TAIPEI (Taiwan News) —Taipei Rapid Transit Corporation (TRTC) celebrated National Pet Day by operating a special “pet only” MRT carriage on Sunday (April 9).

The “pet only” carriage operated on the Tamsui-Xinyi Line (Red) from Xiangshan to Yuanshan, where pet owners could exit and conveniently attend a nearby pet exhibition at Taipei Expo Park, per UDN.

Taipei Mayor Chiang Wan-an (蔣萬安) rode the special line with pet owners on Sunday. He described it as a trial to test different methods such as fencing to separate dogs and cats, double-layer air filters, and quelling potential animal conflicts with the help of veterinarians, per RTI.

One of Chiang's campaign promises was to make Taipei a more pet-friendly city. Pet owners did not have to pay extra to use the special carriage, but only small or medium-sized cats and dogs were allowed, and it was limited to 30 groups who pre-registered online.

Pets were required to be on leashes, though they could walk around freely with their owners.

TRTC will implement disinfectant procedures before re-opening the carriage to regular service.
