Taking a train past the CBTC signalling changeover from the legacy old Westinghouse signalling system. The North South Line is trialing this signalling system for the first time. The changeover takes place at Newton station (17:15 to 23:20).

Under this system, trains travel at a higher speed, the braking profile is smoother, the PSDs will close and open before the train doors do, and most importantly, the minimum distance between trains is greatly reduced and it utilises the moving signal block.
