And have the additional beneficial effect of pissing off the Enviro-Weenies as it passes them belching REAL smoke! I like it:
FIREMAN: Agghhh. I see em. They got signs, too.
ENGINEER: Alright! Lets pour it on, we usually go through here at about 5 mph to let people admire us, but we can go up to 40 mph. Let's pour it on-FULL SPEED AHEAD!
FIREMAN: begins tossing logs in as fast as he can) Can I pour some coal juice in there too? That'll REALLY make some steam for us, and we are going to see the thickest, blackest, gooey oil-filled and global warming particulate-filled cloud belching out you have ever seen! I hope they all have some Tide at home, because that stuff all comes out the top too!
ENGINEER: Yeppers!
FIREMAN: They aren't moving off the tracks on the bridge!
ENGINEER: No problem, we do have a cow-catcher...let's see, who do we have back there? Billy and Sue, you want to blow the whistle real loud?
BILLY AND SUE: (in unison) YAAAAYYYY! (fighting over the whistle, then both yanking it over and over again)
TRAIN: WOOOOOOOOOOOOO! WOOOOOOOOO WOOOOOOOOOOOOOOOOOOOO! WOOOOOO!
PROTESTERS: HEY HEY! HO HO! FOSSIL FUELS HAVE GOT TO GO! HEY HEY! HO HO! FOSSIL FUELS HAVE GOT TO GO!
TRAIN: WOOOOOOOOOOOOO! WOOOOOOOOO WOOOOOOOOOOOOOOOOOOOO! WOOOOOO!
PROTESTERS: (in confusion) Aggggghhh! HE'S NOT STOPPING! AAARRRHHHHHHHHH! (leaping off bridge into icy water below)
BILLY AND SUE: (in unison) YAAAAYYYY!
ENGINEER: (with evil grin) I hate Environmental Nazis!

And throw some dead leaves and grass into the firebox to make even more smoke.
