Abstract

One way to reduce energy consumption in electric trains is by using regenerative braking methods. This article aims to present a literature review on the utilization of regenerative braking energy in Electric Multiple Unit (EMU). A descriptive study with a qualitative literature review approach was conducted. The utilization of regenerative braking energy in Electric Multiple Unit (EMU). A total of 10 studies conducted between 2019-2023 were included in this review, out of a total of 1,788 identified titles. These 10 studies met the criteria discussing the utilization of regenerative braking energy in Electric Multiple Unit (EMU) trains. The function of Energy Storage Systems (ESS) or devices as large-capacity energy storage which generates regenerative braking in trains through batteries, flywheels, supercapacitors, and is distributed directly from one train to another to enhance the utilization of electric energy from regenerative braking, including scheduling regulation, reversible substations, and ESS installation, thus capable of saving energy by up to 30%.

Abstract

The study aimed to comprehensively analyze the impact of curves on railway tracks on the wear level of train wheel flanges. The case study focused on the Yogyakarta-Kutoarjo line, which presented a unique track with several curves. Data collection involved meticulous measurements of wheel flange wear on regularly operating trains along the line, along with a thorough analysis of track geometry, train operating speeds, and wheel materials. This quantitative research employed the linear regression method to analyze the data. The findings revealed a notable correlation between wheel flanges A and B's wear levels and curves on the Yogyakarta-Kutoarjo railway line, with 1.036 mm and 1.495 mm of wear on wheels A and B, respectively. The R2 value falling within the range of 0.7521 to 0.9678 indicated a significant influence on wheel flange wear. The study also identified the furthest curved distances, 102,304.80 km for wheel A and 136,857.00 km for wheel B. This research is anticipated to make meaningful contributions to the advancement of railway track and wheel maintenance, ultimately enhancing railway systems' safety and operational efficiency.
