The Land Transport Authority (LTA) said the upgrading of the train signalling system will result in shorter waiting times for commuters and a 20 per cent improvement to its existing capacity. Meanwhile, the Circle Line from Marymount Station to Harbourfront is scheduled to open next year. It will provide an alternative route for commuters to the city and will reduce loading along the Toa Payoh to Novena sector by 10 to 15 per cent. First published Sep 2 2010.
