Those LEDs are a need especially on a line like the were trains randomly switch northern terminals Parkchester or Pelham Bay daily. That system helps riders know what train is express/local much less on a SMEE R62A equipment. If a local rider of the line has common sense to know the difference between the circle & diamond distiction then those LEDs are worthless, but for anyone else who don't ride the on a normal basis then those lights are a need for a better understanding. I feel they need to eventually rearrange several of the R62As sets in numerical order, like the 1800s that currently run the should go to the and once the 2100s are full width then they can end up on the displacing the 1800s. If the case is that Westchester doesn't know how to fix the LED lights which I don't think thats likely the case then it is what it is and they could remove them if they want, the is a very demanding subway line and certain components on the rolling stock serving the line can crap out, but they are usefull for riders who need to go local or express on the .
