Abstract

The flange is an essential part of the wheel that serves to guide the wheel as it passes through curves. If worn, the flange can cause derailments and reduce the wheel’s service life. In LRT Jabodebek, flange wear is relatively high, requiring re-profiling (turning). This study aims to identify the effects of flange wear and explore methods to mitigate it. The analysis method uses a fishbone diagram to identify the root causes. The results show that flange wear is caused by the high number of curves with a radius less than 150 meters, which do not fully comply with existing maintenance standards. Reduced surface hardness due to repeated reprofiling and lack of thorough inspection during maintenance also contributes. Efforts to reduce wear include re-evaluating curves with small radii, adjusting rail widening and elevation, using coolant during turning, and conducting more thorough visual and manual inspections. Additionally, applying lubricant to the flange and rail curves can help minimize wear.

Abstract

An innovative solution for low-emission and environmentally friendly freight transport is the Rollende Landstraße (ROLA) train. Research at the Indonesian Railway Polytechnic (PPI) in Madiun conducted dynamic simulations to analyze safe operating speeds when crossing minimum curved tracks with a radius of 42 meters to prevent derailment. The simulation results show that the optimal speed limit for ROLA transport is 14 km/h for fully loaded trucks, 17 km/h for half-loaded trucks, and 19 km/h for unloaded trucks. This speed must be maintained constantly when passing through curves to ensure safety and comfort.

Abstract

Corrosion is one of the main problems that can reduce the quality and service life of steel materials in the railway industry, especially on train roofs made of SS400 mild steel. This study aims to examine the effectiveness of adding natural inhibitors from corn cob ash to epoxy primer paint in inhibiting the rate of corrosion and increasing the adhesive strength of the paint. The inhibitor was made through a process of extracting silica from corn cob ash and mixing it into the primer paint at various concentrations. Fourier Transform Infra Red (FTIR) testing was used to identify the silica content in the inhibitor, while testing was carried out on the adhesive strength using an adhesion tester and the corrosion rate using the weight loss test method in HNO₃ solution. The results showed that the addition of corn cob ash inhibitor formed a protective layer on the metal surface, improved paint adhesion, and significantly reduced the corrosion rate. This study demonstrates that the use of agricultural waste such as corn cobs as a natural inhibitor is an innovative, economical, and environmentally friendly solution for controlling corrosion in steel materials in the railway industry.

Abstract

The locomotive driver's cabin receives high thermal loads due to solar radiation through the large glass field and heat from the diesel engine room, thus requiring an air conditioning system with the right capacity for the comfort and safety of the operator. This study calculated the cooling load of the CC 206 Locomotive cab and compared it with the installed air conditioning capacity. Calculation using the CLTD/SCL approach heat load method (Hidayat & Restu, 2017; ASHRAE; SNI 03-6572-2001) with data on the structure and material of the casing from the technical data of the facility, at the design conditions of cabin temperature 25.5 °C, outside temperature 32.78 °C, and engine room temperature 40 °C.  The conductance value (U) of each element is calculated from the arrangement of the material layers. The results showed a total cooling load of ± 2,585 W (≈ 2,222 kcal/h; ≈ 0.73 TR), dominated by solar radiation through glass and ventilation latent loads. The capacity of the TERMORAIL TRC-8000 installed air conditioner is 8,000 kcal/hour, approximately 3.6 times the calculated load of tune; The margin is functional for pull-downs and extreme conditions. It was concluded that the installed air conditioning unit is very adequate in a tune-like manner, with the potential for optimization in glass shading and compressor capacity regulation.

Abstract

Friction stir welding (FSW) is a solid-state joining process that is increasingly used to fabricate aluminum railway carbodies. This study examined the effect of tool pin diameter on the tensile properties of FSW joints in 6 mm thick AA6061-T6 aluminum plates. High-speed steel tools with a 13 mm flat shoulder and straight cylindrical pins of 3, 4, and 5 mm diameter were fabricated by turning, and butt joints were welded on a conventional milling machine at a rotational speed of 1130 rpm, a traverse speed of 20 mm/min, and a tilt angle of 3°. Three joints were produced for each pin diameter (n = 3), and one transverse tensile specimen was tested from each joint. Results are reported as mean ± standard deviation and were analyzed using one-way ANOVA, the Kruskal–Wallis test, and Spearman’s rank correlation. The mean tensile strength decreased from 210.06 ± 5.87 MPa with the 3 mm pin to 190.96 ± 26.57 MPa and 146.36 ± 62.26 MPa with the 4 and 5 mm pins, respectively, while the scatter increased with pin diameter. Owing to the small sample size and large scatter, the differences among group means were not statistically significant (p = 0.206); however, pin diameter was negatively correlated with tensile strength (ρ = −0.74, p = 0.023). Visual inspection revealed less weld flash with the 3 mm pin, consistent with the smaller volume of material displaced by the pin. Within the tested range, the 3 mm pin provided the highest and most consistent tensile strength.

Abstract

Excessive smoke from diesel locomotives signals incomplete combustion and degrades engine performance and air quality. This exploratory mixed-methods study examined factors associated with smoke level in CC206 locomotives running B40 biodiesel at a depot in Yogyakarta, Indonesia, using records from January to June 2026, and ranked maintenance risks. Twenty-four fault-history records from 21 locomotives (injector age, fuel pressure, combustion chamber temperature, visually rated smoke level) were analyzed with ordinal logistic regression and separation-robust sensitivity analyses; technician interviews were analyzed with content analysis, root cause analysis (RCA), and failure mode and effect analysis (FMEA). Combustion chamber temperature was associated with smoke level (B = 0.069, p = .022), but every level-9 record exceeded 740 °C and every other record was at or below 640 °C, so the estimate is unstable and implies neither a gradient nor causation. Injector age and fuel pressure showed no detectable association. FMEA ranked injector damage (RPN = 360), non-optimal maintenance scheduling (280), and clogged fuel filters (210) highest. The findings are hypothesis-generating and require verification with larger, instrumented data that include normally operating locomotives.

Abstract

The bogie bolster is a critical component that transfers vertical and lateral loads between the carbody and the bogie frame. This study evaluated the structural safety of a reengineered TB1014 bogie bolster in which the coil-spring secondary suspension was replaced with an air spring, and compared it with the original coil-spring bolster under identical conditions. A three-dimensional finite element model, built in SolidWorks and analyzed in Ansys Workbench 2024, was subjected to the static overload cases of UIC Code 515-4, with the vertical overload applied at the center pivot and side bearers simultaneously as a conservative envelope. The model was verified through a mesh-convergence study and reaction-force equilibrium; it was not physically validated. Under vertical loading, the air-spring bolster produced a maximum von Mises stress of 161.56 MPa and a deflection of 0.699 mm, versus 167.08 MPa and 1.030 mm for the coil-spring design. Under combined transverse-and-vertical loading, the values were 142.56 MPa and 0.659 mm versus 168.06 MPa and 1.032 mm. Both designs remained below the 245 MPa yield strength of SS400, with factors of safety of 1.52–1.72 and 1.46–1.47, respectively. Within a linear static analysis, the reengineered bolster satisfies the static strength requirement with a higher margin.
