Westbound Canadian Pacific freight train with former Soo Line railroad locomotives arriving in Franklin Park Illinois. May 2008., a photo by Eddie from Chicago on Flickr.
Franklin Park Illinois, is a great place for local Chicago area railfan photographers to visit.
The former Milwaukee Road mainline owned by Canadian Pacific, as well as the nearby Indiana Harbor Belt and Canadian National railroad lines, see plenty of action in this area 24 -7.
However....if you are one of those people who HATE being stopped by long and slow freight trains, You might want to avoid the area if possible. Maybe you should hope for a raised railroad crossing gate between train times.
