Mike, he is building an SP P-4 light Pacific, specifically #2401

2401 was delivered with a 70-C tender, where 70 indicates 7000 gallon water capacity and C indicates a cylindrical (Vanderbilt) design. When rebuilt to P-4 it was likely given a 100-C tender, which is a 10000 gallon tender made by adding water courses to the 70-C. It is hard to tell which version of 100-C. SP added a digit after the tender type, such as 100-C-3, with the 3 indicating the specific type. There were minor differences in types - number of hatches, running board height, type of trucks, handrail shape. It is difficult to tell types even with photos, the SP had tender cards that listed the assigned locomotives, that would be the definite answer.

Edit- It looks like Roger Goldmann has a drawing for a 100-C rebuilt from a 70-C. The tender listed at the bottom of the page with number BK 833-12377 would be very close, and the tender truck CL 1269 would be a good truck under the tender.

Southern Pacific rostered a large and varied fleet of tenders to meet the needs of locomotive assignments. The bigger Pacific class locomotives usually featured a 10,000 or 12,000 gallon tender. Trucks could vary from 4 wheeled trucks to six wheeled trucks depending on the assignment. Another issue was the division assigned to and whether it was ATS territory or Block signal territory. The Automatic train stop ATS system required a special duplex induction coil on the tender and related control valves under the cab and inside the cab. A special air filter was also located under the cab to keep the delicate parts of the ATS system free from bits of grime known to give the system operating problems. The piping used in air systems years ago was notorious for internal corrosion and the related scum constantly becoming part of the moving air stream.

Tenders often changed to different locomotives based on what was ready to go when a locomotive was released from the shops. Some locomotives had several tender swaps in just the course of a single year. Sometimes only a couple of the digits needed to be changed on the back of a tender to keep the engine/tender numerals the same.

Backup headlamps on the rear of the tender could vary with the time frame of the photo. During the 1930 era, an Oliver lamp might be installed. later a Sacramento headlight might be found on the back of a tender and in the final years of service, a Pyle National was a very popular headlight on both ends of a SP steamer. Up until the time after WWII, a Keely can could often be found hanging from the tender frame ready for the doctoring of the next overheated plain journal bearing somewhere in the train.

Hi,
If I understood that correct than it must be the last two Drawings from the List of Roger Goldman be?
Is that correct?
Thanks!
