A/N You guys were all so wonderful and kind to me, I decided to give this another shot. For some reason I'm more nervous this time. Dropping me a review to say anything would really mean the world. I'm not one for begging for them, but knowing you would like me to continue and see where this goes, would make my nervous day.

Another small thing, I have this already written. So like last time, updates will be frequent. Let me know how often suits you. Daily or every other day, I don't mind either way. There are only 7 chapters. Thanks again.x

The same disclaimer applies as before. I own nothing except the mistakes, and there are bound to be some lurking about.

"Quick you guys, cut him off from the other end." Beckett shouted from the platform, pointing in the direction that she wanted Ryan and Esposito to head.

Castle was quickly on her coat tails. He was being careful to stay out of the direct line of fire, so to speak. He loved this part; the adrenalin rush was like nothing else he'd ever experienced. This part never got old, scary some times, but never old.

They had been chasing the perp down the platform at Pen Station for the last five minutes. What turned out to be a simple burglary had gone horribly wrong. The owner had unexpectedly returned from out of town and wound up with a knife in his belly and subsequently on Lanie's table.

They'd caught a break when he tried to fence some of the goods to an undercover cop. He'd made a run for it and was currently trying to dodge NYPD's finest through one of the busiest train stations.

"Move, move." Beckett commanded, as she bobbed her way through the crowd. "Come on Castle, keep up." She turned quickly to glance over her shoulder to find Castle huffing and puffing trying to keep up with her. She couldn't help but laugh at her partner as he tried to pick up the pace.

He was like a whippet. Weaving and darting in and out of the crowd. The distance between the cops and him was now getting greater. It wasn't that Beckett couldn't keep up; he was just so damned fast and small. Although she'd healed from the shooting, she still wasn't back to complete fitness yet. Every day she grew stronger and more determined.

"He's heading for the Amtrak train." Esposito yelled over in Beckett's direction.

Ryan and Esposito picked up their heels and ran faster, trying to get to him before he reached the train. It seemed that Stop, NYPD didn't have the same effect as it used to. He continued running and the passing travellers barely disbursed enough to give them a clean run at him.

"No, No." bellowed Beckett. She watched as he jumped in front of some passengers, squeezing his way onto the train. She ran parallel with it, watching through the panes of glass as he made his way through the carriages.

"Quick, this way." Castle instructed as he pulled on her arm. A swift hop and he and Beckett were now on the inside of the train, chasing after him.

"Stay behind me Castle." Beckett insisted, her gun now drawn, "Castle, do you hear me?" she asked him.

Castle was in fact right behind her. So much so that her behind was all he could see. The way those tight jeans accentuated every curve of her was going to be his undoing.

"Huh? Yes, I'm right here." He replied, inching closer to her.

Her eyes were busily scanning the seats and open sleeping compartments as eager patrons got comfortable. There were far too many people to be able to get a positive id as to his whereabouts now.

"Damn it." Beckett groaned out in frustration, "Where the hell is he?"

As they continued to walk through the train, an announcement came over the PA system that the train would be departing momentarily.

"Castle, we have to get off this thing." she instructed, now pushing her way towards the first available door.

"There he is, over in the next carriage." Castle detected, thrusting Beckett forward.

They both ran the last remaining distance to the automatic door, only to see him jump through it at the last second. He had a smug grin on his face as the doors closed and locked behind him.

Both Beckett and Castle tried frantically to open the door as they felt the train moving.

"Beckett, we're moving." Castle noted, giving her a wide eyed look.

"Good observation skills there Sherlock." She replied sarcastically. She did not want to be stuck on a train going god knows where.

That smug grin was soon washed off the perp's face as Esposito grabbed him from behind and slapped the cuffs on him. "Where the hell do ya think you were going, huh?" he asked, tightening the cuffs to an uncomfortable position.

With his hand placed on his back, he etched him forward to the waiting uniforms. They could transport him back to the precinct and start the booking procedure.

"Where did Beckett and Castle go?" Ryan asked, looking over to his partner puzzled.

"What the hell bro!" Esposito exclaimed. His arms were outstretched in front of him, giving Ryan a look of I don't believe it as both of them saw Castle and Beckett disappear along with the train out of the station.

"What do we do now?" Castle asked, staring at a frustrated Beckett. Her hands were still on the glass of the door, banging it as if it was magically going to open again.

Beckett stood there and ran her hands through her hair. She was sweeping her head from side to side, trying to think of what her next move should be.

"Beckett?" Castle asked again.

"Shut up Castle, I'm thinking here." She snapped at him. "I'm trying to get us out of this mess you seem to have gotten us into."

"Me?" he asked surprised, "You think this is my fault?" he questioned.

Beckett stopped scrutinizing her surroundings and looked at him. "Well, you're the one who pulled us on this damned train Castle." She pointed out to him.

"True," he conceded, "But only because the bad guy did the same. I had no idea this thing was about to depart. From what I could see, the boys arrested him and surely that is all that matters?" he asked.

"Of course it is," she puffed out, "but being stuck in this thing was not part of the job description, ya know?" Her voice was a little softer now. She knew Castle meant well and if she was totally honest with herself, it was actually quick thinking on his part to hop the train as the last minute.

"Well, we will just have to get off at the next stop. Right?" Castle enquired.

"I have to find someone to talk to, see if they can get us off this train."

Beckett continued to look in both directions again as she began walking. "I have to find someone." She repeated to herself.

"Kate." Castle called out, watching as she started to walk away from him.

"What Castle?" she replied, firing her head in his direction.

"How bad can it be? We wait a few hours and before you know it, we'll be back at the precinct."

Beckett shot him look that said he'd better be right or there'd be trouble. Like the good faithful lap dog he was, Castle immediately stepped beside his master and followed her.

It wasn't long until Beckett found a young conductor. He was currently helping a family into their compartment. She waited until he was finished before approaching him.

"Can I help you Ma'am, Sir." He asked politely, looking at them both smiling.

"Detective Beckett NYPD." She announced firmly, her badge almost sticking in his face.

The young man had a look of concern on his face now, the smile long gone. "Is there something wrong?" he asked.

"Yes, yes there is." Castle confirmed.

Brian the employee listened captivated as Beckett relayed the turn of events that lead them to be here at this moment.

"So you see," Beckett began, "We really need to get off this train now. Where is the next stop?" She enquired.

"Normally it stops in Chicago, but seeing as there are no passengers getting off or on there; the next stop is the final destination." He answered.

"And that would be where exactly? Beckett pressed.

"Los Angeles."

"What!" Both Castle and Beckett answered him the same time as they looked at each other.

Castle sucked in his breath and pressed his lips together, trying to stop the laugh that was threatening to escape.

"How bad can it be?" Beckett repeated his earlier question back at him, "Oh pretty bad Castle, pretty bad." She answered herself.

Well there ya go, first chapter up. Thoughts, would you like to see more?
