The Changchun EMU or CNR Changchun EMU (also known as C-Train by MTR officially announced) is a train type of the Mass Transit Railway (MTR) in Hong Kong. It is designed and manufactured by Changchun Railway Vehicles, a member of CNR group.

The trains were the first China-made heavy-rail stock in the territory, while past orders came from England, Japan, Europe or South Korea. Designed in 18 months, on 06 December 2010, the first trainset rolled off the production lines at CNR's plant.

The first train was transported to Hong Kong on April 28, 2011. As of October 16, 2011, 4 sets have arrived and are undergoing testing on the Kwun Tong Line, where they will first enter service sometime in November of the same year.

On July 22, 2011, MTR placed an additional order for 12 eight-car trains to supply the West Island Line extension and 10 three car trains for the first phase of the South Island Line.

The first trainset entered service on the Kwun Tong Line on Wednesday evening, December 7, 2011.

On May 29, 2012, the first trainset entered service on the Tsuen Wan Line at 21:54.

On May 13, 2013, the first trainset, A363-A364, entered service on the Tseung Kwan O Line.

The last 8 car train, A393-A394, was handed over on September 5, 2013, and entered service on the Kwun Tong Line shortly after.

Supplement to 22 sets of MTR Metro Cammell EMU(DC)

In this configuration, the pantograph will be on the cab cars (A car), while all three cars will have a motor each (no trailer cars). This train will be of a driverless operation (driver cab replaced by passenger space with a view out the front windows similar to that of an airport people mover). However, it is still possible to operate the train manually if needed. The train will feature a different interior compared to the Kwun Tong Line configuration as well as a different paint scheme and headlight styling. Designed in 16 months, 10 3-car trains are now in-service. These trains are also known as the S-Trains.
