On (mm/dd/yyyy) I was assigned to the (CIRC7 pool turn ####) called on the Train-ID at 00:00 to take the train to (CIRC7). En route I was instructed by the train Dispatcher Name to stop my train at (CIRC7) and (give as much detail as possible on the work performed. It could be performing service that a local usually does and didn’t complete. On the Lynndyl sub a Martmar flip as we call it would be a valid claim). We stopped our train at (CIRC7) at 00:00 and went to (CIRC7) performing required service and returning back at our train at 00:00. Claiming 1 basic day for NON emergency side/lap back trip as per Rule 28 and rule 24 of the Salt Lake and Portland Hub agreement dated July 1, 2008.
