The Nevada State Railroad museum will be hosting an event titled the "Great Western Steam Up" from July 1 to July 4, 2022.

Along with their own extensive collection of railroad items, which include several operable steam locomotives, there will be 8 (at the time of this posting) guest locomotives visiting the museum.
Visiting locos include:
Virginia & Truckee 11 "Reno", a 4-4-0 built by M. Baird & Co. in 1872.
The "Reno" resides on the Virginia & Truckee Railroad in Virginia City, Nevada, and is currently a non-operational display piece.
Virginia & Truckee 21, a 2-4-0 built by Baldwin in 1875.
21 is based at the California State Railroad Museum in Sacramento, and is a non-operational display.
Virginia & Truckee 12, a 4-4-0 built by M. Baird & Co. in 1873.
Also at the CA State RR Museum, also a non-operable display.
Bluestone Mining & Smelting 1, a 2 truck Heisler built by the Heisler Locomotive Works in 1916.
It normally resides at the Roots of Motive Power museum in Willits, California, and is fully operational!
Nevada County Narrow Gauge 5, a narrow gauge 2-6-0 built by Baldwin in 1875.
5's normal residence is the Nevada County Narrow Gauge Railroad Museum in Nevada City, California.
5 is a non-operable display.
Southern Pacific 18 "Slim Princess", a narrow gauge 4-6-0 built by Baldwin in 1911.
Normally residing at the Carson & Colorado Railway Society (Eastern Sierra Museum) in Independence, California, 18 is fully operational!
Cortez Mines Limited 1 "Ann Marie", a narrow gauge 0-4-0T* built by H.K. Porter in 1890.
Under private ownership and based in Hayward, California, 1 is fully opeartional!
Santa Cruz Portland Cement 2, an 0-4-0T built by H.K. Porter in 1909.
Normally based on the Placerville & Sacramento Valley Railroad in Folsom**, California, 2 is fully operational!
*the "T" in a wheel arrangement stands for "tank", as in a tank engine, which means the locomotive carries its fuel and water supply on board, with no tender.
**yes, the Folsom of "Folsom Prison Blues" fame. I actually checked on that while typing this post, and there's actually a Folsom Prison Museum, no doubt with a looped soundtrack of Johnny Cash's hit playing everywhere. Because why wouldn't it be?
Anyway, the "Great Western Steam Up" sounds like it'll be a super awesome event, with the rare occurrence of several locomotives, many of which are operational, visiting a location together, something that's only happened a few times before, to my knowledge (though it's more common in Britain, with smaller locos and less distance to travel).
