Good to see already ramping up the new service... MILAN EXPRESS ETA is 5/18, so that with the Med traffic is going to be busy busy.
I noticed some 132 videos out in Toronto they seem to be tupet/filet the Hapags with domestics for Montreal. With trade balances they way they are, a lot of empty boxes evacuate back to Europe so good chance many but not all of these are empty boxes headed back.
A 'TEU' just stands for twenty foot equivalent but railroads count a container as a 'intermodal unit' individually and a load regardless of if is loaded or not.. since the container in a well car is a load.
Hapag has a pretty good spec book here for boxes, I've used it a lot in the past. It gives you the ISO code too which a lot of folks use, such as 22G1 for a standard dry 20' box
