This is one of the Dungeons for the recently released expansion Warlords of Draenor.

There are three boss encounters.

Railmaster Rocketspark and Borka the Brute Pauli Rocketspark is chief foreman of the Grimrail Depot, a post assigned to him by Garrosh. Borka is his apparently "dim-witted" assistant.

Railmaster Rocketspark

VX18-B Target Eliminator Launches Missiles at a target or two, doing damage to anyone near that target. Probably a good idea to spread out for this encounter, or at least the Missile Phases.
X21-01A Missile Barrage Missile Volley directed at one or two players, every second for a minute. Does low damage, but it will add up, so healer attention will likely be necessary. We don't know yet what type of debuff this will be, or if this will be cleanse-able by the normal methods.
Locking On!
New Plan! Occurs when Borka is slain.

Borka the Brute

Slam AOE damage and AOE interrupt. You'll likely want to stop casting when this cast is finishing.
Mad Dash A directional charge, doing significant AOE damage and AOE interrupts along the charge line. Best to avoid.
Unmanaged Aggression Occurs when Pauli is slain.

Nitrogg Thundertower A cannoneer, he will shoot the players with cannon fire, which should be LOS'd. The cannon must be exhausted, either by player assault or by the cannoneer's use of it, we do not yet know. He becomes killable once the cannon is down. There will also be a stream of adds during this fight.

Reinforcements:

Blackrock Infantry?: Blackrock Plated Gauntlets Physical damage, wording indicates a possible a percentage-based damage modifier on the attack.
Blackrock Gunner: Shoot Shoots Bullets.
Artillery Engineer: Black Mortar Hurls a barrage of fiery mortal shells at the target, doing damage to all in a short range of the location. A DOT is also applied, dealing damage over 12 seconds.
Blackrock Grenadier: Blackrock Grenade Tosses a grenade at a "targetted location" dealing fire damage to anyone close-by.
Blackrock Explosives Expert: Plant Bomb Timed Bomb that explodes after a certain amount of time, dealing damage to anyone within 13 yards. Probably best to, if possible, run away as you see it being planted.

Nitrogg Thundertower: The Journal Seems to indicate he will cast most of the same spells as his soldiers, with the addition of a Suppressive Fire spell.

Suppressive Fire A quick succession of uninterruptable physical damage, that also interrupts casts. Lasts 10 seconds. The damage is LOS-able.
Black Mortar Hurls a barrage of fiery mortal shells at the target, doing damage to all in a short range of the location. A DOT is also applied, dealing damage over 12 seconds.
Blackrock Grenade Tosses a grenade at a "targetted location" dealing fire damage to anyone close-by.
Plant Bomb Timed Bomb that explodes after a certain amount of time, dealing damage to anyone within 13 yards. Probably best to, if possible, run away as you see it being planted.

Skylord Tovra Fight takes place on a platform. You will engage the Thunderlord General; however, he also has a pet Rylak who will continually create pools of Diffused Energy, which do damage if you stand in them, so this fight will involve a bit of movement, and will likely need to be completed as quickly as possible, in order to avoid running out of ground to run on.

Freezing Snare A frost trap that tethers you and anyone nearby in place when tripped. If this is cleanse-able, it will need to be cleansed quickly, especially in cases where the person is tethered in a Diffused Energy. It MAY be helpful to intentionally trip this trap when a) there is no Diffused Eneregy nearby and b) the rylak's Diffused Energy spell is on cooldown. This could possibly prevent a squirrely situation later on.
Spinning Spear ~~Throw Axe~~ Armor-Ignoring large chunk of damage, that additionally knocks down the target.
Diffused Energy Creates a pool of lightning on the ground that does damage to anyone standing within it. These pools may not dissipate, and will accumulate on the platform, so this fight may be a dps race.
Thunderous Breath AOE Nature damage to everyone on the platform.
Hunter's Mark Hurls a spear at a target, exploding in fire damage within 8 yards. (Heroic)
~~Explosive Spear Hurls a spear at a target, exploding in fire damage within 8 yards.~~

1. According to Muffinus on Twitter, the Iron Skyreaver is a Rylak, so a Rylak is a Chimaera-like beast.

Train dungeon?

I'm the only one who thinks it's awesome?

Deeprum tram exists. There has been technologic advancement though. The entire catalyst for WoD was Siegecrafter Blackfuse creating a new type of engine (the Iron Star as seen in the Garrosh fight) and allowing for a military industrial revolution.

Comment by dreadmoor64

Railmaster Rocketspark and Borka the Brute are the first boss combination in Grimrail Depot, who are fought simultaneously and receive buffs when the other dies.

Both should die close to the same time, and Borka the Brute's Mad Dash used to knock Railmaster Rocketspark off the boxes and stun him.

Railmaster Rocketspark is un-tankable and ideally should be ranged down, as he is usually out of melee range.

He casts X21-01A Missile Barrage and VX18-B Target Eliminator from on top of boxes or at range, changing position often.
When Borka the Brute dies, he gets a New Plan! and begins Locking On!, which should be avoided by killing both simultaneously.
He can be knocked off the boxes and stunned by Borka the Brute's Mad Dash.

Borka the Brute should be tanked with melee DPS.

The tank and melee should move away to avoid his Slam.
When Railmaster Rocketspark dies, he gains Unmanaged Aggression, which should be avoided by killing both simultaneously.
His Mad Dash should be avoided by all, except the tank. The direction of his Mad Dash is indicated by a red arrow on the ground at his feet.

DPS should split damage evenly between the bosses and the tank should aim Borka the Brute's Mad Dash towards Railmaster Rocketspark to knock him off the boxes and stun him.

The tank should face Borka the Brute towards Railmaster Rocketspark near the center of the room.
Everyone else should not be positioned between them.
Ranged should DPS Railmaster Rocketspark.
Melee should DPS Borka the Brute
If there is an imbalance in DPS, ranged can partially DPS Borka the Brute, or melee can DPS Railmaster Rocketspark when he re-positions to the ground, to maintain equal DPS on both.
When Borka the Brute is about to cast Mad Dash, the tank should start walking him towards Railmaster Rocketspark.The closer the distance; the less likely to miss and the less distance melee has to close.
The tank should aim the Mad Dash's red arrow at Borka the Brute's feet precisely at Railmaster Rocketspark. The tank can run directly to Railmaster Rocketspark when casting has begun, as long as he turns to face the charge.
If Borka the Brute's Mad Dash hits Railmaster Rocketspark or the boxes directly below where he is, it will knock him off the boxes and stun him.
Once Railmaster Rocketspark is down and stunned, DPS should AOE both.
Repeat
Both should die at the same time to avoid New Plan! and Unmanaged Aggression.

Comment by dreadmoor64

Nitrogg Thundertower is the second boss in Grimrail Depot. The fight occurs in three phases on a moving train whose wind pushes characters back.

Phase 1 - standard tank and spank to 60%.

The boss is positioned inside an enclosed rail car preventing the wind debuff.
The party should move out of the small red pulsing circle indicating the AOE range of Blackrock Mortar when cast by the boss.
At 60% the boss retreats to the other end of the rail car, and mounts his Assault Cannon, becoming un-tankable.

Phase 2 - the party uses Blackrock Mortar Shells to destroy the Assault Cannon.

The party can advance in the wind along the left side of the rail car avoiding Suppressive Fire behind pillars and other cover.
The adds should be tanked behind the furthest most left pillar to avoid the Suppressive Fire and the wind debuff and be close to Blackrock Turrets.
The party should stack on the tank and avoid standing in Slag Blast.
DPS the adds until the Grom'kar Boomers die.
DPS should loot the Blackrock Mortar Shells from Grom'kar Boomers.
DPS should use Blackrock Mortar Shells in the Blackrock Turret to destroy the Assault Cannon.
The tank should loot Blackrock Grenades from Grom'kar Grenadiers.
The tank can use Blackrock Grenades to control the adds. Use the special action button in the middle of the screen or bound slot. Wait until the adds come to the tank, so looting doesn't expose anyone to Suppressive Fire.

Phase 3 - Once the Assault Cannon is destroyed, the boss can be killed.

The tank should continue to use a pillar or other obstacle to avoid the wind debuff.
Blackrock Grenades and Blackrock Mortars can be thrown at the boss for DPS. Use the special action button in the middle of the screen or bound slot.
The party should move out of the small red pulsing circle indicating the AOE range of Blackrock Mortar when cast by the boss.

Note: Be sure to pick up Iron Autocannon to completeCold Steel.

Skylord Tovra is the last boss in Grimrail Depot. There is no wind debuff, but Rakun flying above breathes Thunderous Breath onto the rail car.

The tank will continuously re-position the boss for the party to avoid the pools of Diffused Energy and Freezing Snare. Being frozen in a pool can wipe a party.

Periodically the boss will mark a target with a Hunter's Mark. The character marked should move to avoid Spinning Spear cast at their position.

Jaynor and Tychus would envy this, raiding running trains for treasure and kills, but they'd use Vultures... old times.

In the rear cars section, there is a small crate that when used will release a number of serpents.

Snakes on a train, who'd have thought it?

So at least on Heroic I can't see any way to enter this dungeon after completing the train bosses and get to the depot again. I'm dropped right into the rear train cars and can't go backward.

Can't go forward much either; can't get to the end after the wreck, can't get back to the entrance, can't do much of anything. If the thing you wanted isn't on the train you're out of luck and your hearthstone better be off cooldown.

CHALLENGE MODE TIP - Nitrogg Thundertower (Boss 2/3)

The following tip can shave a large chunk of time from the 2nd boss encounter, giving you that extra boost to get Gold!

The first phase of this boss involves fighting Nitrogg Thundertower in the cramped rear portion of the train car, during which the group should spread out to minimize the damage from the Blackrock Mortars and Blackrock Grenades that he casts.

At 60% health, he transitions to Phase 2, wherein he retreats to his Assault Cannon in the front of the car, and the sides of the train car open up allowing access to the middle and front portions of the encounter area.

One of the time consuming portions of Phase 2 involves killing adds, looting them and using Homing Shell on the Assault Cannon. Each shell does 25% of the cannon's health, so 4 shells alone are required to break Nitrogg out (or 3 shells and another 25% of direct damage to the cannon).

It's possible to annihilate the Assault Cannon with a SINGLE Homing Shell thus shortening this encounter SIGNIFICANTLY.
To do so, you need 1 Shaman, or 2 Hunters (a single Hunter works, it is just less effective and won't shorten the fight by as much).

A Shaman should be using with Charred Glyph.
A Hunter should use Deterrence with Charred Glyph.

Below are the steps to follow for this strategy:

The tank and all DPS, including the Shaman/Hunter, should move to the front of the car. The Shaman/Hunter should move right up next to the Assault Cannon and start attacking the Assault Cannon (to "bait" the Slag Blast).

If the Shaman is a healer, have another DPS start attacking the cannon.
The remaining DPS, tank and healer should start attacking the first two adds, which will appear at the front of the car, consisting of a Grom'kar Boomer and a Grom'kar Gunner. The Grom'kar Boomer should be the DPS priority.

All group members should remember to line-of-sight when targeted by Suppressive Fire.
Once the Grom'kar Boomer is dead, it's body becomes lootable and one DPS (who should be previously assigned) should loot the Blackrock Mortar Shells and get into the Blackrock Turret closest to the Assault Cannon, ready to fire it when the time is right.
As soon as Slag Blast appears (fire on the ground around the Assault Cannon), the Shaman should drop the glyphed and ALL party members (except those targeted by Suppressive Fire and the one DPS in the Blackrock Turret) should run INTO the fire (Yes, it's ok to stand in fire here!) and someone should track of the stacks of Slag Blast on the Assault Cannon.

The more people that stand in the fire, the faster the stacks will appear on the cannon.
Note that all the while all of this is happening, more adds will be spawning and should be picked by the tank.
Once the Assault Cannon has 9 stacks of Slag Blast, everyone should move out of the fire, and the DPS in the Blackrock Turret should use Homing Shell on it. This should INSTANTLY destroy the cannon, and initiate the final phase of the fight, where Nitrogg Thundertower reappears and needs to be DPSed down. No further adds will spawn at this point, although all existing adds will remain.

A Hunter can used glyphed Deterrence to the same effect, but a single hunter may not reach 9 stacks of Slag Blast on the Assault Cannon, even with 2 charges of deterrence. Two hunters would definitely be effective in doing so. Even if not quite hitting 9 stacks, a hunter performing this trick will still shorten the length of the fight (likely requiring only 2 Homing Shells to break Nitrogg out, rather than 3-4 normally).
It is essential to be quick about moving out of the fire after 9 stacks are reached, as the Slag Blast will stack on party members quickly once has expired.
Listed at the end of this post is a WeakAura that can be used to track the stacks of Slag Blast, with an alert once 9 stacks are reached.
DPS players should kill any remaining Grom'kar Gunners, loot the bodies, jump into the Blackrock Turret and use Shrapnel Cannon to help finish off Nitrogg and the remaining adds quickly.

NOTE: In theory from a Warrior should work the same way as , but this hasn't been tested, and it is unknown how many stacks of Slag Blast you can reach with this ability.

TL;DR version: Have a DPS attack the cannon at close range. When fire appears around the cannon, drop the Shaman should drop the glyphed , have everyone move into the fire, and have someone shoot the Homing Shell from the Blackrock Turret once there are 9 stacks of Slag Blast on the Assault Cannon. Kill the boss and remaining adds.

A VIDEO GUIDE to the above strategy is available here. Thanks to Jace DK for this great video.

There are a couple of WeakAuras that can be helpful when executing this strategy.

To use them, you need to install the WeakAuras 2 addon, then do the following:

Type /wa in chat to open the WeakAura interface
Click New, then select Import
Copy the text in the following code box and paste it into the WeakAura import field, then click Done
Click the "Import" button on the confirmation in the middle of the screen to add the aura

Below is a WeakAura string that can be used to track stacks of Slag Blast on the boss, with a custom alert once 9 stacks are reached.

To modify the aura to work for a buff like Deterrence or Spell Reflection, do the following:

Change the "Type" to Aura
In the "Aura Name or ID" box, type the name of the buff (e.g. Mass Spell Reflection) and click "Okay"
Make sure the "Unit" dropdown shows "Player, and the "Aura Type" is "Buff"

If you stealth passed the last set of mobs where Skylord Tovra is and kill the mobs just on the other side on the last car, the gate will go up and you will be stuck there with no way out except to Hearth.

It is possible to make this dungeon fail such that the final boss Tovra cannot be attacked. During the next to the last scene, if you are able to rush forward past the mobs and portal all the way forward and then turn around and kill them all, a gate will rise behind you that prevents access to Tovra and her mount when they appear. Blizzard simply didn't anticipate this action when scripting the dungeon; the gate was intended to confine the players nearer to Tovra, but in this case it confines them away from her. Well done again, Blizzard.

Boarding the train isn't obvious for first timers. Here's how:

You can't board the Grim Rail by walking/jumping onto it from the main floor after you kill Borka and Rocketspark, the first combo-boss. After you kill them, look for a newly open door off the platform, which is gleaming with flamelight. You have to run up a ramp dodging flaming bombs and a few mobs. At the top of the ramp (it's a few levels), run ahead and a cinematic will start showing you and your party jumping down onto the train.

For SL Season 4 M+, after Railmaster Rocketspark, you need a minimum of 23% before going up the stairs to fight the second Grimrail Bombardier. Else, with enemy forces <100%, Skylord Tovra will not spawn at the end, and the M+ keystone will basically fail.

There are 3 Grimrail Bombardiers after the first boss. In mid and high keys, the first Grimrail Bombardier will turn into Zul'gamux, and the grunt, a lesser dreadlord. With both of them killed, you will have 26% even if you skip the opening 2 Grimrail Overseers at the corner.

In low keys, you should not skip the opening 2 Grimrail Overseers at the corner before the first boss. With the optional grunt under the rafters, you will have 24% before the 2nd Grimrail Bombardier; Without the grunt you will have 23%. However, if you skip any Grimrail Overseers, you will be unable to reach 23% before fighting the second Grimrail Bombardier. You can either continue to the end and find that the key has irreversibly failed, or be wise and immediately turn back and kill the skipped Grimrail Overseers.

Rocketspark and Borka – Railmaster Pauli Rocketspark, chief foreman of the Grimrail Depot, has been enlisted by Garrosh Hellscream to build the technology required for the Iron Horde's infrastructure. Given the dim-witted assistant Borka to do the heavy lifting, Rocketspark set about building the Grimrail.
Nitrogg Thundertower – With a zeal for flame and explosives, Nitrogg was a natural fit in the mechanized and weaponized army that Garrosh's plans brought to Draenor, and he has risen quickly through the Iron Horde. He oversees the artillery on the Grimrail, and is eager to break through the defenses around Shattrath and conquer the enemies of the Iron Horde within.
Skylord Tovra – Before the rise of the Iron Horde, Tovra had never ventured beyond the frigid tundra of Frostfire, where she led groups of Thunderlord trackers to snare and capture the fiercest rylaks on Draenor. Her mastery of rylaks has made Tovra an invaluable asset, and she now commands the aerial forces of the Iron Horde.
