Still mulling over intergenerational conflict as I am, at least I have some good news about Chicago's infrastructure:
[T]he CTA today announced that Purple Express trains in the Loop will resume operation traveling clockwise on Monday, December 29. In April 2007, when three-track operation began at both the Belmont and Fullerton stations, the CTA moved Purple Express trains to travel in the same direction as Brown Line trains (counter-clockwise around the Loop) to supplement Brown Line service and help ease congestion in the Loop during three-track operation.
With fewer Brown Line trains in service as a result of three track, Purple Express trains were rerouted in the Loop to mimic Brown Line service and help customers more quickly exit the downtown area.
This won't make the ride any warmer, but it will make it faster.
Forgot to mention, it won't make it any cheaper , either.
