Shanghai Metro's first 02A05 self-built overhaul train was successfully launched!

The rail transit exhibition learned from Shanghai Metro that at 11:30 on December 14, 2025, the 02101 car slowly drove out of the Chuansha base, and the first 02A05 self-built overhaul train was successfully launched.

1. Whole life ideas Analyze the new model of erection repair

In order to fully grasp the core technology of independent train overhaul and improve the level of independent maintenance, before the start of the project, the backbone of the second maintenance department of Shanghai Metro Vehicle Branch analyzed the characteristics and objectives of the vehicle rack overhaul procedure from the perspective of the whole life cycle, so that the maintenance object is clearer, the method is more reasonable, the cycle is more scientific, and the benefits are more significant. Establish a full-chain management mechanism of "demand list-procurement acceptance-classified storage", accurately map out the needs of various parts and consumables, and complete the inventory, procurement and warehousing of nearly 1,000 materials to ensure timely and efficient material supply

2. Gain growth in the process of practice empowerment

Based on data accumulation, scientific demonstration and practical verification, the second maintenance department will reorganize and optimize the "old rules" and integrate the "rack overhaul manual" close to actual production. During the process, managers established a "weekly meeting" mechanism to solve on-site problems in real time; The leaders of the branch coordinated and guided on the spot, organized communication and coordination, and ensured the steady progress of the overhaul work.

3 The persistence behind the "zero failure" of the train online

As the first train of the 02A05 self-contained overhaul, 02101 carries everyone's efforts and sweat. In order to ensure the stable launch of the train, the team comprehensively carried out commissioning and acceptance work with the goal of "zero-fault online".

The technical team listed nearly 100 debugging projects in the form of a list, constantly testing the core functions to ensure that all performance indicators met the operating standards and helped the train go online safely.
