Singapore's Mass Rapid Transit system opened in stages between 1987 and 1990, and this coin was issued to mark the network's completion — a project that had been politically contentious during planning, with debates over elevated versus underground routing driving significant cost overruns before construction even began. The MRT was the first metro system in Southeast Asia built from scratch as a unified network rather than an expansion of existing rail infrastructure.
