The south street signal bridge is in the process of being replaced by a new 
one.If anybody can help i need some help understanding the signal bridge that 
is going in.the new bridge will have three rows of light instead of two as if 
itcontrolling three seperate tracks.also west of the yard entrance and the 
cross over there will be a new signal bridge and it going to have the same 
lights as the other one. can anyone understand why three lights for only two 
track mainline.i have a picture i will post in the photo section
