Dynamic brake must be tested and maintained in operative condition on the number of locomotives required to be equipped with dynamic brake on trains operating, or destined for operation, in the territory filed under subsection 21.2. Locomotives that have not been previously tested cannot be set out and placed on a train requiring use of their dynamic brake feature until they have been tested at a locomotive safety inspection location.

- a gouge or chip in the flange that is more than 1 ½ inches (38.1 mm) in length and ½ inch (12.7 mm) in width;
- a shell of 2 ½ inches (63.5 mm) or more in length or, in the case of multiple shells, 2 inches (50.8 mm) or more in length;
- tread worn hollow 5/16 inch (7.9 mm) or more;
- a crack in the rim, plate or hub;
- a loose wheel;
- the variation in the circumference of wheels may not exceed ¼ " or 2 tapes on the same axle when applied or threaded.
23.2 A railway company shall not place or continue in service a locomotive with a traction motor support bearing that shows evidence of:
- signs of overheating;
- loose or missing bolts;
- oil leaking from reservoir;
- missing or defective reservoir filler cup, or drain plug not properly secured.
23.3 A railway company shall not place or continue in service a locomotive with any of the following journal bearing safety defects:
