Description edit
The exterior appearance of the TML C-train is similar to that of the SP1900, with the most notable differences being located at the cab ends. It is painted in the same livery as the R-trains on the East Rail line, the S-trains on the South Island line, and the Q-trains on the urban lines. The latter two were manufactured by the same company.
The interior layout of the trains has been updated, presenting a refreshed version of the SP1900 design. Notable enhancements include the addition of a new dynamic route map display positioned above the doorways. In terms of seating arrangement, the trains now feature rows of three seats between each doorway, contrasting the four-seat configuration found in the SP1900. At the ends of the carriage, two rows of five seats are still present. Another change is the installation of 22-inch LCD TVs, replacing the 15-inch TVs found in the SP1900. Refurbished SP1900 sets have also undergone this upgrade to the 22-inch TVs. While the electrical equipment and propulsion systems resemble those found in the R-Trains for the East Rail line, there are differences between the two.
The stock bid (number 1141A) was won by China CRRC Changchun Railway Vehicles Corporation Limited in December 2013, at a cost of $1.38 billion Hong Kong Dollars.[1][2] The order was initially for 14 8-car trains, however this was bumped up to 17 8-car trains. This is likely due to the Tuen Mun South extension (still under planning at the time). The first of this train set joined service on the Ma On Shan line in March 2017 and joined service on the West Rail line in March 2020. All 17 trains are running on the whole Tuen Ma line, which fully opened on 27 June 2021.
