How does signal problems actually cause this?
Due to signal problems at E 180 St, the following service changes are in effect:
There are no trains between 96 St or 135 St and Wakefield-241 St.
There are no trains between Jackson Av and Dyre Av.
As an alternate, customers can use Bx39 or Bx41 buses.

It's being blamed for Con Ed problems.That makes more sense.Just signal problems shouldn't knock out service on the whole corridor.
