Does anyone remember the quality of the Neoplan AN440 series? They were made in both T-drive and V-drive configurations. The very first Neoplan AN440s to show up in the USA were ordered by Atlanta, GA's MARTA, and these (of the V-drive configuration) used Detroit Diesel 8V71N engines and Allison V730 transmissions. That was in 1981, the year Neoplan USA was established. In 1982, SEPTA of Philadelphia, PA signed a multi-year contract with Neoplan USA to deliver 1000 buses between 1982-89. They were of the T-drive configuration, and so were equipped with Detroit Diesel 6V92TA engines and Allison HT740 transmissions (from 1982-83; the 1984-85 models used the slightly improved Allison HT747 transmissions, and the 1986-89 models used ZF 4HP590 transmissions). In 1983, LACMTA (then SCRTD) of Los Angeles, CA, took delivery of 415 AN440A-T buses with the same powertrain as the SEPTA Neoplans (the Detroit Diesel 6V92TA and Allison HT747, for units #3300-3689; #3690-3714, from 1984, used the Allison HT748 ATEC). Four years later, they would order 90 AN440A-V units, #1100-1189, with the same Detroit Diesel 6V92TA DDEC engine, but being a V-drive layout, used the Allison V731 ATEC transmission. In 1986, MTA of Baltimore, MD, took delivery of just 10 AN440A-T models, ID's #3701-3710. All 10 had Detroit Diesel 6V92TA engines, but the first 5 units, #3701-3705, used Allison HT747 transmissions while the second part of the order, #3706-3710, used Voith D863.2 transmissions (which was usually only available if the engine were a Cummins L10). In 1991, Jacksonville Transit of Jacksonville, FL, took delivery of 20 AN440A-V models, ID's #9101-9120, with the same powertrain as the Los Angeles 1100 series Neoplans. It should also be known that Neoplan initially supplied its own axles (both front and rear) before switching to Rockwell (later Meritor) and ZF axles. I wonder what the rear end ratios are as to the Neoplan axles used in the 1980s. ~Ben
