Line 1 (Guangzhou Metro)

In 2004, station ventilation and electrical systems started to be updated and platforms strengthened in preparation for retrofitting of platform screen doors in all stations, one of the first PSD retrofit projects in Mainland China.[7] By 2009, all stations on Line 1 where fitted with PSDs.[8]

Retrofitting for PSDs on Line 1

Since Line 1 was put into operation, there have been several incidents of service disruptions due to overhead catenary cable breakages.[9] During that period, Guangzhou Metro experimented rigid catenary installations between Kengkou and Huadiwan stations.[10] Rigid catenary was promoted on all newer lines using overhead electric traction such as Line 2. Since 2007, Guangzhou Metro began converting Line 1's overhead into rigid catenary without shutting down regular service. Instead trains run at a speed limit of 30 km/h (19 mph) when passing through the temporary transition sections.[11][12][13]

In 2011, Line 1 carried out renovation work on the walls of the entire station, removing the original wall tiles and replacing them with gray tiles. Chen Yihua, a middle school student from Guangzhou No. 16 Middle School attracted media attention by opening protesting the rational of the renovation, arguing the new uniform tiles destroy the unique decoration and design features of each Line 1 station. In the end, the project was suspended with only some stations renovated. The rest of the stations remained as is temporarily.[14][15] In 2017, the platform of Line 1 of Guangzhou East Railway Station began to have its wall tiles and false ceiling decorations replaced. However, the replaced tiles and decorations were similar in color to the original. Subsequently, the rest of the underground stations also began to replace wall tiles and hanging decorations accordingly, completing the remaining station renovations using designs as close to the original style as possible.

In June 2016, Guangzhou Metro began to study how to extend the service life of Line 1's A1 series, trains which date from the late 1990s.[16][17] The A1 series was the rolling stock used during the opening of Line 1 and are the oldest in the Guangzhou Metro. The first A1 series trains started the refurbishment 2019–2020.[18] The refurbished trains feature rebuilt interiors, lighting and electrical systems as well as LCD passenger information screens.[19] The newer A3 series where also updated their dot-matrix route maps with full color LCD passenger information screens.

In order to ensure the continuation of reliable daily operations, it was planned to upgrade the entire aging existing signaling system of Line 1. According to the tender information, it will be upgraded to a newer version of the Siemens signaling system.[20] In February 2022, Guangzhou Metro decided to use the holidays in March and April to upgrade the catenary, signaling system and other equipment of Line 1. During the 16-day upgrade and renovation period, the two-way traffic of Line 1 will be closed 1.5 hours earlier.[21]
