thomas and friends mini series

Has anyone found the new 2018 3-Packs 3&4 at retail level? If yes, do you know if the trains have the ‘classic style’ chassis or the ‘new style’ chassis? If you don’t know the difference and you have these packs could you upload a picture showing the side view of the cargo trains included with them. Thank you very much. I’m compiling a variation list of the trains and these are the only packs I haven’t seen yet.

Sorry I meant 7-Packs 3&4
