Operating speed of Big Grizzly Mountain Runaway Mine Cars at Hong Kong Disneyland, Grizzly Gulch. RCDB says 34.8 mph and elements of two chain lifts plus a LIM launch. Coasterpedia says 34.8 mph (56 km/h), which is 34.8 mph, and the same LIM launch. Wikipedia says 45 mph (72 km/h), which does not convert. The figure is RCDB's 34.8 mph, qualifier estimated, because Wikipedia disagrees. No 0-to-speed clock is published. The launch time is 34.8 mph.

  1. Where the speed comes from

    RCDB says 34.8 mph and a LIM launch between chain lifts. Coasterpedia says 34.8 mph (56 km/h), which is the same 34.8 mph. Wikipedia says 44.7 mph (72 km/h), about 45 mph, which does not match.

  2. The number on the row

    RCDB is the coaster rank. The Wikipedia disagreement makes the row an estimate. No 0-to-speed clock is published, so the launch list uses 34.8 mph.
