NEL. It uses pantograph (which reduces friction and increases
speed), and has a Alstom ONIX IGBT-VVVF, which means like
other VVVF systems (GTO-VVVF and IGBT-VVVF), it can easily beat
anything using a GTO thyristor.
Perhaps the most interesting thing VVVF inverters has brought
about is the wonderful noises it can make as compared to a
thyristor system (compare a C751B sound with C151 sound, there is
something like a howl in the C751B), especially if its a Siemens
GTO-VVVF, whereby a piano sound is made.
Can post a picture of NEL's pantograph?
Didn't expect that Singapore got use pantograph :)
Coz i think use third-rail looks nicer compared to
pantograph.
