From next time onwards, if at all u want to correct any info that u made few minutes or hours ago, instead of creating a separate TL, kindly press the "Report" button on the Timeline, select "Other" and type "Please issue Fixit" in the box. FM's will issue fixit in a few mins, and u can correct the info, & ask that concerned person to CNF.
Fixit works out for everything except Platform numbers, halt notes & loco additions.
