James Greller was born in Brooklyn and his first image of a trolley began a lifelong interest in public transit of the City of New York and its past. He was educated at The School of Visual Art in New York and later New York University for his degree. He immediately was hired by National Broadcast Company. Later he formed his own production company in animation films with clients such as Sesame Street, Electric Company and Madison Avenue advertising agencies. He began writing books in 1987 when frustrated on how nothing was written on the world’s greatest traction city.

At this same time he was managing editor and co-creator of ELECTRICLINES magazine. With the magazine he hoped to promote the new innovations and tram revival in Europe as well as America’s golden past. He wanted to especially encourage the next generation of enthusiasts in this field. He changed his career to working in the transportation field beginning with the New York Metropolitan Agency, followed by the New Jersey Department of Transportation and later NJ Transit. At the beginning he was essential to the building of the Hudson/Bergen Light Rail, Riverine and Newark City Subway extensions. He championed the use of low-floor LRVs for Hudson/Bergen and Diesel LRVs for the new River. While at New Jersey Department of Transportation he created the unique PORTWAY - a truck container roadway, to and from the port and the many container rail heads. While at New Jersey Transit Line he pushed for the development of the double-deck cars for mainline commuter service.

Later working in the academic field at Voorhees Transportation School at Rutgers, he developed the Newark BRT system on several of its main city routes. This later became NJ Transits “GO BUS” BRT routes. In his latest consulting work, projects included the development of several light rail expansions in Houston Texas, the re-introduction of light rail to the Red Hook section of Brooklyn and bus BRT service to New York’s LaGuardia Airport. His last position before retirment was working for Hudson County in New Jersey. He still works as a consultant trying to improve the way people travel.
