On the afternoon of 16 October, a fault in the Zhenjiang section of the Shanghai-Nanjing express railway caused delays to more than 10 train services and the cancellation of four Shanghai-bound services. This was the second major delay since the line went to operation on 1 July. According to passengers, one of the trains arrived in Shanghai more than two hours late.

Refunds were available for the cancelled services, but no compensation was offered to passengers stuck on the delayed trains. Many people using the express service are business travellers with appointments to make. Some leading transport lawyers are calling for legislation to force service providers to provide alternative means of reaching destinations.
