Nunez said initiatives were being undertaken by PTSC to improve the system, which included having the buses equipped with GPS tracking systems, having dedicated lanes on the highway and relocating the garage to Wallerfield. Former works minister Colm Imbert launched the service for the public one year ago. Lalitha Bala-Cetty, assistant deputy general operations (south) said during that year, 500,000 passengers had utilised this service between Port-of-Spain and San Fernando and Port-of-Spain and Sangre Grande.
