The sun hung low on the horizon. With quick shifting from the beast under him as it pawed the dry ground pulling plums of dust into the air before settling the hoof back down. A soft nicker came as the pale head of his horse drew up flicker it's ears around. Leaning only a bit forward he gave the beast a few pats in reply. "You'll be fine, girl. Not much longer." His baritone voice whispered load enough for his horse to hear.
His gaze remained on the tracks below. Soon, his gang would be racing down to intercept with the train scheduled to pass through. With a sharp whistle that cut through the air he waited for a return call getting several as he raised his green bandana up to cover his face. With a sharp heel dig and a 'Yah' shout the beast sprung forward with stomps throwing up dirt. The pounding of hooves grew as his gang raced after him adding to the tempo of heavy breathing snorts and hoofbeats. The shrill sound of steam rang out over powering the thunder of hooves as the train appeared in view. With a few more heel digs the horses ate up the ground gaining on the caboose of the train.
Standing with a rifle ready in his hands was an officer of the law. Catching sight of the gang he quickly brought it up only for a shot to ring out. He fell forwards, a dark spot growing at the front of his chest, off of the train hitting ground in a broken roll. Soon, the gang reached the caboose each taking a turn jumping to the platform leaving one to gather the horses back up. With guns at the ready they moved through the car as the gang entered the one holding passengers.
"Ladies and Gentlemen. If you would kindly stay seated and quiet we will be done soon." The leader stated pacing slowly down the aisle glancing right to left with gun raise upwards. "Lenny, Jacob, take control of the engine. Marvin, Henry, John, why don't we relieve these lovely people of all valuables and bills." He said gently watching as his men went about holding a sack as gems, coins, and other things were tossed into it.
A lurch came causing panic to be heard from the passengers as they jerked in the seats. Only Henry seemed to have trouble keeping his feet as he fell face first into he padded floor. A flurry of movement came as one of the passengers lunged after the gun that was loosened to quickly taking aim at the downed man. The leader raised a brow at the valor the young man held doing such an act knowing he was outgunned by three. The young man's eyes twitched from each gang member as he kept the gun aimed at the downed man even with the slight shake at the tip of the barrel.
"Now, son, why would you do something so reckless?" the leader asked with a tone of concern his gun still held upwards to the ceiling. "Put the gun down, take your seat back and no harm will come to you." The young man shook his head keeping the gun tightly within his grip with his eyes settling on the leader. The leader gave a sigh of mock regret. "Damn son, that wasn't a wise choice." With a reflex of a rattle snake the leader took aim and shot. Screams came from the sudden sound as the young man's body thumped heavily to the floor. "Now if any of you don't want to join that young man please do remain in your seats. We will be leaving shortly."
Henry picked up his gun again with the bag of loot to continue gathering items not letting his eyes turn to his leader knowing he broke a rule of the gang. Never let another take your gun. Once the train came to a full stop the members ran out of the car spotting their horses. With years of being in the saddle they quickly left, the sound of thundering hooves growing distant.
