UP 5504         
Eastbound manifest blasts out of the east portal of tunnel 28. The metal shed above once housed a curtain used in the past for forcing smoky air in a reverse direction of the train so it would not overheat. This tunnel being over 3200 long, the curtain was supposedly timed to open in time for the train to clear.
