘international freight service’means a transport service where the train crosses at least one border of a Member State; the train may be joined and/or split and the different sections may have different origins and destinations, provided that all wagons cross at least one border • ‘international passenger service’means a passenger service where the train crosses at least one border of a Member State and where the principal purpose of the service is to carry passengers between stations located in different Member States; the train may be joined and/or split, and the different sections may have different origins and destinations, provided that all carriages cross at least one border • ‘urban and suburban services’means transport services whose principal purpose is to meet the transport needs of an urban centre or conurbation, including a cross- border conurbation, together with transport needs between such a centre or conurbation and surrounding areas • ‘regional services’means transport services whose principal purpose is to meet the transport needs of a region, including a cross-border region • ‘train path’means the infrastructure capacity needed to run a train between two places over a given period
Existingdefinitions : Train, Path (2/3) • OPE TSI (regulation 2012/757) • Train : A train is defined as (a) traction unit(s) with or without coupled railway vehicles with train data available operating between two or more defined points • Rolling Stock LOC&PAS TSI (regulation 1302/2014) • A ‘train’ is an operational formation consisting of one or more units • TAF &TAP TSIs (regulations 1305/2014 & 454/2011) • ‘path’means the infrastructure capacity needed to run a train between two places over a given period (route defined in time and space) • ‘path assembly’ : Joining up of individual train paths to extend path in terms of time and space • ‘route’ : The geographical way to be taken from a starting point to a point of destination • ‘train path’ : Train route defined in time and space • ‘train path/slot’ : A definition of a train's route in terms of time and the locations (marker points) at which it will originate and terminate along with details of those locations en-route at which it will either pass or call. The detail might also include any activities that the train will perform en-route for example train crew, locomotive or other consist changes
Existingdefinitions : Train, Path (3/3) • Draft CUI Uniform Rules (OTIF) • ‘international railway traffic’ means traffic which requires the use of an international train path or several successive national train paths situated in at least two States and coordinated by the infrastructure managers concerned • The definitions of Train and Path are various • The wordServiceisusedaccording to the client point of view • A commondefinition of Train and Path shouldbeagreed by the differentactors • This definitionshouldreflect the differentunderstandings
Proposal of definition : Train • According to the context, a ‘train’ could be : • ‘production train’ • defined as a journey between an origin and a destination with a timetable and a given calendar • to be implemented, a ‘production train’ needs a path, a set of vehicles including tractive vehicles (cf. ‘physical train’) and human resources (driver, conductor, etc.) • the composition of a ‘production train’ can vary during the journey and can carry one or several ‘commercial train(s)’ • ‘commercial train’ • defined as a seamless offer of transport for the passengers or freight loads between origin and destination of the ‘commercial train’, including intermediate stops • the ‘commercial train’ receives a number used by the client or loader to find information about the journey • ‘physical train’ • defined as an operational formation consisting of one or more units (cf. definition of ‘train’ in LOC&PAS TSI) • defined by the set of European Vehicle Numbers (EVNs) of each vehicle • it’s the train running on a track The concept of ‘physicaltrain’ is not very relevant for timetablingconcerns
Proposal of definition : Path • ‘Path’ • ‘path’means the infrastructure capacity needed to run a train between two locations over a given period (route defined in time and space) • a ‘path’ is designed by the infrastructure manager (or the allocation body) usually on national level • a ‘path’ can be an assembly of other paths to reflect the complete journey of a train, we speak then of ‘full assembled path’ • a ‘path’ is designed : • on request of a railway undertaking (or an applicant) • or directly by the infrastructure manager without request in order to structure the capacity of the network (‘pre-arranged path’)

What are the main objects and attributes for planning and operation ? PLANNED TRAIN NUMBER(PTN) is the "short number" usedby RU to identify the train during RU harmonisation (in PCS, fieldcurrentlynamed "International Train Number"). PATHis the space-time allocatedby IM to RU.Identified by PAIDdecided by the IM 5 3 6 Köln 1 COMMERCIAL TRAIN NUMBER(CTN) is the numberused for passengersinformation (e.g. on the reservation ticket, display in stations).The CTN isallocated by the RU and usedby the RU and the SM (Station Manager) Amsterdam TRAINis the "move offer"foreseen by RU. Identified by TRIDallocatedby the RU at the beginning of the path allocation INFRASTRUCTURE TRAIN NUMBER(ITN) is the "short number" usedby IM to identify the national path and usually the assembledpathaccording to UIC leaflets 419-1/2 Bruxelles 7 Object Paris Time PATH REQUESTis a request by RU to IM to receivea pathto operate the train.Identified by PRIDallocatedby the RU Attribute 2 CASE REFERENCEis a workflow document used for one pathrequest or a set of pathrequestsgathered for organisationalreasons.Identified by CRIDallocatedby the RU (or the IM for internalpurposes) OPERATIONAL TRAIN NUMBER(OTN) is the "short number" used by IM and RU in dailyoperation (e.g. display in signalling box, communication signallingbox/train).Allocated by the IM, itisusuallyequal to ITN and canbechanged in case of event in operation 4 8
Description of the objects Objectsand Identifiers - Overview • Four objects are definedcurrently • Train ("owned" by the RailwayApplicant [RA]) • Path Request("owned" by the RA) • Path("owned" by the IM) • Case Reference cf.Dossier("owned" by the RA, IM, otheractors) • Theseobjects are not explicitelydefinedin the TAP/TAF data model (xsd) but implicitelydefined in the messages • The data model willbeproposed at the end of the presentation TRID, PRID, PAID, CRID have a common structure : Planning (withcalendar/regime) : 24 AN Operation (withday of running) : 32 AN

Numbers(check alignmentwithfor FTE WG) • PTN (Planned Train Number) • "Short number" used by the RUsto identify the train during RU harmonisation between the planners • Allocated by the Lead RU, usually by agreement with the otherRUsinvolved in the harmonisation • Unicityisrequired in the scope of RU harmonisation • Usually the PTN is the ITN of the full assembled path • If several ITNs are used for the full assembled path, the PTN is usually the “main” ITN (longest journey, nb of running days, etc.) • The ITN can be changed during the planning process • Could be alphanumeric depending on agreements between RUs • As one CASE REFERENCE can concern MAIN and SUB, the PTN is an attribute of the CASE REFERENCE grouping MAIN and SUB • As one PATH REQUEST can lead to several PATHS, these objects are grouped in the CASE REFERENCE with the PTN as attribute • The PTN could also be an attribute of the TrainInformationSection, tbc
Numbers • CTN (Commercial Train Number) • "Short number" usedfor passengers information (e.g. on the reservation ticket, display in stations, etc.) • The CTN isallocatedby agreement between the involvedRUs • The CTN isused by the RUs (retail, ticketing, passengers information) and the Station Managers (information in stations) • The CTN islinked to a set of vehicles on the samejourneywith the sameorigin and destination • A "Production Train" can carry one or several CTN(s) • Unicityisrequired in the scope of retail and passengers information • Could be alphanumeric depending on agreements between RUs
Numbers • ITN (Infrastructure Train Number) • "Short number" used by the IM(s) to identify the national pathand/or the full assembledpathaccording • ITN is a numbercompliantwith: • UIC leaflets 419-1/2 for international trains • National train numberingscheme for domestic trains • Unicityisrequired in the scope of (future) operation • Allocated by the Coordinator IM (international trains) or the IM (domestic trains) during the planning phase • The ITN can change along the journey depending on international or national rules • The RUs can request a “preferred ITN” usually by pre-agreement with the IMs • Is only numerical due to technical constraints with GSM-R and ETCS
Numbers • OTN (Operational Train Number) • "Short number" usedby the IMsand RUsin dailyoperation (e.g. display in signalling box, communication signallingbox/train, etc.) • OTN is a numbercompliantwith: • UIC leaflets 419-1/2 for international trains • National train numberingscheme for domestic trains • Unicityisrequired in the scope of operation • Equal to the ITN whenoperationtakes place as planned • The OTN can change in case of operationalevents, depending on international or national rules • Is only numerical due to technical constraints with GSM-R and ETCS
