The comfort level of a railway line was recorded for the first time in Turkey

‘Comfort’ was recorded with the measurement performed for the first time in Turkey

For the first time in Turkey, the measurement of the level of comfort of a railway line was carried out on the tramway line “University Yurtlar-Tekkeköy”, where SAMULAŞ A.Ş, a subsidiary of the Metropolitan Municipality of Samsun. provides a passenger transportation service. The railway line was qualified as “comfortable” following the evaluation made in the ISO standards, taking into account the compatibility of the tram wheel with the rail. Samsun Metropolitan Municipality Mayor Mustafa Demir said about 300 million passengers are transported every year with 15 rides per day in the light rail system.
Measurement of the comfort level of a railway line for the first time in Turkey (according to ISO 35-2631 and ISO 1-2631 standards) on the 4 kilometer ‘University Yurtlar-Tekkeköy’ tram line, where the subsidiary of the Samsun Metropolitan Municipality SAMULAŞ A.Ş. provides passenger transport services. ended. The study, which was carried out to determine the comfort of passengers and staff, was carried out by Dr. Sertaç Tuhta of Samsun Ondokuz Mayıs University Civil Engineering Department and Ali Samet Ayvaz, Professor of Machinery Technology Program Rail Systems from Samsun University.


In the study, in which the compatibility of the wheel of the tram and the rail was discussed in various parameters, the effect of the vibrations that occur during the movement of the tram on the passengers, the personnel and the environment was evaluated. . In the study, the comfort level of the railway was measured with special accelerometers mounted on the trams, and the results of the analysis of the railway line were determined as “comfortable”, while they have been reported in ISO standards with state and national software.


Explaining the importance of the work done, SAMULAŞ A.Ş. General Manager Gökhan Beler said that the results of the analysis will be assessed separately for the lines of the 1st floor Gar-OMÜ Rectorate, 2nd floor Gar-Tekkeköy and 3rd floor OMÜ Rectorate-Dortoir, and said: “In total, the raw acceleration values ​​​​of 3 floors are measured with 3-axis accelerometers and software According to the simulation results, an acceleration value of about 0.75 m/s2 was found.This found value revealed that the 35 kilometer Samsun Light Rail System double line is comfortable, thus it was determined that the values ​​of passenger comfort and vibration acceleration of citizens traveling by tram in Samsun are suitable for human health. harmony between the train and the track. It is a record of comfort in the system. Also, looking at the measurement graphs and results in more detail, the regions where the rail-vehicle interaction does not is not up to standard and Points with geometric errors on the line will be evaluated and data that will inform maintenance and repair work will be obtained.


The Mayor of Samsun Metropolitan Municipality, Mustafa Demir, said that around 300 million passengers are transported every year with 15 trips per day in the light rail system and said, “Our two universities are working with SAMULAŞ to determine the system compatibility of the light rail system, which has an important place in urban transportation and whose number of passengers is increasing day by day. a project has been prepared. With the measurements carried out, the compatibility of the tram wheels and rails was evaluated in various parameters and tested if they were in accordance with the standards. The harmony of the system itself is reflected in the comfort of passengers and tram staff. Of course, this result is an indication of the measures we have taken to provide better service to our citizens. It will also highlight the work we will do to ensure the system operates soundly for many years to come. The fact that such an analysis study is carried out in Samsun for the first time in Turkey is also very valuable in terms of the perspective that we draw for the future for the development of such systems.
