This level is essentially just a boss fight. Remember that guy who impaled Kim a few acts ago? Well he's back to stop you once and for all. There are multiple strategies for this boss so edit in any if you have them.
Suggested Armarments
For this boss there are several weapons that are ideal. First off you're going to want something to disperse his shield; both grenades and Torque Bows do the job so fill up on those. Also you'll need a sniper rifle, whether or not you're good with it. If you have a partner then they'll need a sniper too.
Strategies
The first thing you should do is take cover. General RAAM has two attacks that he can use on you. The first is a huge gun unlike anything else in the game. You don't really need to know what it is though just know that it can kill you in a few seconds.
The second attack is the Kryll. The Kryll are a vital factor in this battle because they are both his defense and offense. Normally the Kryll will fly around RAAM like a shield. When this shield is up nothing will damage him. There are three ways to destroy the shield shoot him with the Torque Bow, chuck a grenade near him, or wait for RAAM to send them after you. No matter which you use make sure to snipe him in the head when the shield is gone.
This sounds pretty simple, but there are complications. RAAM will slowly move toward you, which is bad. The only thing more dangerous than RAAM at a distance is RAAM up close. But here's the catch, if you leave your cover then you risk being mauled by Kryll (because most of the train is dark.) So when RAAM gets close hit him with a grenade or Torque Bow and run towards the other end of the map.Once you hop over the cover you'll find that the map is symmetrical. Turn around and repeat your original plan of sniping and you'll eventually defeat him.
