If wheels turn get authority to move train off line at 10mph 5mph over points, move passengers out of that coach
If wheels don’t turn do not move train, report to signaller and control wait for a fitter with a wheel skate to move. Passengers will have to be moved to another train
How do you perform a wheel rotation test
With vehicle at a stand.
Make a mark at the 6 o’clock position on the wheel that has been reported and on the wheels either side using chalk or ballast.
Move the vehicle forward 2-3 foot stop, see if the marks in all the wheels have moved round the same amount.
This will determine if the wheels are turning or not and your next course of action
