<![CDATA[The Sembawa-Betung double rail track is one of the planned routes of the Trans Sumatra Railways project in Sumatra Island dedicated to passenger and goods transportation. This study aims to analyze the train operating systems of Sembawa - Betung double rail track, that consist of the effective length and the typical layout of rail track, train traffic management, the potential of train travel routes that can be formed, used and conflicted, and the calculation of routes loading level on the train frequency. Based on the analysis conducted using the Conflict Rate method, it can be summarized that the route utilization along with trains frequency served at Sembawa Station, Pangkalan Balai Station and Suak Tapeh Station almost reaches the maximum level of allowable conflict so it may increase the probability of train accidents if there is an additional number of trains served without the construction of additional rail track at the station. On another side, the route utilization, along with the frequency of the trains served at Betung Station, is still far below the maximum limit of allowable conflict, so that there is a possibility to increase the frequency of the trains without the need for additional rail track at the station.]]>

<![CDATA[Inspection lorry very important role in the maintenance of railway infrastructure. Technological modifications in the development of inspection lorry at the Madiun Indonesian Railways Polytechnic are continuing. Development of inspection lorry wheels using composite materials using nylon fiber and hemp fiber as reinforcement and epoxy resin as the matrix. This research was conducted to reduce the load of the third generation inspection lorry which initially used wheels made of nodular cast iron. In designing the wheels of inspection lorry made from composites, this must be taken into account properly so that they do not drop or skid while walking and comply with the main requirements for lorry that are easy to lift and move. The method of making inspection lorry wheels made of composites uses the hand lay-up method. The initial steps taken in this study were designing, determining materials and conducting functional tests. Testing the mechanical properties of the lorry wheel composite materials by diametral tensile strength test with ASTM D695 standard specimens. From the results of the diametral tensile strength test conducted, it was obtained that the specimen had the highest diametral tensile strength value, namely sample 1B of 76.88 MPa and the lowest strength was sample 2B with a tensile strength of 22.73 MPa. The diametral tensile strength value is influenced by the volume of reinforcing fibers, the volume of the binding matrix and the press mold load given to the molding of the composite. Function tests on straight tracks, points, level crossings and curved tracks can run smoothly without any derailments occurring. Noise test wheels made of composites have a lower noise level compared to lorry wheels using nodular cast iron]]>

<![CDATA[Corrosion is the process of material damage that occurs due to the surrounding environment. One way to control corrosion of metal is by coating the surface of the carriage wall consisting of anti-rust paint (epoxy), putty, and color paint. This study aims to determine the effect of coating treatment and the effect of initial treatment on the corrosion rate with the salt mist test. Coating is one method that can inhibit corrosion of metal materials. The salt mist method is used to determine the level of resistance of metal materials to corrosion under certain conditions according to the ASTM B117 standard. Weight loss is one of the methods to determine the corrosion rate by calculating the difference between the weight of the specimen before the test and the specimen after the test. From this test, information will be obtained on the effectiveness of the coating in restraining the corrosion rate. From the test results, it was found that the initial wetblasting treatment with coating and wetblasting without coating had the highest corrosion rates of 0.00054 mmpy and 0.2190 mmpy. While the results of the initial treatment of sandpaper with coating and sandpaper without coating were lower, namely 0.000274 mmpy and 0.00192 mmpy. From the calculation results, it can be concluded that the sandpaper treatment is better than the wetblasting treatment in overcoming the corrosion rate of the galvanized material.]]>

<![CDATA[Railway track is important component in the operational of railway. Railway track structre consist of layers of ballast, sub-ballast, and subgrade. Subgrade located at the bottom of railway track structure thus make this layer hold the whole structure above. In case of damage to the subgrade, then there will be a lot of mismatches in the structure of the overlying layers and reduced stability of the railway track structure. One way to prevent damage on the subgrade is by doing maintenance berfore reaching its service life. This research aims to find out the effect of ballast thickness to subgrade service life. The Analysis was performed numerically using ANSYS 2023 software to determine vertical compressive stress used in the service life calculation. At a ballast thickness of 200 mm the subgrade service life is 43.7 years. Based on PM 60/2012, the minimum ballast thickness is 300 mm. At this thickness, the subgrade service life is 62.7 year, while at the ballast thickness of 500 mm the subgrade service life is up to 98.99 years.]]>

<![CDATA[Railway infrastructure assets are key components in the railway transportation system. Optimal asset management is essential to improve the efficiency and productivity of the railway system, as well as help prevent unnecessary costs in the asset life cycle. Reliability, Availability, Maintainability, and Safety (RAMS) and Life Cycle Cost (LCC) methods can be used in managing railway infrastructure assets. RAMS is a method used to assess the performance of high-complexity systems such as rail infrastructure systems. In contrast, LCC is used to evaluate the overall cost of a system or asset over the life cycle. Integrating RAMS and LCC concepts can help plan railways' design, operation, and maintenance. This integration is very flexible as it can be done from the life cycle's design, operation, and maintenance stages. Research shows that using the integration of RAMS and LCC can lead to better strategic decisions in the life cycle of a railway. In selecting assets to support design and maintenance, for example, there are two high-speed rail double-track alternatives of ballasted and ballastless track, with results showing that ballastless track has higher RAMS performance and lower maintenance cost but higher construction costs, so ballasted track solutions are preferred for short-term construction and the ballastless track is preferred for long-term.]]>
