The Hyundai Rotem EMU (also known as R-Train or 1141B) () is a current model of
heavy rail electric multiple units used on the
Mass Transit Railway in
Hong Kong
Hong Kong ( (US) or (UK); , ), officially the Hong Kong Special Administrative Region of the People's Republic of China (abbr. Hong Kong SAR or HKSAR), is a city and special administrative region of China on the eastern Pearl River Delta i ...
. The 9-car sets are manufactured by
Hyundai Rotem for the
North South Corridor, an extension of the
East Rail line, at a cost of
HK$4 billion. 37 trainsets were ordered in December 2012
and the first delivery took place in 2015, while a further 6 trains were ordered in May 2020.
Originally scheduled to enter service in late-2017 to early-2018, the trains gradually entered service from 6 February 2021. All train sets were put into service in 2022, replacing the
Metro Cammell EMUs and displacing the
SP1900 EMUs to the
Tuen Ma Line.
Formation
The formation ranges from D001/D003 (Trainset 1) to D127/D129 (Trainset 43). Like the previous SP1900s and Metro Cammell EMUs, one car is still reserved for the
first class in each train set. The 9-car formation is shorter than the previous 12-car East Rail Line trains, due to space constraints imposed by new underground platforms on the Sha Tin to Central Link. There are concerns that the new formation may worsen the existing overcrowding problem.
However, the Transport and Housing Bureau and MTRC suggest that the new signaling system and higher train speeds will increase the train frequency from three minutes down to two minutes. It is also estimated that with the completion of the
Sha Tin to Central Link (Tai Wai – Hung Hom section), 20% of the current East Rail line passengers will take the new East West Corridor.
Design and features

The Hyundai Rotem EMU train will be more advanced than the existing trains.
*The exterior of these trains is similar to that of the
C-trains, including the presence of
emergency exit
An emergency exit in a structure is a special exit for emergencies such as a fire: the combined use of regular and special exits allows for faster evacuation, while it also provides an alternative if the route to the regular exit is blocked.

s, the first new trains on the ex-KCR network to be so equipped (though such doorways existed on the pre-refurbished Metro Cammell trains). They are painted in the same
livery as those operating on the
South Island line. The cab ends, though, show some small differences, including a slightly angled front end and modified
headlight cluster.
*Train doors on this stock are more evenly distributed, similar to pre-merger MTR trains. This is especially noticeable in the first class compartment, where the doors are painted yellow to distinguish from standard class. The location of the doors in the first class compartment allow both to be used for normal boarding, which is not possible using the offset arrangement of previous sets.
*Seats near
gangway connections are placed horizontally, making room for standing space.
*Train compartment will be wider than existing trains, increasing capacity. This will also allow for safer boarding and alighting at stations with curved platforms due to a narrower platform gap, such as at
University Station and
Mong Kok East Station.
*All lighting will use eco-friendly
LEDs instead of
incandescent lighting.
*27-inch
LCD
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but in ...
display screen is installed for
MTR In-Train TV.
*Dynamic route maps and improved grab poles that branch out into two in the centre.
