Chapter 68: The Steam Behemoth

The following months became consumed by iron, steam, and noise.

I had expected building the train itself to be difficult.

I quickly realized the locomotive was actually the easy part.

The rails were the real nightmare.

The first railway line I planned was relatively small compared to what I eventually envisioned. It would only connect several important areas throughout Aldric territory itself:

the industrial district,

the steel factory complex,

several storage depots,

and a mining route leading toward one of the larger roads exiting the territory.

Even that alone required absurd amounts of work.

Entire sections of forest had to be cleared while workers leveled uneven ground using shovels, picks, and explosives. Wooden sleepers were cut in massive quantities before steel rails from the factory were hammered into place section by section.

And I immediately discovered another problem.

Tracks could not simply go wherever I wanted.

Gradients mattered.

Curves mattered.

If slopes became too steep, the locomotive would lose traction or stall entirely. Sharp turns risked derailing the carts completely.

Which meant surveying teams became necessary.

Finn looked personally offended after I explained this.

"So not only are we building a giant metal monster now—"

He pointed toward the unfinished rail line stretching across the dirt.

"—but the ground itself also has opinions."

"Yes."

"I hate engineering."

Despite the complaints, progress continued steadily.

The industrial district transformed almost as rapidly as the railway itself.

New foundries appeared beside expanded machine workshops while steel production increased almost nonstop. Waterwheels powered hammers large enough to shake nearby buildings while smoke filled parts of the sky above the factory district.

The separate steel production complex especially expanded aggressively after the Blackwater mine operation succeeded.

Now that nitrate shortages were effectively solved, I could finally produce explosives in larger quantities without carefully rationing every barrel of gunpowder.

Which accelerated everything else.

Road clearing.

Mining.

Construction.

Excavation.

Even the workers started changing.

The original laborers who once struggled to understand rifles now casually discussed steam pressure, rail alignment, casting flaws, and ventilation systems while working.

Finn noticed it first one evening while watching several workers argue beside a stack of unfinished wheels.

"...We accidentally created industrial workers."

I glanced toward the argument nearby.

One man was loudly insisting thicker wheel flanges reduced derailment risk while another argued it increased friction around turns.

"...Apparently."

Finn looked disturbed.

"They’re using your words now."

"That tends to happen when people learn things."

"No. This feels unnatural."

Meanwhile the locomotive itself slowly took shape inside the largest workshop near the factory district.

Compared to the steam car, the machine looked enormous.

The frame alone required reinforced steel beams thick enough to support the weight of the boiler, engine assembly, fuel storage, and cargo load simultaneously. Multiple workers spent weeks riveting together the chassis while large steel wheels were cast separately inside the foundry before being machined into proper shape.

Unlike the steam car, the train did not need rubber wheels or complicated steering systems.

The rails handled direction automatically.

Which simplified some things.

And created entirely new problems elsewhere.

Wheel alignment became critical.

If even one axle sat unevenly against the rails, the locomotive could derail catastrophically at speed.

Finn discovered this personally during one early test involving an unfinished cart.

The entire thing jumped the tracks almost immediately before collapsing sideways into a ditch.

Finn slowly climbed out covered in dirt.

"...I think the rails rejected me spiritually."

"You were going too fast."

"It moved faster than walking!"

"The curve angle was wrong."

"That sentence means nothing to me anymore."

The boiler became the most dangerous part by far.

Much larger than the one used inside the steam car, the locomotive boiler required significantly higher pressure to move heavy cargo loads reliably.

Which meant thicker steel.

Stronger rivets.

Better pressure control.

And far more chances to explode catastrophically.

Several workers outright refused entering the workshop during pressure testing after one faulty valve burst hard enough to dent part of the ceiling.

Finn pointed toward the damaged metal afterward.

"See? Even the BUILDING thinks this is a bad idea."

I ignored him while adjusting another pressure regulator.

The piston system itself used dual cylinders mounted beside the main drive wheels. Steam entered alternating chambers while connecting rods transferred the motion directly into the large steel wheels resting on the rails.

The first time the unfinished wheels actually rotated under their own power—

The entire workshop froze.

CLANK.

HISSSSS.

CHUNK.

The massive drive rods slowly moved back and forth while steam escaped from the side vents.

The machine sounded alive.

Heavy.

Violent.

Industrial.

Workers gradually gathered near the workshop entrance staring silently at the partially completed locomotive.

One younger worker finally whispered:

"...It looks like a metal beast."

Honestly—

That was accurate.

The locomotive continued evolving over the following months.

The original design became larger almost immediately after I realized the first boiler lacked enough pressure capacity for meaningful cargo transport. Entire sections got rebuilt repeatedly while improved steel casting techniques slowly increased the quality of major components.

The rail network expanded alongside it.

Small bridges appeared across streams while embankments got reinforced using packed stone and timber supports. Maintenance crews constantly repaired warped rails and unstable sections while supply wagons carried steel and wood across the growing construction lines daily.

And slowly—

The railway began connecting the territory together.

Transport times dropped dramatically.

Heavy steel shipments that once required entire wagon teams could now be moved using rail carts pulled mechanically along completed sections.

Even without the locomotive finished yet, the railway itself already started changing logistics throughout Aldric territory.

Then finally—

After nearly five months of nonstop construction—

The locomotive was ready.

Or at least ready enough.

The entire industrial district gathered near the main rail yard the morning of the first full test.

Workers lined the tracks while smoke drifted upward from the massive locomotive resting near the newly completed rails.

The machine looked monstrous.

Large steel wheels rested beneath a heavily reinforced frame while the cylindrical boiler dominated the center section. Pipes crossed the sides beside massive piston rods connected directly into the drive wheels.

Coal filled the rear storage compartment.

Steam hissed softly from several valves.

And painted crudely across one side in white lettering—

ALDRIC INDUSTRIAL NO.1

Finn stared at the name for several seconds.

"...That sounds deeply threatening."

"It’s a train."

"It sounds like something that conquers cities."

Workers continued feeding coal into the furnace while pressure slowly climbed higher and higher.

The entire locomotive creaked softly.

Steam escaped from the valves.

Metal clicked beneath expanding heat.

Several workers slowly stepped farther away.

One older man quietly muttered:

"If that explodes we’re all dying."

Reasonable concern honestly.

I climbed into the control position near the center of the locomotive while Finn reluctantly followed behind me.

"I want it officially documented that I disagree with all of this."

"You said that about the steam car too."

"And I was CORRECT."

Pressure continued climbing.

The gauge slowly reached operational range.

Good.

I wrapped one hand around the main control lever.

The workers nearby watched silently.

Nobody moved.

Nobody even spoke.

Then slowly—

I pulled the lever.

HISSSSSSS.

Steam surged into the cylinders.

The massive piston rods jerked violently once.

Then again.

CHUNK.

CHUNK.

CHUNK.

The drive wheels slowly began turning.

The entire locomotive trembled beneath us while thick smoke burst upward from the smokestack.

And then—

The train moved.

Several workers physically stumbled backward in shock as the massive steel machine slowly rolled forward along the rails completely under its own power.

No horses.

No magic.

Just steam.

Steel.

Pressure.

The locomotive gradually accelerated while the pistons pumped rhythmically beside the wheels.

CHUNK-HISS.

CHUNK-HISS.

CHUNK-HISS.

Smoke rolled across the sky while the train moved farther down the tracks pulling several loaded cargo carts behind it effortlessly.

Finn grabbed the side railing tightly while staring ahead with wide eyes.

"...Leon."

I kept my eyes on the tracks ahead.

"What?"

"...We built a land ship."

I laughed slightly despite myself.

The locomotive continued gaining speed while workers farther down the rails scattered aside cheering and yelling in disbelief.

The entire machine shook violently across the unfinished tracks while steam roared continuously from the cylinders.

But it worked.

It actually worked.

And as the locomotive rolled across Aldric territory beneath clouds of smoke and steam—

I already knew this was only the beginning.

The railway project rapidly became the center of Aldric territory.

What originally started as a small industrial line slowly transformed into something much larger over the following months.

The first locomotive underwent constant modifications almost immediately after its successful test run.

The original boiler lacked efficiency.

The suspension rattled violently across uneven track sections.

The cargo wheels overheated during longer hauls.

And worst of all—

The locomotive consumed absurd amounts of coal.

Finn summarized the situation perfectly after one particularly terrible test run ended with half the workshop covered in steam.

"So to summarize:

the machine shakes like it’s possessed,

eats mountains of coal,

screams constantly,

and occasionally tries to explode."

I adjusted one of the pressure valves calmly.

"Yes."

"...And you’re happy about this."

"It means progress."

"That word has lost all meaning."

Despite the flaws, improvements came quickly.

Larger drive wheels improved efficiency over distance while better piston timing reduced wasted steam pressure. Additional water storage got mounted behind the locomotive while reinforced wheel bearings reduced friction significantly.

Even the rails improved.

The original tracks occasionally warped beneath the locomotive’s weight, especially during hotter days. Entire sections had to be rebuilt using heavier steel rails and better compacted foundations beneath the sleepers.

Now that I understood railway construction better, the second-generation tracks became dramatically more stable.

Gravel foundations.

Proper drainage trenches.

Raised embankments.

Reinforced bridge supports.

The line slowly expanded farther and farther across Aldric territory.

And with every new section completed—

Transport efficiency skyrocketed.

Steel moved faster.

Coal moved faster.

Machinery moved faster.

Even workers themselves began using rail carts regularly between industrial sites.

The railway had already started changing the territory before even becoming fully complete.

One evening Finn stood beside the locomotive while workers unloaded steel beams nearby.

"You know what’s terrifying?"

I barely looked up from the blueprint spread across the worktable.

"What?"

"You’re smiling at this stuff now."

I glanced toward him slightly.

"Efficient logistics are important."

Finn stared blankly.

"You sound like a conquering emperor."

"I sound correct."

The real problem revealed itself several weeks later.

At first I simply continued planning future expansion routes toward Blackwater Hollow.

The logic felt obvious.

The mine there now produced massive amounts of nitrate-rich earth while Aldric territory handled most of the steel manufacturing and machinery production.

Connecting the two industrial centers directly would completely transform transportation capacity between them.

Wagons were too slow.

Too limited.

Too vulnerable.

A railway solved all of that.

So eventually I gathered detailed regional maps across one of the larger workshop tables and started planning the route properly.

And almost immediately—

I realized there was a problem.

A major one.

Finn noticed my expression first.

"...What."

I pointed toward the map silently.

Blackwater Hollow sat completely enclosed inside Nightbane territory exactly as before.

Which meant there was no direct route from Aldric lands without crossing through someone else’s territory first.

Actually—

Multiple territories.

I studied the map carefully.

The outer sections weren’t too bad.

The railway would partially cut across the edges of two smaller neighboring baronies before entering deeper Nightbane lands.

That part was manageable.

Money solved small nobles surprisingly often.

Toll agreements.

Trade incentives.

Transport rights.

If necessary I could even offer rail access itself in exchange for land usage rights.

Most smaller nobles would probably accept immediately once they realized the economic value of railway connections.

But then—

There was the actual problem.

The deeper route.

The railway line leading toward Blackwater Hollow eventually passed directly through central Nightbane territory.

Not just the outer lands either.

The tracks would eventually run dangerously close to the Nightbane capital itself.

Practically through the duchy’s heart.

Silence filled the workshop while I stared at the map.

Finn slowly walked closer.

Then his face changed too. 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

"...Oh."

"Yes."

"That seems politically catastrophic."

"Correct."

The Nightbanes were not some minor noble family.

They were the second most powerful family in the Kingdom of Megan itself.

A family powerful enough to rival the royal family directly.

Their lands near the capital especially would be heavily controlled territory.

And now I wanted to run massive steel railways carrying industrial cargo, machinery, explosives, and steam locomotives directly through it.

Finn slowly rubbed one hand across his face.

"...You need permission from Duke Rosthwall."

"Yes."

"That sounds horrifying."

Honestly—

He wasn’t wrong.

Duke Rosthwall Nightbane was not somebody people casually negotiated infrastructure projects with.

Especially projects involving industrial expansion on this scale.

The duke already tolerated far more from me than most nobles likely would have.

Rifles.

Explosives.

Steam engines.

Factories.

Now I intended to ask him for permanent railway construction rights directly beside the Nightbane capital.

Finn looked toward the map again.

"...Couldn’t we just transport things by wagon once the railway reaches the outer territories?"

"Too inefficient."

"You answered that disturbingly fast."

I pointed toward the distance markings across the map.

"Gunpowder production in Blackwater Hollow is going to scale massively."

Then toward the industrial district layouts.

"The steel factory alone already consumes more resources every month."

I looked back toward the planned railway route.

"If we want true industrial expansion, the railway has to connect fully."

Finn stared at me for several moments.

Then sighed heavily.

"So we’re going to ask one of the strongest men in the kingdom if we can build giant smoking metal roads across his territory."

"Yes."

"...I miss when our problems were normal."

I ignored him while continuing calculations.

The route itself would actually be ideal once completed.

The terrain near the capital remained relatively flat compared to the forests surrounding Aldric territory. Construction would become easier there.

And strategically—

The railway would massively benefit the Nightbanes too.

Faster logistics.

Rapid transport.

Military movement.

Trade expansion.

The duke would absolutely understand its value.

The real question was whether he trusted me enough to allow it.

Or more accurately—

Whether he trusted industrial infrastructure capable of changing the kingdom itself.

Because the moment railways spread beyond one territory—

Everything changed.

Trade.

War.

Economics.

Communication.

Power itself.

And somewhere in the back of my mind—

I already knew this conversation with Duke Rosthwall would probably decide the future of the railway project entirely.
