New Jersey Transit has announced a desire to replace their fleet of Arrow III electric multiple unit (EMU) rail cars. The media reports than an RFP has been issued, but I see no evidence of it on the NJT website. NJT also stated a desire to have more EMU sets running on local routes. Today, locomotive-hauled train sets cover some or many local runs.
NJ Transit officials have put out requests for proposals to replace the aging cars with similar cars that are powered by motors in each car instead of being hauled by a locomotive, said Richard Sarles, NJ Transit executive director.
Electric-Multiple Unit cars (EMUs) are better for high-density rail lines with more stops, Sarles said.
“Certain areas need quick acceleration,” Sarles said.
I hope these new EMU cars incorporate at least two elements of SEPTA’s new “Silverliner V” EMU cars:
- the railfan window
- the railfan window seat
Here’s a Railway Age article from June 2006 that discusses the specs being drawn up for the Arrow III replacements, the Arrow IV, and related dual-mode multiple unit (DMMU) cars.
NJT’s 230 Arrow III electric multiple-units will be replaced with the Arrow IV. A sister vehicle to the Arrow IV will be a “DMMU” (dual-mode multiple unit), which will use the same basic architecture (carbody, trucks, propulsion control, a.c. traction motors, HVAC, door controls, cabs, etc.) as the EMU and share a common “A” car. Both vehicles will be configured as married pairs–the EMU as an A-B set, the DMMU as an A-D (for “diesel”) set. The EMU will have all 8 axles powered; its “B” car will carry pantographs, transformers, and other electrical gear. The DMMU’s “D” car will carry two diesel engine/generator sets but its axles will be non-powered.
