Pouring Forth Oil IV, Red Dead Redemption 2 Mission
1. Drive the wagon to the railroad crossing / Park the wagon on the tracks
Take the oil wagon to the ambush site and place it on the railroad tracks.
Arthur will climb to the top of the wagon while others will hide near the tracks. As expected, the train will stop before the obstacle.
2. Board the passenger car
When the train stops, jump off the wagon, go and board the first of the passenger cars.
3. Follow John / Beat the passengers
John will start collecting valuables from the passengers. Follow him.
Four passengers will try to resist. Your task will be to beat these passengers and convince them to cooperate.
When you reach the third passenger car, John will no longer need your help and you will be able to move forward.
4. Check on Sean
After a while, you should see Sean trying to get into the cargo car. Unfortunately, he will be overpowered by a guard who is inside.
Draw your weapon and eliminate the guard Sean's in trouble with.
5. Take out the guards
A second guard will appear on the roof of the wagon, and then two more will come to the wagon. If you want to earn a gold medal, then you must kill them before Sean recovers and starts shooting at them. Since one of the requirements to earn a gold medal is to get 10 kills in Dead Eye, you should use that skill.
6. Rob the baggage
You now have to quickly, because you don't have much time for this, steal everything from three cabinets and a chest. All of them will be marked on the minimap.
There is also a bottle of Fine Brandy in the car but it's not required to be picked up to complete the gold medal requirement.
7. Take out the lawmen
After a while, or when you rob a whole baggage car, the law enforcers will approach the train and the shooting will begin. Use crates as covers and eliminate them. They will attack in waves from all sides and there will be a lot of them.
Remember, that you have to get a total of 10 kills in Dead Eye to earn a gold medal.
8. Escape the law
When you've eliminated all your opponents, you'll jump off the train. Get on your horse and as soon as possible move away from the red search area. The easiest way to do this is to just ride northwest along the railroad tracks until you're safe.
When you are safe, you will split the loot and each member of your group will go their own way.
