line parameter uses MTR line codes (TKL = Tseung Kwan O, TWL = Tsuen Wan, ISL = Island, KTL = Kwun Tong, EAL = East Rail, TML = Tuen Ma, SIL = South Island, DRL = Disneyland Resort, AEL = Airport Express). Upstream returns sys_time / curr_time in naive HKT; Sugra converts both to UTC. Upstream refresh cadence is 10-30 s; Sugra caches for 5 minutes to match the shortest cache bucket.x-api-key: ********************curl --location '/api/v1/data-gov-hk/mtr/next-train?line=TKL&station=TKO' \
