Bring Earplugs...

Metra F40's 142 and 143 sit perched on the ends of their respective inbound trains at Ogilvie Transportation Centre in the Chicago Loop, ready to become the leading locomotives for mid day trains on the UP West and Northwest lines.

 

I should point out that not only were these units idling, they were SCREAMING.

 

Note to self: Wear ear plugs next time...
