Upgrading the signalling systems is one of the major projects of Rail Gen 2.0. The signalling system functions like our brain by transmitting signals to track and control the speed of the trains to ensure safety.
Working on an operating railway is always challenging. To allow the railway to continue serving the communities during the daytime, the MTR project teams make use of the two hours after the end of the train services to conduct the works and testing. The upgrading of the signalling systems of the East Rail, Tsuen Wan, Island and Kwun Tong Lines is now in full swing. There may be a chance of disruptions to the next day's train service, but we will do our best to minimise the impact on your journeys.
With a new signalling system and upgrades to other facilities, you will be able to enjoy more frequent train services.
A 2-minute online video, featuring the artist, Lai Lok Yi, has been produced to introduce how the MTR Project Teams tackle the midnight challenge. Click here to watch "Working in the Dark".
