The Jersey Arrow is a type of electric multiple unit (EMU) railcar developed for the Pennsylvania Railroad, and used through successive commuter operators in New Jersey, through to New Jersey Transit. Three models were built but only the third is in use today. The series is similar to SEPTA's Silverliner series, but include center doors among other differences in details.

Arrow I [edit]
The first series of Arrows (known as PRR MP85s) were built in 1968-69 by the St. Louis Car Company; 35 were built and purchased by the New Jersey Department of Transportation.[1] These cars were initially numbered 100-134. These cars were built with higher capacity 3-2 seating which caused grumbling by the passengers at that time.
These cars bear some resemblance to the Silverliner III also produced by St. Louis Car company at the time, including a unique numberboard area. However, these cars are very different mechanically. They featured diamond shaped "Stemman" pantographs, round windows, center doors, and a different body shape.
Car 107 caught fire and was scrapped. During 1975, the Arrow Is were rebuilt to be compatible with the newly arrived Arrow IIs. As they were rebuilt, they were renumbered 500-533 (accounting for the loss of 107).
A further renumbering of the Arrow Is to 1200-1233 was planned, however this was never implemented as the Arrow Is were instead retired. The Arrow Is were phased out and stored as additional Arrow IIIs arrived from General Electric. All cars were stored out of service in the late 1970s due to reliability issues with their Westinghouse propulsion equipment.
They were converted into locomotive-hauled coaches called Comet IBs in 1987-89 by Morrison Knudsen.[1] The rebuilt Comet IBs remained in service until late 2008, with some now leased or sold.
Arrow II [edit]
In 1974, the General Electric and the Avco produced 70 Arrow II cars in the married pair format. The Arrow IIs were numbered 534-603. The Arrow IIs were purchased specifically to replace the ancient PRR MP54s, which were slowly phased out of New Jersey service in late 1977. General Electric was the prime contractor for the order and bought stainless steel body shells fabricated by Avco and before assembling the railcars in Erie, PA.
The Arrow IIs were constructed following the production of SEPTA's single unit Silverliner IVs, but prior to the Married Pair Silverliner IV units.[2] Indeed, the Arrow II and the Silverliner IV share the same body shell, cab corner air scoops and single armed Faively pantographs, with the primary differences being the shorter Air intake hump on the roof, lack of dynamic brakes, and the inclusion of the high-level center door as on the Arrow I.
One important feature was the 2-2 seating, which was a result of passenger complaint over the 3-2 seating on the Arrow I. The Arrow IIs also featured a toilet in the B-car.
In service, the Arrow IIs were leased to Amtrak and MARC in the late 70s, with units 590-591 becoming destroyed in a collision early in their MARC service. Arrow IIs could be found running Harrisburg bound trains, Off-peak Clockers, and electrified commuter service in Maryland, where they bumped the last operating MP54s from service.
Upon the formation of NJ Transit, the Arrow IIs were called back to New Jersey, rebuilt to operate on the former Delaware Lackawanna & Western Hoboken commuter lines. As they were rebuilt, they were renumbered to 1234-1303. The Arrow IIs ran on the Hoboken division until 1997, when the decision was made to retire them due to rotting floors and holes in the roofs. Most were scrapped in 2001. One pair remains (however split) as part of SEPTA's wire inspection train.[1]
Arrow III [edit]
The Arrow IIIs were built between 1976 and 1979 by General Electric and Avco[3] in the same fashion as the Arrow II's. They consist of 200 cars built as married pairs (1334–1533) and 30 single cars (1304–1333).[1] These cars were initially ordered as part of a plan to rehabilitate the NJ DOT (Later NJ Transit's) Hoboken division, converting the 3,000 volt DC system to a 25 Kv 60 Hz AC system. However, due to the retirement of the Arrow I MUs, and the Arrow IIs frequently being leased to Amtrak and MARC, as well as delays to the rehabilitation of the Hoboken electrification, the Arrow IIIs were assigned to the former Penn Central electrified lines instead[1]. As a result, the Arrow IIs and only a portion of the Arrow III fleet were devoted to the Hoboken division when the electrification work was finally finished in 1984, with the remaining Arrow IIIs being assigned as the only MUs in service on the Northeast Corridor and North Jersey Coast Line[1]. Due to the lack of an automatic transformer tap changer, the Arrow III's cannot switch between line voltages while in service. To prevent confusion a triangular orange sticker with the current voltage the unit is set to is affixed under the front window, "12k" for the Newark Division and "25k" for the Hoboken Division. After the North Jersey Coast Line was changed to 25kV south of Matawan, MU service to Long Branch was replaced by push-pull trainsets only.
Similar to the Silverliner IV and Arrow II, the Arrow IIIs share a similar body shell. However, the Arrow IIIs have some prominent differences, notably the two small air intake blisters (as opposed to the large humps on prior models). The Arrow IIIs also featured the twin arm Stemman pantographs shared by the Arrow Is and built by the United Knitting Machine corporation. The large central air scoop over the center of the roof on each cab end is the final major spotting feature. The Arrow IIIs saw the return of 3-2 seating.
The Arrow III's were given a mid-life overhaul between 1992 and 1995 by ABB. The rebuild replaced the original DC propulsion system with a new solid state AC system that also included higher power traction motors with a total of about 375hp per two axle truck. The increased power per motor allowed for motors to be eliminated from the truck located under the pantograph in each of the married pairs, reducing the number of powered axles per pair to 6 although raising horsepower to 1150. Single units retained all 4 powered axles with a total of 750hp. After the rebuild was completed problems were encountered with both traction motor and axle bearing overheating which lowered the maximum permitted speed in service to 90mph from 100 and then ultimately to 80mph as the problems persisted. In 2011 a single arm Schunk type pantograph was fitted to Arrow III #1463 replacing the original twin arm Stemman. By 2013 six additional units had been fitted with the new panthgraph.
As of 2013 New Jersey Transit uses Arrow IIIs extensively on the Gladstone Branch (Hoboken to Gladstone), on the Princeton Branch (Princeton Junction to Princeton University), on the North Jersey Coast Line (New York/Rahway to Matawan, and the Northeast Corridor line (New York to Trenton).[1]
