It was able to compete with the Rapid Transit Series, Flxible Metro, Gillig Phantom and the Orion I in the early 1980s. ModelsThe Transliner was available in a wide variety of body styles. The Transliners could be ordered in 26', 30', 35', 40', and 60' lengths. Standard (high), completely low, or semi-low (with steps to access the rear section after the rear doors) floors were available. NeoPlan offered a variety of engines, both diesel and CNG fueled. Depending upon the model, Detroit Diesel 40 or 50 series or the 6V92TA; Cummins ISM, C-series, or ISL; or CAT C-9 engines could also be had. Most Transliners featured Allison B400 or B500 "World Transmissions". However, ZF (4HP590) and Voith transmissions were also available on some models.
HistoryIn late 1983 through 1985, Neoplan delivered an order for over 1000 buses for the state of Pennsylvania. By 1989, the largest transportation network in Pennsylvania, SEPTA, had 1092 Neoplan AN440s in service. However over the years as they were heavily replaced mainly by New Flyer Low Floor buses, that were placed in service since between 2001 and 2006, While the remaining 35 Neoplan AN440s (EZ models) were sent to the SEPTA Frankford Depot, following after the retirement of the 1978 AM General Trolleybuses that retire in 2006, as they served as the temporary replacement, they were retired on June 20, 2008, following after the final delivery of the New Flyer trolleybuses was completed. SEPTA ordered 155 Neoplan AN460s from 1998-2000 to replace their aging Volvo B10M articulated buses and about 60 AN460 high floor buses are in service until 2013, they were being replaced by Novabus LFS Artic articulated buses, as of 2016, after delivering the last remaining set of Novabus Artics, all of the remaining AN460 buses were retired. In the 1980s, WMATA, also known as Metro, and PAT Port Authority Transit in Pittsburgh, Pennsylvania complained about frame problems with their Neoplan coaches. However, today, they both run new Neoplan buses — WMATA with the AN460, a 60-foot articulated version, and PAT with AN460s and AN440LFs, the low floor version of these buses. However, the AN440 and AN460 models ordered by the San Francisco Municipal Railway proved troublesome. Among the problems were insufficient, excessively noisy cooling fans (sounds reached up to 90 dB), faulty transmissions, maintenance intensive brake systems (needing service every 5,000 miles), and cracking frames. The problems were compounded when Neoplan eventually refused to fix the problems, instead choosing to repossess the remaining spare parts and abandon its overhaul yard located in San Francisco.[1][2][3] SpecificationsConstructionSelf-supporting monocoque steel construction made of seamless square steel tubes, electrically welded.

The bus networks that have or have had them in service are MBTA in Boston, Massachusetts; SEPTA in Philadelphia, Pennsylvania; WMATA in Washington, DC; ABQ RIDE in Albuquerque, New Mexico and LACMTA in Los Angeles, California.{{Citation needed|date=December 2007}} San Francisco Municipal Railway (SF MUNI) ordered Neoplan AN440s and AN460s to replace their aging bus fleet during 2001-2004, but they are unique in that they have rear windows, with the air conditioning unit mounted on the roof. Bi-State Development Agency, dba Metro, has a small fleet of Neoplan Buses for its MetroBus service, and since March 30, 2009, has retired them. See also{{Portal|Buses}}
