What Rogers locomotives are still around? Any operable? (doubt it) I believe the Paterson Mueseum is in the building that was the factory, or some sort of locomotive works. (Paterson had a few) I'm not 100% sure, though, it could of been some other sort of factory.
Paterson, NJ was home to Rogers Locomotive Works, Danforth & Cooke Locomotive and Machine Co., and Grant Locomotive Works.
Several Rogers locos still exist, including the famous War Between the States "General" in Kennesaw, GA (+ an other in Conyers, GA)
Others exist in Tuolume CA (4-6-0 Shay), KY RR Museum (L&N 4-6-2), Greenfield Village, MI (A&G 4-4-0), and Stillwater, MN (NP 4-6-0)
Rogers was in business from 1832 until purchased by ALCO in 1905. ALCO also made rotary plows in Paterson. Cooke started in 1852, purchased by ALCO in 1901. Grant the smallest of the three was formed in 1867 from the NJ Locomotive Co. quit after a fire in 1885.
