Nostalgia & History > Does anyone recognize this locomotive?

Does this locomotive look familiar to anyone? The photo is on a post card, using Kodak photo paper, so that puts the card after 1950, but it could be a reprint. However, the clothing of the people standing around kind of looks like the 1950s or 60s, I think. I can't quite make out the letters on the side of the tender. Any help identifying the scene would be greatly appreciated.

Judging from those domes, one of those Russian decapods that never made it to the Soviet Union. That motley assortment of passenger equipment is a mystery, though.

This is the Marquette and Huron Mountain Railroad operation in Michigan. Former Lake Superior and Ishpeming #19, a 2-8-0. In later years, it spent time on display at the Grand Canyon Railway. Its sisters survive in various locations and statuses: #18, formerly operated on the Grand Canyon and is now in operation on the Rio Grand Scenic Railway. #22 is at the Mid-Continent Railway Museum and also #23 is in New York State on the property of the Catskill Mountain Railroad (Empire State Railway Museum)

A bigger sister is , #29 is still on the Grand Canyon RR, and two of the biggest of the LS&I Consolidations are in operable condition with one being on the Western Maryland Railway as 734 (former LS&I #34) and Jerry Jacobson has the former LS&I #33, former on the Ohio Central. I believe #35 is at Greenbay?

Thanks for the help. I appreciate it.
