Train 2025 Collection trade-ups
A trade-up contract takes 10 skins of the same rarity and returns one skin of the next rarity, from the collections of your inputs. Valve doesn't publish the exact odds; calculators and most guides use this model: each input gives its own collection a 10% share, and inside a collection every skin of the next rarity is equally likely. On that model, with all 10 inputs from the Train 2025 Collection each possible result below has the chance shown; with 5 of 10 inputs from here, halve it.
Industrial x10 → Mil-Spec: 25% each (float range in grey)
- FAMAS | 2A2F 0.00–0.86
- Glock-18 | Green Line 0.00–1.00
- UMP-45 | Late Night Transit 0.00–1.00
- XM1014 | Run Run Run 0.00–0.75
Mil-Spec x10 → Restricted: 33.3% each (float range in grey)
- MAC-10 | Derailment 0.00–0.70
- Tec-9 | Whiteout 0.06–1.00
- Zeus x27 | Charged Up 0.00–1.00
Restricted x10 → Classified: 50% each (float range in grey)
- M4A4 | Hellish 0.00–1.00
- MP9 | Latte Rush 0.00–1.00
Classified x10 → Covert: 100% each (float range in grey)
- AWP | LongDog 0.00–1.00
- The Covert skin at the top of the Train 2025 Collection can be reached by trading up Classified skins. The 5-Covert knife and glove trade-up gives a knife or gloves from the collection of one of its inputs, and this collection has none, so its Covert skins don't work there.
StatTrak: none of these skins exist in StatTrak, so every trade-up into this collection uses non-StatTrak skins.
Souvenir versions of Train 2025 Collection skins come from souvenir packages; the game data lists 2 packages that can contain them, for example the Budapest 2025 Train Souvenir Package. Since the May 2026 update Souvenir skins can go into trade-up contracts, mixed with normal ones; the Souvenir status is removed and the result is a normal skin.
The float of the result depends on the floats of your inputs and the result's own range: see how the trade-up float is calculated and how trade-up contracts work.
