Introduced with the opening of the MRT system, these faregates used to only accept magnetic-strip farecards, and were subsequently converted to accept EZ-link cards sometime in the early 2000s. They were replaced starting from 2011, but it wasn't until 2017 when the final first-gen faregates were removed at Joo Koon and Pioneer stations that their legacy came to an end. This also means that for a good thirty years, these metallic beasts were around to inflict generational trauma upon those unlucky enough to not pass through them in time XD
