From Darlington Works, Tornado was moved by road on two articulated lorries to the Great Central Railway on 19 August, where she performed mileage accumulation and testing before hauling her first passenger trains. Testing of the On-Train Monitoring Recorder (OTMR), Train Protection & Warning System (TPWS), Automatic Warning System (AWS), and air brakes was also done at the GCR, and are standard for all steam locomotives requiring certification for main line running, with speed and regulator positions tracked by the onboard recording equipment stored under the driver's seat. After three days, Tornado had completed her first non-stop mile run and had hauled empty coaches. Following HM Railway Inspectorate (HMRI), she went on to haul empty trains at speeds up to and with a load of up to around 500 tons. One load test involved a rake of 11 coaches and a Class 45 diesel locomotive, and another saw her achieve 2,000 drawbar horsepower. On 10 September Tornado was officially timed for the first time, hauling 518 tons up the 1-in-176 gradient south from Rothley station.
