Round 1
[sblock=Answer to question] The rail is moving at a considerable pace, so falling off would be rather... bad.
However, do keep in mind that if you are ever push/pulled off of a ledge of something, you get a save to grasp the edge. IF you were to be pulled/pushed/slid off the edge and you happened to fail your save, you would take 5d10 falling damage. In order to catch up, you will need to spend two full rounds moving at sprinting pace (2 double moves while running) and succeed in a DC 15 athletics check to grab a hold of the last rail car and pull yourself aboard. [/sblock]
Tracker feels a tingle in body, a shiver running through his chassis and sees dozens of ghostly flowers sprouting from him. Angered at the display, he pulls his cart over to the hole in the west side of the rail and jumps aboard. In mid-air, the warforged's body twists and reshapes itself into the metalic semblance of a wild cat, it's tail a wide, tear-shaped plate of spikes. As it's back feet hit the floor of the rail car, the wild cat leaps forward and around you, landing in front of the meddling arcanist.
Roaring with a fierceness that shakes the rail car, the wild cat slashes Masumi with both of it's front claws, drawing several lines of blood across her chest and shoulders. The cat grins at the three opponents he sees before him and backs off a step, daring them to attack.
The rest of Trackers crew follow his orders and surge north, firing off their elemental cannons. The blasts hit the rail's main engine dead on and flames begin to spew forth from the devastation!
[sblock=Actions]
Tracker moves aboard and uses Form of the Relentless Panther. He then uses Form of the Relentless Panther Attack to shift over to Masumi and slashes her for 16 damage and ongoing 5 damage (save ends). As a free action, he marks Grryth, Gurdan, and Masumi.
The rest of the crew fire their cannons at the lightning rail's main engine and hit, starting the skill challenge below. [/sblock]
[sblock=Skill challenge: Engine Fire!]
The lightning rail's main engine is on fire! This is a Complexity 2 skill challenge (6 successes before 3 failures).
Any round in which NO ONE attempts to deal with the fire will count as a failure.
No skill is impossible to use if used right and is creatively described. Please no one-line descriptions of using skills, especially if you are trying to use it out of the norm. I may give bonuses for creativity! Amuse/impress me and see what happens! If you want to use a power instead of a skill, go for it, but it better make sense and be described well.

[sblock=Question]Say, hypothetically, someone were to fall out of the train or off a cart. What happens? I mean, even if there's no fall damage, we're probably moving so quickly that they'll be out of the fight.[/sblock]

Surprise round!
Masumi says, "are those the bad guys?"
Minor action: Masumi places her Warlock's curse on Tracker (if there is an appearance to a curse it is flowery)
