The Arrival of the Materials

October 18th, 1880.

The raw materials for the air brake system had finally arrived at the R&D facility. Matthew, alongside the team of engineers assigned to assist him, gathered eagerly around the crates as they were unloaded. Metal cylinders, lengths of durable piping, high-tensile springs, and valves filled each box. The reality of his design was now within reach, ready to be shaped into something functional.

Matthew clapped his hands together, drawing the team's attention. "Alright, everyone. We've spent the past weeks familiarizing ourselves with the design and preparation, but now it's time to bring it to life."

Tanner, still reserved, gave a curt nod, folding his arms as he eyed the materials. "I hope all this theory of yours holds up. We're dealing with materials and a system that haven't been tested in this configuration."

"It'll hold," Matthew replied confidently. "But let's take it one step at a time, starting with the compressor. We'll need to build it to withstand high pressure without any risk of rupture. Tanner, I need you to inspect the casting quality on the cylinders."

Tanner's brow furrowed, but he gave a small nod, moving to examine the cylinders. The rest of the engineers dispersed to their designated tasks, following Matthew's instructions. The workshop filled with the clanging of metal, the hiss of welding torches, and the focused concentration of craftsmen absorbed in their work.

As the compressor slowly took shape, Matthew moved between workstations, offering guidance and making adjustments. Each component, from the central piston to the intricate network of valves, needed precision. Even a slight miscalculation could jeopardize the system's efficiency—and its safety.

Several hours later, Tanner approached, his hands coated in metal dust. "The compressor's structural integrity checks out," he said, his tone grudgingly respectful. "Next?"

Matthew straightened, meeting Tanner's gaze. "Next, we test it with the reservoir. I want to see if it can sustain the required pressure without fluctuation."

Tanner raised an eyebrow. "And if it can't?"

"Then we improve it until it does."

The team wasted no time setting up the compressor with the reservoir tank. They secured the connections and carefully calibrated each joint to ensure the seals would hold under pressure. Matthew watched as the engineers tightened the last bolts, adjusting the valves to allow a controlled release of air, ready for their first test.

"Alright, everyone," Matthew called out, drawing the attention of the team. "This is it. We're going to push the compressor to seventy percent capacity for this test. If it holds, we'll increase gradually. Let's keep a close watch on all gauges, and be ready to release pressure at the first sign of fluctuation."

He nodded to Tanner, who stood by the main valve. Tanner shot him a cautious look but gave a small nod before he turned the valve, slowly allowing air to fill the reservoir. The gauges climbed steadily, the quiet hum of machinery filling the room. The entire team watched in tense anticipation as the pressure readings rose, every eye fixed on the equipment.

At sixty percent, a faint hiss escaped one of the seals on the reservoir. Tanner immediately gestured for a stop, and one of the engineers quickly closed the valve.

"Just a loose bolt," Tanner muttered, grabbing a wrench and tightening the joint before stepping back. "Should be fine now."

Matthew nodded, and they resumed, pushing the pressure higher. The readings climbed steadily—sixty-five, then seventy percent. At seventy-five, the gauge held steady, with no visible signs of strain on the system. A few of the engineers exchanged glances, some grinning, as relief washed over the room.

Matthew allowed himself a slight smile, but his focus remained intense. "Alright, let's push it to full capacity. I want to see this reservoir hold one hundred percent pressure before we move on to integrating the brake cylinders."

They adjusted the settings, and slowly, the gauge ticked upward. Eighty percent. Ninety. The compressor hummed, the steel and valves holding steady as the pressure continued to climb. When it finally reached one hundred percent, the team broke into applause, some engineers clapping Matthew on the back.

Tanner approached, his usual frown softened slightly. "I'll admit, that's impressive. Now, let's see if it can keep up under repeated use."

"Exactly," Matthew replied, his eyes glinting with determination. "The real test will be endurance. If this compressor can maintain consistent pressure for multiple cycles, then we're well on our way to making this air brake system a reality."

With the first major hurdle behind them, the team set to work on integrating the brake cylinders, ready to test how the pressure would distribute evenly along the entire system.

The team shifted gears, focusing on assembling the brake cylinders and connecting the intricate network of pipes that would run along the length of a train. Each cylinder, lined up on the worktable, would be tested individually before connecting to the full assembly. This phase was just as crucial as testing the compressor, as any inconsistency in pressure distribution could render the brakes unreliable.

Matthew approached the first set of cylinders, inspecting each connection and seal with a keen eye. "Let's connect these cylinders to the main line," he instructed, signaling two engineers to assist with the alignment. "We'll run a preliminary pressure test at fifty percent capacity. If there's any loss, we'll locate and address it before scaling up."

Tanner stood nearby, silently observing, his usual skepticism tempered by the previous test's success. "I'll monitor the gauge on the first cylinder," he offered, his voice steady. It was the first time Tanner volunteered, and Matthew appreciated the change in tone.

They began the test, filling the main line gradually as each cylinder responded to the air pressure with a smooth, steady hiss. Tanner's eyes flicked to the gauge, his brow furrowing as he observed the gradual rise in pressure. "Holding at fifty percent," he called out, glancing at Matthew.

"Perfect. Let's give it a few more seconds and check for any fluctuations," Matthew replied, holding his breath along with the team as they watched the readings remain stable.

Satisfied, Matthew instructed, "We'll move up to seventy-five percent on the next test, then integrate the remaining cylinders one by one."

The second round went just as smoothly, with the pressure maintaining consistency across the cylinders. Tanner's initial doubts seemed to fade, replaced by a genuine sense of respect as he observed the design hold up under rigorous conditions.

Once all cylinders were connected and the lines secured, Matthew called for a full-capacity test of the entire system. "This is where we see the air brake mechanism in action," he said, signaling the team to brace for the final test.

Tanner took his place beside Matthew, hands folded, eyes fixed on the gauge. "Here's hoping your theory holds, Matthew."

Matthew smirked, undeterred. "Only one way to find out." With a steady hand, he activated the system, watching as pressure built up along the line. The cylinders engaged, each one triggering the next in a cascading, synchronized movement.

At one hundred percent, the gauges held steady, and a ripple of pride and satisfaction passed through the team. The brake system had not only held up—it had surpassed their expectations. Engineers clapped each other on the back, and a few shook hands, knowing they had just contributed to a potentially groundbreaking advancement in railway safety.

Tanner let out a long exhale, then turned to Matthew. "Well, I suppose you've proven yourself, Matthew. It's not every day a young upstart turns theory into a working reality."

Matthew offered a firm nod. "It took a team to bring this to life, Mr. Tanner. But we're not done yet. We need to test it on an actual train."

Tanner cracked a rare smile. "One step at a time, Matthew. But I'd say you've earned your place here."
