Application Effect Evaluation and Countermeasure Analysis of New Catenary Operation Vehicle in High-Speed Railway Operation and Maintenance

With the rapid development of high-speed railway, the traditional catenary operation and maintenance mode can no longer meet the growing demand. In this paper, a new type of overhead contact line vehicle is taken as the research object, and an evaluation system covering three dimensions of operation and maintenance efficiency, cost-effectiveness, safety and technical empowerment is constructed, and it is analyzed with the empirical data of Beijing-Shanghai high-speed railway and other lines. The results show that the new type of overhead contact system operation vehicle has significant advantages in improving operation efficiency, reducing operation and maintenance costs, and enhancing safety, with a comprehensive closeness level of "excellent level". However, there are still bottlenecks in terms of technological adaptability, personnel training, and management mechanisms. To this end, this article proposes countermeasures and suggestions such as optimizing the matching degree of BIM models, upgrading personnel training systems, innovating management mechanisms, strengthening safety risk prevention and control, and continuously optimizing economy. It also proposes a phased implementation path to promote the development of high-speed rail contact network operation and maintenance towards efficiency, intelligence, and sustainability.
