No Lights, No Air

We are sitting at the West Baltimore station after some technical problem resulted in a loss of lights and air.  Supposedly a technician will fix the problem . . . and after only a few minutes, he or she does.  Lights shine brightly now and the air is blowing with full force.  I hope whatever the problem though it was actually fixed.  We still have lots more stops before we arrive at our final destination.  And while arriving in the dark doesn't bother me, the train cars do get stifling when no air is circulating.
