Thanks to MJ for the tip off about some Woolworths marked boxes on BM7 today.
Despite the sun down, I thought I better see what these boxes were.
One the train were five Woolworths marked 48ft containers, marked as AEDB, in the 916000 series. The code is an Aurizon code, so they are obviously marked for the customer.
From the sighting, it looks like the first group of boxes (maybe 10) are marked for Woolies as they were numbered all as 91600x. Also sighed were some new Aurizon marked boxes in the same batch, numbered 916016 and 916024 (last photo of this blog).
