There was, indeed, no boom yet.

In fact, as the seconds dragged on longer and longer, and the train kept rolling down the tracks, swaying and bumping, there was no sound of a deafening fiery explosion, no noise of metal being ripped asunder and tearing through the rest of the cars, no screeching of wheels being knocked off the tracks, nothing. Not even a meager firecracker.

Not only was there no boom yet, it seemed like there was no boom at all. Just the sounds of the train still clacking down the rails, despite being shot full of holes in certain areas. It was just...quiet.

Mako would have been complaining about being hefted into the air by the large cat, and carried after their comrades, but really, what was there to say? Oh no, I just can't wait to be blown up, let me down you purple monstrosity?

Not likely. The shark kept his mouth steadfastedly shut as Big, having been roused to wakefulness, heaved both him and Sir Corin after their compatriots, dropping the shark and the aardwolf down alongside Casey once they reached the boar's compartment.

A momentary pause.

"No boom?"

Huffing and puffing and completely unaware that he was sitting on a face-down Mako, Sir Corin was less than amused.
"Dastardly tricks! Fiends and villains! What debauchery is all this nonsense?"

Okay, so, that was an awkward moment.

— Not because of the lack of explosions, but because Big the Cat had tried to fit himself in a compartment car on a train, and inside a compartment, too. Once everything came to natural equilibrium, though, and everyone got comfortable, it mostly likely ended up with the purple cat just... occupying the doorway, and several squished-out feet in every direction beyond, with the outer wall of the train bulging.

The lack of explosions was awkward, too, though, make no mistake. Casey, after sitting silently for long enough, finally commented.

"... I don't think anything's gonna blow up," he declared in scholarly, concise observation of the facts.

He looked sheepish a moment.

"Maybe we oughta... now... at this time, that is, maybe,... go try to find out what's goin' on. I think."

He cleared his throat.

A couple minutes later (however long it took them to extricate themselves from the Big-created enclosure they were trapped inside of, and catch up on details from Geoff), a few members of the party were cautiously moving their way back through the train, past leery passengers, and through the bullet-riddled baggage car, back to where all the action had happened in the freight car.

Casey was the first to climb up on the roof and drop in through the open hatch, landing heavily with a grunt and clunk on the hard floor. The side door was still open, and frigid air curled and whipped around the interior. The interior was a mess. Wary, the hog scanned around, gunarm at the ready, looking for signs of life or hostility.

He soon found a survivor, but not a hostile one. The super-colorful bird fellow was digging through a broken crate, setting aside debris, when they entered, and he turned and quickly put his hands in the air.

"Don't shoot, don't shoot," he blurted in a tense, but tired-sounding plea. He spoke clear English and wasn't trying to jump them; this was a start.

"I was one of the ones defending, not attacking," replied the bird. "Those men stole from us."

True enough, he was not clad as the troops were, so he wasn't in their lot — not that anyone would know where he or any of his longcoat-wearing cohorts had come from in the first place, though, unless they had been paying special attention back at the train station.

"What's it matter, anyway?" the guy groused tiredly, giving Corin's spear a dirty (but unaffected) look. "What are all you people even doing here, anyway?" With distaste, he added, "Don't tell me you're just... nosy passengers."

The pheasant lulled his head. He looked (perhaps understandably) sullen about the whole thing.

"Maybe you shouldn't have," he replied indifferently. After a deep breath and sigh, though, he spat it out. "It was the Norden Circle — supposed to be some old... something that'd help us stop Eggman. Li Fang's taken it, though, so even if it does work, it definitely won't be helping anybody."
