So, i was looking at the new battlepass, and stumbled at the last playercard in the bp. As a portuguese, i was clear that was an "Elétrico", a kind of public transport that's a symbol of portuguese culture. In image 1 you can see the player card, and in image 2 an "Elétrico".

​

Moreover, i was looking into the schedule of the trains, and it looks like there isn't a number 27, like in the playercard, maybe it was only constructed for the ecodome, possible location of the new valorant map.
