1. This is about as close to a cutscene level as you can get, but I provide it here for consistency. Ride the train for a very long way, including over this bridge.
2. You can choose to engage these enemies or just hunker down inside as the train speeds past.
3. A brief cutscene plays of the train arriving at its destination.
4. Exit the train and follow your comrades.
5. A cutscene shows Longwood's train passing over the explosives. The train is destroyed in the explosion that follows and the next level loads.
