Steam & Excursion > Monday Museum Steam: The "Black Daylight"

Another locomotive this week from my 1992 trip to the National Museum of Transportation near St. Louis. Built during the war years, 4460 never got Daylight Colors. The museum said it served in both passenger and freight service, and pulled the last SP steam train in 1958.

What was the driver diameter size ?  I notice a different rod assembly on this loco compared to the GS 4/5 class . Were these limited to a lower max. operating speed in passemger service ? Thanks.

The War Production Board would not authorize SP to acquire more passenger engines, so the GS-6 class (SP 4460-4469) reverted to the GS-1/GS-2 driver diameter (73.5") and cylinder dimensions (27" x 30"), and were designated as "General Service" rather than "Golden State" locomotives.  Details here: https://www.steamlocomotive.com/locobase.php?country=USA&wheel=4-8-4&railroad=sp

It would be neat to see the SP 4449 and SP 4460 together if the 4449 somehow was able to make it to the St Louis area again on a special run. Highly doubtful however in today’s mainline operation world but I guess you never know.

Most of the Daylight engines were retired looking like this, even 4449 went to the deadline looking much like this.
