Table of Contents


The official version of the CROR , in its entirety, applies to all railway companies. Certain railway companies may not, as a practical matter, perform each and every activity that the CROR governs. In this case, for greater employee clarity, the railway company's rule book must contain the rules that govern activities they do perform.

Those rules shown as OPTIONAL may be adopted by a railway.

When used by a railway, they will not indicate the word “OPTIONAL” in that company’s version of the CROR .

It is optional to print the CROR and Protection of Track Units and Track Work together as one book or separately as CROR book 1 and CROR book 2.
