[Form L.]—Annulling or Superseding an Order.
Order No. —— is annulled.
This will be numbered, transmitted, and signed for as other orders.
If an order which is to be annulled has not been delivered to a train, the annulling order will be addressed to the operator, who will destroy all copies of the order annulled but his own, and write on that:
Annulled by order No. ——.
An order superseding another may be given, adding, "this supersedes order No. ——," or adding, "instead of ——."
EXAMPLE.
No. 1 and No. 2 will meet at Sparta instead of at Thebes.
An order which includes more than one specified movement must not be superseded.
An order that has been annulled or superseded must not be again restored by Special Order under its original number.
