LAS VEGAS – As if a weekend in Las Vegas isn't wild enough for Southern Californians, a Nevada entrepreneur is about to add five more hours of party to either end.

After striking an agreement with Union Pacific Railroad last week, the Las Vegas Railway Express is one step closer to bringing to life the X Train, a luxurious "party train" complete with big screen TVs, recliners and two ultra lounges.

"The whole idea is when you get on a train, you feel like you're in Las Vegas," said Michael Barron, president and CEO of the $100 million venture that hopes to launch its maiden voyage on New Year's Eve 2013. "It's essentially a nightclub on wheels."
