SMRT Active Route Map Information System
The SMRT Active Route Map Information System (stylized as STARiS) is a rail travel information system developed in house by communications engineers from SMRT Corporation for its North–South Line and East–West Line (NSEWL) trains in Singapore. This system was officially announced on 7 November 2008 and was first installed on board a C151 trainset 053/054 for a 2-month trial. This was later extended to other trains from February 2009.
