MTR In-Train TV (Chinese: 港鐵車廂電視) provides Cable TV news and infotainment programmes through LCD displays installed on board Hong Kong's MTR trains.

The entry of C-Stock trains into service in December 2011 also launched the Newsline Express service on Kwun Tong line, the first pre-merger MTR line to be equipped, with 22-inch LCD TVs equipped on those trains.

South Island line trains followed suit in December 2016, at which point the service was renamed as "In-Train TV".

All future train orders, including the R-Train, TML C-Train, and Q-Train, will also be equipped with the service.

The TVs for Newsline Express are sometimes criticized for being too noisy that their broadcasts can even be heard in the quiet car of the train.
