The line originally used 4-car trains, making it extremely crowded;[1] although it still carried over 250,000 people daily,[2] peaking at 516,100 on 5 May 2014.

[3] Stations feature electronic passenger information systems, which display estimated train arrival times.

When the second phase of the line opened in 2011, there were only eight trains which were completely unable to meet passenger demand.

[4] English station names were also modified (i.e. 'Futiankouan' changed to 'Futian Checkpoint') for easier recognition, and staff uniform and help desks were also changed to match the styles seen in Hong Kong's MTR.

Passengers with the Hong Kong Octopus card can utilise the kiosk and receive a HK$3 discount on the subsequent trip from Lok Ma Chau on MTR Hong Kong's East Rail line.
