The Gilded Bodhisattva Statue is the forty-seventh treasure that can be found in Uncharted 2: Among Thieves.
The Gilded Bodhisattva Statue is found in Chapter 14 - Tunnel Vision. This treasure is found within a train car that you are walking over. In other words, you don't have to ever enter this train car, meaning you're going to have to keep an eye out for this treasure's location, or pass by it all together. After sniping the aforementioned soldiers, begin to run forward. The train car next to the train car holding a haul of coal is the key. Work your way to the side of the car and drop down. You'll see an entrance into the train car from there. Launch yourself inside and walk to the far end of the train car's exterior (towards the way the train is going) to claim your treasure.
