The Wisconsin & Southern Railroad (WSOR) is noteably one of the finest regional railroads to railfan on with its numerous daily freight operations! The appearance of its locomotive fleet makes is a must to capture! I was fortunate enough to catch their T4 job rolling through Whitewater Wi. on 12/22/10 on their Waukesha Subdivision. On this particular railroad, You will be able to catch passenger & business specials with their ABA E9 units & business cars as well as periodic host to steam trains such as the SooLine 1003 for varios events! I'll add a few more of their videos here in time with much more info! Until then! Enjoy!
