Training - Session II [ENDED]

Hello hello!
Training was a success. And as expected, a sequel was unavoidable!
This train has a minimum level requirement of 2.
Here is the link. You know the drill, right? That's not going to be the link of the first cart right away. That would make the bots really happy.
Apply the following formula and you shall have the correct link: 04-05-03-01-02
It's needless to say but don't forget the slash at the end of the URL.
Shine a light to those who are lost by giving hints in the thread if you desire.
Thank you for your comments on the previous thread and on the giveaways. Keep 'em coming!
Good luck!
