Some interesting notes...
All 2290 series Orions have Detroit Series 50 engines. Orions 2120 2124 are CNG buses. 2211, 2074, and 2275 also have the series 50 engines.
NovaBus 2600 2699 were in the 1996 Olympics in Atlanta GA. Coach 2600 was wrecked there, and replaced very fast by Novabus. It has things in it that are unique.
Orions 2016, 2067, 2072, 2090 and 2111 were lost due to fires.
Information has it that we may also have the last Nova Bus Classic delivered in the USA.
Neoplan Low Floor 5019 Destroyed by fire.
Gillig Advantage Low Floors...
5201–5365
2003 (Detroit Series 50 / Allison 5 speed)
5371–5376 2005 (diesel/electric hybrids)
5401–5460 2005 (Detroit Series 50 / ZF 5 speed)
5501–5590 2006 (Cummins ISM / Voith 4 speed)
5600-5679 2009 (Cummins ISM / Voith 4 speed)
Note: 5290 was damaged after a dump truck slammed into the vehicle as it was picking up passengers. It has since been rebuilt and repainted, to fit into the 55XX paint scheme.

There is a new
fleet of 56XX buses with different color schemes as well. The Colors are Darker
and Richer than previous 55XX spring Colors. The 56XX are more like Fall colors.
On the 56XX the exhaust pipe is different than the standard pipe found on
previous Port Authority buses with the exception of #5588 being the First
gillig Low Floor to sport the New Style. 56XX buses are equipped with Diesel
Particle Filters, L.E.D. interior lights, hand rail on driver-side wheel well,
full glass doors, different flooring and many other smaller features.
Neoplan 60-foot articulated notes...
3051–3075
(Detroit Series 50 / Allison B500R)
These busses have commuter seats like on the Metroliners, and are used on
the 68J and 61C routes respectively
3101–3125 (Detroit Series 60 / Allison B500R)
These buses have regular, transit seating used on the Martin Luther King
Jr. East Busway, 71D, and occasionally, the 61A, 81B & 86B respectively
These are the last Neoplan USA buses ever manufactured.
Differences between Flxible orders at Port Authority...
There were two distinct orders, one was the main order, which were buses 2300–2449 in 1993, then the option order, which covers all the rest.
The original order had the Luminator ODK installed in front of operator, mounted in the bulkhead. The option order had Luminator ODK mounted to the left of operator on the electrical access door.
The original order had vinyl blue seats with single forward-facing seats on the right side of the bus. No further buses vinyl seats or with single forward-facing seats were ordered. The option order marked the beginning of cloth seats and double, forward-facing seats becoming the standard throughout on Port Authority buses.
The original order had a Voith 3-speed transmission, while the option order had Allison 3-speed.
Various minor differences: the option order makes a whining sound that is not present in original order; the option order has transparent rear doors while the original order has glass on the top only; interior coach number font is different; the box behind the operator's seat on the option order is smaller, allowing the seat to slide back farther.
Originally ordered 150, but Flxible ceased operations, thus the gaps in the 1995 order.
2446 was destroyed when it rear-ended a parked 18-wheeler. 2550 and 2581 were destroyed when they crashed into each other in a January 1996 snowstorm on the East Busway. This accident resulted in the death of the operator of 2581, the termination of the operator of 2550 and many injuries, but no passengers died.

Other Notes...
Nova 2654 Wrecked, but it has been revived! In Blue!
Some of these wrecked buses can be found on the End of the Line Page.
Neoplan 3500 3864 were part of the Penn-Dot order for the whole state of Pennsylvania. They were affectionately known as "Pennliners". They are all retired now.
