General Information
RPO
Postal-baggage cars
Postal-baggage cars were used in postal storage service when needed.
SP's last RPO
SP did not run any RPOs after 1967.
Vanishing Vistas postcard JT-1697 shows the Baggage-RPO used on the San Joaquin Daylight painted in the orange/red colors. If anyone's interested I can forward a scan.
Rob Sarberenyi
RPO's and Daylights
The Shasta, San Joaquin and Sunbeam trains carried a working RPO. The San Joaquin Daylight first carried a Bag-Mail car with a 30' mail apartment. That was later replaced with a car with a 60' mail apartment. Both cars were rebuilt heavyweights. It is safe to say that the Shasta's #5000-5002 were the only RPO's built new for a "Daylight" service
The Sunbeam was the 2nd full train to use the 1937 Pullman built 77' and 64' Daylight cars with the headend and rear cars being the only cars different than the ones built for the Coast Daylight. It wasn't the Sunbeam Daylight (some call it the Texas Daylight, but if you're a Texan that's a slander). It certainly wasn't CALLED a Daylight. Compare Coast, San Joaquin, and Shasta trains.

Interior Paint
Interior color for Harriman style baggage cars & RPOs
In the early 1950s, the interior wall color on the 60' & 70' harriman style baggage & RPO's were most likely Sea Foam Green. Light Gray is also possible.
Jeff Cauthen
The USPO Railway Mail Service stipulated the interior paint colors for all RPOs inside the circa 1940s-1960s period, was a warm cream tone for the walls of the mail storage part of the car and a cool light green for the working mail "apartment"; white ceiling in both spaces. This standard was applied, according to Federal sources, to all US railroads. On checking the interior of the then-raw SP "shorty Harriman" RPO (ex-San Bruno Branch caboose) No.6008, the same interior colors were there in several good layers.

Jeff Cauthen
1949
The 1949 baggage-dorm and baggage-postal cars had interior colors specified per P-S builder's specs. Per those P-S builder's specs, they had their:
walls painted Post Office Green synthetic gloss interior enamel, Sherwin-Williams #0-42-G-1.
ceilings were Synthetic enamel gloss white #CH-9145.
interior lettering was C.S. 22 SP Black #7.
floors were C.S. 22 Maroon #4, but not fish racks.
Jeff Cauthen
Modeling Interior Paint
If I were doing a Harriman baggage or RPO in the pre-war era, I'd follow the recommendation to use No. 9 and No. 9A postal car brown on the walls (and I'd probably leave the floor varnished wood based on the Smithsonian photo and SP caboose practice, although Jeff hasn't mentioned roof or floor paint specification for the earlier cars).
For my post-war transition era, Harriman baggage and RPOs, I'll follow the 1949 P-S specification.
My doors will be closed, the baggage cars unlit, and there isn't much in the way of windows to peek in through anyway on an HO car. I won't be detailing the interior of these cars, so I just want "effect," so getting the paint right or close will be as much as I'll do.

40-BP Baggage PostalClass
40-BP-15 Baggage Postal Cars
SP #6009
These are 40’ RPO/Baggage cars.
ex-T&NO 251, renumbered SP 6009 6/25/1943, to baggage-express,
class 40-B; retired 12/1955, to caboose SP 475 12/11/1957; to R&LHS; at CSRM.
This car was built in 1911 as Houston & Texas Central (later T&NO) 251 (or 250). It was one of 5 class 40-P-1 40 foot full RPO cars built in that year for the Texas Lines of SP. Others were H&TC 250 (or 251), ML&T 191-192, and LW 193.
SP #4239-4241
Three similar cars were built for the Pacific Lines in 1909 as SP 4239-4241. These three were later transferred to SP de M.
SP #6008-6009
H&TC/T&NO 250-251 were transferred to the Pacific Lines in 1944, renumbered as 6008-6009. H&TC 250-251 were converted in June 1925. It is unclear which Texas Lines car received which Pacific Lines number, although it seems likely that they were renumbered in sequence. The cars were used frequently on the San Francisco Peninsula. The five Texas Lines cars were converted to baggage - 15 foot RPO cars in the 1920s. The Texas Lines were consolidated under the T&NO name in 1931, with cars retaining their numbers. Most were converted to baggage-express service, with the mail compartment removed.
SP 6008 became (MofW?) caboose 2132 in 1956, and was retired in Merced in 1964. SP 6009 became caboose 475 in 1956 and was used as a transfer caboose on the San Bruno branch. It was retired in 1972 and acquired by the Pacific Coast chapter, R&LHS. In 1979 it was purchased by the California State Railroad Museum. It was originally planned to restore it as a baggage-RPO for the museum, but the GN RPO was acquired and was nearly complete, so that car went into the museum.

69-BP-30-1 Baggage-Postal Head-End Cars
SP #6115-6117 SP Common Std. Harriman Mail Car
SP 6115-6117 were baggage-express cars, ex-O&C 5033-5035 after the postal equipment was removed from the postal apartment.
The SP Class 69-BP-30-1 cars had smaller windows in the postal apartment than did the later cars.
There are similarities between the Harriman "Southern Pacific" '69 BP- cars and the "Union Pacific" Harriman '69 BP- cars. Their is a book out that covers this subject rather thoroughly; Southern Pacific Passenger Cars Volume 3: Head End Equipment.
The first eight cars of this design were built in Lot 3843 to C.S. 232. Three went to SP (O&C) and 5 went to UP (O-WRR&N and OSL). They were essentially the same except for minor differences.

70-BP-15 Baggage Postal Class
70-BP-15s Baggage Postal Cars
The 70-BP-15 series was the most numerous of any of the heavyweight RPO cars on the S.P. system. The 70-BP-15 cars (classes 70-BP-15-1 thru 7) totaled 54 cars. Almost half were 70-BP-15-3s.
The most common RPO series had such a small RPO section: only 15 feet. one would think the RPO sections of these cars would have become obsolete by WWII because they would seem to be designed for servicing low-population routes where passenger service would be cut back first. Maybe the RPO interiors were removed from these cars to increase their baggage/express capacity and the extra windows permanently covered, as well as how long they may have served as manned RPOs.
The RMS was very cheap in its payment to the railroads for RMS space. For instance, even if a car in use had a 30' RPO apartment, if the RMS required a 15' space, that is all for which it would pay. The problem for the railroads was that it they could not continually redesign/remodel cars to fit the then-current RMS specifications. As a result, it seems that cars operated on RMS routes might have been disproportionately used with respect to the revenue derived therefrom. An economist could more completely address this issue.
An RPO is a "manned" car (even if it is within a portion of the entire car, the remainder of which might be handled by a baggage messenger).
The other options include "storage mail" When cars were no longer considered to be under RMS contract, the RMS appurtenances were removed and the cars reverted to baggage or storage mail service.

70-BP-15-3 Baggage PostalCars

The -3s had the same exterior appearance (2 doors, 5 windows on each side) as the 70-BP-30-1s built in the same year (1923).
The 70-BP-15-3 class (25 cars) were delivered with 15-ft. postal apartments, but were so arranged that they could be easily converted to 30-ft. postal apartment cars. Thirteen were indeed rearranged with 30-ft. postal apartments. Many other changes were made to these cars over the years. Thus, the 15- 3s had a "surplus" of windows because of its shorter (15 vs. 30 foot) RPO section.

#5217-5219
These are 80' heavyweight Baggage-RPOs. The five baggage-mail cars with 60-foot mail compartments were assigned to the San Joaquin Daylight and the Owl in the 50’s.
SP 5217 was rebuilt from baggage-horse SP 7247 and was assigned to the San Joaquin Daylight for most of the time until the mid-1960s. It was one of three similar cars (5217-19) and, as far as I know, never operated on the Shasta Daylight. When the Shasta Daylight had an operating RPO in the early 1950s it had a 30-foot mail apartment. 5217 has a 60-foot mail apartment.
Paint
SP #5217-5219 were NEVER painted TTG.
The article pg. 19 of Trainline No. 22, stated that all five cars were repainted to solid gray "after 1958." One of the Daylight-painted baggage-mail cars on the San Joaquin Daylight actually kept its Daylight colors up to at least 1962.

SPH&TS Volume 3 on head-end cars has photos of these cars.

Lettering & Numbering
The lettering reads:
1) United States Mail
2) Railway Post Office
SP 40 ft RPO Lettering
A 40 ft. RPO and the lettering went as follows:
SOU -- the door -- THERN PACIFIC -- the door -- LINES
car numbers were at each end below the belt rail SP 4239
UNITED STATES MAIL RAILWAY POST OFFICE was centered below the three postal apartment windows
The 1911 version was actually a baggage express car, and photos show it converted and in it's final appearance. For a photo go to:
A copy of Sweetland's SP in Color Volume 1, the photos are great but the captions not so much, there is a photo of a baggage express #6008 on page 75. It differs from the photo on the website in that the "Baggage" lettering is on the opposite of the car between the short door and the car end. The 1909 version has two short doors that both extend up into the letterboard. This lettering was after 1917. As built, it had SOUTHERN PACIFIC (no LINES) only between the doors and the car numbers did not have SP initials.

The 80-BP-60 cars went into service in 1950. The regularly assigned mail cars back then were 70-BP-30 baggage mail cars with a semi-streamlined arch roof, although the relief mail car had a regular arch roof. The baggage-mail cars were used on San Joaquin Daylight and the Owl, and in later years on the Overland Route.
