I reached Level 10 (74,000AP) with the Class 33 GRN Engine but the "Class 33: Solid Steel Construction" trophy for reaching Loco Level 10 did not pop. I happened to be grinding its distance trophy 330mi so I was using the right engine as I just got that one and should've got this one less than 5 minutes later, but did not, my current level is Level 11 75,799/84,000 so I an nearly 1800AP past Level 10.
Update: It unlocked at Lv11 84000/84000AP In any case I had a cloud save from before Lv10 so I was grinding the last AP for Lv10 on my PS4 at the same time, but Lv11 came first with the trophy on my PS5.
