At first, it did start with the dates of the week it started. Lately it seems that instead of the date it started, members have been just "Of the Week".Assuming that members are following the posts every week.
Freight car of the week started out without a date, but Memebers have been posting the start dates on Locos of the week.Though the very first FOTW(boxcars) ran for almost a month, and by looking at the thread, members are still posting today.
