Starting at 3 p.m. on July 3, Chengdu, Sichuan, was hit by a historically rare rainstorm. The meteorological observatory issued a red alert, with over 100 mm of rainfall falling in just three hours in the main urban area. At Qingyang People’s Park Station, rainfall reached 323.7mm, setting a new historical record for a single station in the city centre.

The rain was both intense and concentrated, with a peak hourly rainfall of 102.2mm—breaking previous records. The severity far exceeded the design capacity of Chengdu’s urban drainage system, leading to widespread urban flooding.

At Chengdu East Railway Station, the sudden downpour overwhelmed drainage pipes on the waiting hall roof, causing rainwater to overflow into some waiting areas and creating a "water curtain" effect.

Flooding from outside also caused water to backflow into the arrival level, with water reaching ankle- to calf-height. Passengers had to step on sandbags or wade through the water to move around.

The heavy rain caused delays of over 30 minutes for several trains, though services were not fully suspended. Emergency dispatch protocols were activated at the station.

Railway authorities stated that affected passengers can apply for a full refund within five days of the ticket date via the 12306 platform or station ticket windows.

7月3日15时起，四川成都突遭历史罕见暴雨，气象台发布红色预警，主城区3小时降雨量超100毫米（青羊人民公园站达323.7毫米），创中心城区单站历史极值。

降雨集中且猛烈，小时最大雨强达102.2毫米，刷新历史纪录，暴雨强度远超了成都城市排水系统设计负荷，造成全域内涝。

瞬时暴雨导致成都东站候车室顶棚排水管道排水不及，雨水溢流至部分候车区域，形成“水帘洞”现象。

外部雨水倒灌导致到达层积水，水深没过脚踝甚至小腿，旅客需踩沙袋或涉水通行。

暴雨导致多趟列车晚点超30分钟，但未全面停运，车站启动了应急调度。

铁路部门表示，受影响旅客可在车票日期起5日内通过12306或车站窗口办理全额退票。
