Track hubs have outer lock nuts that are very toothy on their outer face and wheel nuts with built in lock washers... when they are properly torqued they don't move.
Good anti rotation washers are also pretty toothy and will hold a wheel securely without a need for a tug although these can be an extra guarantee against wheel slippage happening and you do only need one tug for the drive side.
