The Arrow IIIs originally had single arm pantographs. The Faively or whatever pantographs that GE installed on the Silverliner IIs, IIIs, Arrow IIs, Silverliner IVs, and Arrow IIIs as well as possibly the E60CPs had a tendancy to be extremely unforgiving on wire defects. Presumably NJT encountered a whole bunch of wire downings before they decided to replace the A3's pantographs with a more forgiving dual arm design, possibly in 1991. Since the Arrow IIs were on their way out back then they wouldn't have had their pantographs changed. SEPTA is now changing the Silverliner IV pantographs to a more forgiving design single arm pantograph for the same reason NJT changed the A3's pans. |
