PT KAI (Persero) tidak pernah berhenti mentransformasikan dirinya. Transformasinya sangat diperhatikan ketika PT KAI (Persero) berada di bawah wewenang Jonan Ignasius. Edi Sukmoro kemudian melanjutkan transformasi. Beberapa peningkatan kualitas layanan di setiap stasiun kereta api membutuhkan apresiasi dari berbagai aspek. Saat ini, keamanan ditingkatkan, tiket lebih mudah didapat, dan perjalanan lebih nyaman karena kereta disediakan oleh AC. Namun, mengingat biaya yang diperlukan, pemasangan AC di semua gerbong kelas bisnis dan ekonomi tidak menerapkan AC sentral tetapi membagi AC seperti yang diterapkan di rumah atau kantor. Penelitian ini untuk mengetahui pengkondisian udara yang paling efisien dalam mengonsumsi energi dalam kereta api, oleh karena itu, dilakukan. Studi ini juga menyelidiki pendingin udara yang paling efektif dalam pendinginan. Hasil penelitian menunjukkan bahwa efisiensi energi pendingin udara split lebih rendah daripada pendingin udara sentral. Mengenai kapasitas pendinginan, AC sentral diproduksi oleh PT INKA yang memiliki kapasitas pendinginan lebih tinggi daripada AC split.

One example of technological developments in signaling systems in Indonesia is the use of detection facilities on rail lines. A detector is a device that functions to detect the presence or absence of train facilities on the railroad track. Detection equipment is divided into two types, namely axle counter and track circuit. Track circuit detects the presence of trains on the rails, while the axle counter functions to count train axles. This study aims to find a detection system for facilities that is suitable and in accordance with the conditions of the Surabaya-Madiun cross and find out the characteristics for the installation of detection facilities in accordance with the pathway. To find out the appropriate facility system, the two tools are analyzed in terms of system reliability, environmental influences, advantages and disadvantages, disruptions, maintenance, and operations. The results showed that an effective and efficient way of detecting traffic in Surabaya - Madiun was the detection of a double head axle counter facility. This tool is very suitable to be installed in the emplacement.

PT KAI (Persero) has never stopped transforming itself. His transformation was highly considered when PT KAI (Persero) was under the authority of Jonan Ignasius. Edi Sukmoro then continued the transformation. Some improvements in service quality at each train station require appreciation from various aspects. At present, security is improved, tickets are easier to obtain, and travel is more convenient because trains are provided by AC. However, given the costs involved, installation of air conditioners in all business and economy class cars does not apply central air conditioning but divides air conditioning as applied in the home or office. This research is to find out the most efficient air conditioning in consuming energy in trains, therefore, it is conducted. This study also investigates the most effective air conditioning in cooling. The results showed that the energy efficiency of split air coolers was lower than central air coolers. Regarding cooling capacity, central AC is produced by PT INKA which has a higher cooling capacity than split AC.

PT Kereta Api Indonesia (KAI) during 2019 and 2018 calculated that there had been 655 accidents at level rail crossings. Accidents often occur in high traffic areas such as the Telecommunication Signal Resort 4.6 SMT. So the researchers conducted research in order to find out the performance of the railway operating facilities under the auspices of the Telecommunication Signal Resort 4.6 SMT as well as public perceptions of its performance. Researchers used a sound level meter to measure the loudness level of the level rail crossings siren sound at the research location. Furthermore, it is compared with the standards stipulated in the Minister of Transportation Regulation Number 44 of 2018. Then tested using Anova to find out whether the population mean will be of the same value using data from each population. Furthermore, an unstructured interview was conducted to hear the perceptions of road users on the performance of the operational facilities at level rail crossings which became the research object. The results showed that the five level rail crossings which were the object of the study had the loudness level of the siren sound below the set standard. In contrast, flat cross lights perform well. Meanwhile, the public perception of the operational facilities at level rail crossings is that they are functioning well. Keywords: level rail crossing, operating facility, railway
