Question: Acela Express is the flagship service of what major transportation hub in Newark, new Jersey?

<P0-S0> The Acela Express ( ; colloquially abbreviated to Acela) is Amtrak's flagship service along the Northeast Corridor (NEC) in the Northeast United States between Washington, D.C. and Boston via 14 intermediate stops including Baltimore, Philadelphia, and New York City. <P0-S1>  The route contains segments of high-speed rail, and Acela Express trains are the fastest trainsets in the Americas; they attain 150 mph on 28 mile of the route. <SEP> <P1-S0> Pennsylvania Station (also known as Newark Penn Station) is a major transportation hub in Newark, New Jersey. <P1-S1>  Located at Raymond Plaza, between Market Street and Raymond Boulevard, Newark Penn Station is served by multiple rail and bus carriers. <P1-S2>  The rail carriers include Newark Light Rail, New Jersey Transit (3 commuter rail lines), the PATH rapid transit system to Manhattan, and Amtrak (11 lines including the Acela Express). <P1-S3>  National bus carries include Greyhound, Peter Pan and Trailways. <P1-S4>  Local and regional bus carriers include NJ Transit and ONE (Orange-Newark-Elizabeth), with 31 and 2 routes respectively. <SEP> <P2-S0> The JetTrain was an experimental high-speed passenger train created by Bombardier Transportation in an attempt to make European-style high-speed service more financially appealing to passenger railways in North America. <P2-S1>  It was expected to use the same LRC-derived tilting carriages as the Acela Express trains that Bombardier built for Amtrak in the 1990s and a similar locomotive. <P2-S2>  Unlike the Acela, powered electrically by overhead lines (as are most other high-speed trains), the JetTrain was designed to use petroleum-based fuel to power a diesel engine and multiple turboshaft engines for higher speeds. <SEP> <P3-S0> The Wayne Route 23 Transit Center is a mass transportation hub located in Wayne, New Jersey, USA. <P3-S1>  Operated by NJ Transit, the complex consists of two major components. <P3-S2>  One is a bus terminal that provides service to Port Authority Bus Terminal, Newark Penn Station, and intermediate points in the surrounding area. <P3-S3>  The other is a train platform that is connected to the Montclair-Boonton Line and offers service to Hoboken Terminal, connecting service to New York Penn Station, and local service to points between Montclair State University and Hackettstown. <P3-S4>  It is located off of the southbound lanes of New Jersey Route 23 on West Belt Road, near the interchange where Route 23, I-80, and US 46 meet, across from the Willowbrook Mall. <P3-S5>  The station opened in January 2008 and has 1,000 parking spaces. <P3-S6>  New Jersey Transit intends for this combined rail and bus station to become an "interceptor station," that will help relieve the habitual congestion at the West Belt Road Interchange, where the three major highways meet. <P3-S7>  In addition, the construction of the station was meant to also ease the congestion at what was then Route 23 Park & Ride, a bus depot on Route 23 North that has since been renamed Mother's Park & Ride, and the Willowbrook Mall Park & Ride; the now-Mother's site had limited parking while NJT was having trouble with overfull parking areas at Willowbrook.
