Two of Pennsylvania's best-known motorcoach operators, the Martz Group of Wilkes-Barre and Fullington Trailways of Clearfield, are marking 100-year anniversaries.

Martz was founded in Plymouth, Pa., in 1908 by Frank Martz, to transport miners. Today, the company is a multi-state, mulit-division enterprise, operating along the entire East Coast.

The business is in its third and fourth generations of family leadership, with Chairman Frank M. Henry celebrating 44 years at the helm this year. Son Scott Henry represents the fourth generation.

The company employs about 400 people and operates more than 270 motorcoaches.

In 1908, Emerson Fullington purchased a nine-passenger, horse-drawn surrey to transport residents to the local train station, founding Fullington Auto Bus Company.

With 450 employees and a fleet of 50 motorcoaches, 250 school buses and 10 limousines, the company is still run today by the Fullington family.

Emerson Fullington's great-granddaughter, Aerial Fullington Weisman, is president and CEO, and Michael L. Fullington, Emerson's great-grandson, is vice president and chief operating officer.

Martz was a founding member of the Trailways Transportation System, while Fullington was an early member of Trailways.

Martz is marking its anniversary by committing to operating a younger and more modern fleet than ever. It has reduced the average age of its fleet to five years. And this year it is adding 30 new MCI coaches.

The livery of the 15 new MCI J4500s and 15 MCI D4505 coaches includes a special Martz anniversary logo.

"As we celebrate our past and the rich history of our organization, we are looking forward to the future by introducing the latest models and features that MCI has to offer, including more passenger amenities and technological advances," said Craig Smith, CEO of Martz.

"We're proud to walk side by side down the road of transportation history with Martz," said Tom Sorrells, president and CEO of MCI, which is marking its own 75th anniversary this year.

Throughout this year, Fullington will feature special anniversary tours, celebrations, prizes and gifts, said Lory Fullington, vice president of charter, tour and school bus services.
