Mandatory data collection at EU level is based on legal act, the Regulation EU 2018/643 and covers goods and passengers.
Data is collected as following:

• Annex I (annual data) –goods transport ,
• Annex II (annual data)–passenger transport,
• Annex III – (quarterly data) goods and passengers,
• Annex IV and V( data every five years) regional statistics on goods and passengers and rail network and
• Annex VIII (annual data) goods and passengers transport for small undertakings.

Goods transported by rail are classified according to the 20 divisions of goods following the 'Standard Goods Classification for Transport Statistics 2007’ with effect from reference year 2008.

The codes of regions used in the region-to-region statistics are indicated in Regulation (EC) 1059/2003 of the European Parliament and of the Council.

Railway undertakings providing transport of passengers or goods.

The main concepts used in rail domain are:

Rail passenger means any person, excluding members of the train crew, who makes a trip by rail. For accident statistics, passengers trying to embark/disembark onto/from a moving train are included.
Passenger-km means the unit of measure representing the transport of one passenger by rail over a distance of one kilometer. Only the distance on the national territory of the reporting country shall be taken into account.
Weight means the quantity of goods in tonnestones (1 000 kilograms). The weight to be taken into consideration includes, in addition to the weight of the goods transported, the weight of packaging and the tare weight of containers, swap bodies, pallets as well as road vehicles transported by rail in the course of combined transport operations. If the goods are transported using the services of more than one railway undertaking, when possible the weight of goods shall not be counted more than once.
Tonne-km means the unit of measure of goods transport which represents the transport of one tonne (1 000 kilograms) of goods by rail over a distance of one kilometer. Only the distance on the national territory of the reporting country shall be taken into account.
Train means one or more railway vehicles hauled by one or more locomotives or railcars, or one railcar travelling alone, running under a given number or specific designation from an initial fixed point to a terminal fixed point. A light engine, that is to say, a locomotive travelling on its own, is not considered to be a train.
Train-km means the unit of measure representing the movement of a train over one kilometre. The distance used is the distance actually run, if available, otherwise the standard network distance between the origin and destination shall be used. Only the distance on the national territory of the reporting country shall be taken into account.

Statistical units for rail transport statistics are all railway stations.

Data on passenger and freight transport are collected from the railway undertakings operating at national territory within thresholds mentioned in the rail regulation.
Data on traffic are collected from infrastructure managers and railway undertakings.

Operational railway network on national territory.

Data on passengers and goods are covered from 2004 onwards.

Not applicable.

The volume and performance of rail freight traffic are measured in tonnes (mass) and tonne-kilometres. Passenger transport by rail is measured in the number of passengers and in passenger-kilometres. Information on the number of train kilometres is also available.
Traffic flows on the rail network are measured in number of trains - passenger, freight and others (optional)

The tables consist mostly of annual data. There are some tables providing quarterly and quinquennial (every five years) data.

According to the Rail regulation (EU) 2018/643 data is collected as following: Annual data
– Annex I –goods transport collected for a reference period of one year with a deadline for data transmission as 5 months after the reference periodreference period,
– Annex II –passenger transport, yearly data with eight months deadline after the end of reference period
– Annex III – quarterly data for goods and passengers with a deadline of three months after the end of the reference period,
– Annex IV and V data every five years on regional statistics on goods and passengers and rail network with deadline of 12 respectively 18 months after the end of reference period and
– Annex VIII goods and passengers transport for small undertakings with 5 respectively 8 months deadline after the end of reference period.

There are two data sources for Turkish railway transport statistics. Data related to railway infrastructure is compiled based on administrative records of General Directorate of Turkish State Railways (TCDD), while the other data is compiled by Ministry of Transport and Infrastructure (MoTi) Directorate General for Regulation of Transport Services.

TCDD Corporate Resource Management Information system project studies are carried out in order to manage and execute the resources and activities of the organization effectively. 

Corporate Resource Management Information system project, reporting and evaluation of statistics can be made through administrative records created on the web.

Thanks to detailed publication regarding Railway statistics on https://www.tcdd.gov.tr/en/, user needs are widely met. National and international questionaires are almost fully filled.

User satisfaction surveys are conducted within the scope of the annual strategic plan from TCDD and MoTi.

Railway statistics is dissaminated at t+6 month by the Turkish State Railways unde the Official Statistic Programme. For the Annex the time is t+5.

Much attention is paid to this issue.

Railway statistics cover whole country and available in NUTS level, so it is coherent in terms of geographical aspect.  

There are two data sources for Turkish railway transport statistics. Data related to railway infrastructure is compiled based on administrative records of General Directorate of Turkish State Railways, while the other data is compiled by Ministry of Transport and Infrastructure Directorate General for Regulation of Transport Services.

In consultation with relevant institutions, Turkstat revised the Annex E data for 2011-2023 and Annex C. For the reference years 2011-2023, stakeholder institutions managed to distingusih traffic of light rail system (banlieu) transportation from the total traffic.

Number of passengers in national transportation were revised by excluding the traffic in metro, tram and light rail systems.

Explanations about data for Marmaray, Başkentray, İzban and Gaziray are listed below; 

• Since the reference year 2011, İzmir Suburban System (İZBAN) data is excluded in train-km, passenger-km and passenger figures of Annex E and Annex C data.
• Since the reference year 2013, MARMARAY (Istanbul) data is excluded in passenger and passenger-km figures of Annex E and Annex C data.
• Since the reference year 2018, BAŞKENTRAY (Ankara) data is excluded in passenger and passenger-km figures of Annex E and Annex C data.
• Since the reference year 2022, GAZİRAY (Gaziantep) data is excluded in passenger and passenger-km figures of Annex E and Annex C data.

After this revision, the break in the series that occurred in 2011 was revised. After 2023, metro, tram, light rail and banlieu data will not be included in national transportation data.

Mirror check results are taken into consideration and shared with MoTi and Turkish State Railways. There is no major inconsistency.

Railway statistics are compared internally. It is coherent.

With the begining of liberalization of the railway sector in Turkey in freight transport, railway companies are no longer willing to share detailed statistics with Turkish State Railways.

This situation is evaluated as a big problem in compliation of railway statistics with the current detail.

TCDD Transportation Inc. carries passenger transportation, OMSAN Logistics and KORFEZ logistics carries freight transportation in railways.

For the statistics produced in the scope of rail data, revision is not foreseen in the current year. Any future revision shall be publicly announced.

A revision study was conducted in March and April 2024 and passenger numbers were updated for the years 2011-2023.

When needed, data revision is performed by Ministry of Transport and Infrastructure (MoTi) Directorate General for Regulation of Transport Services. Turkstat monitors revisions.

A revision work was done with MoTi after the official statistics program meeting. In consultation with relevant institutions, in 2023 and 2024 we revised the Annex E data for 2011-2023 and also Annec C.
