This is the second post in my series of MDC Food-Service Kitbashes, specifically this time on the 1937 Cafe-Lounge conversions of the 72-D-3s. Last time I started with the 77-D-2 Dining Cars (Part 1), and the odd-ball car of that class which was converted to a unique Cafe-Lounge pilot conversion in August 1936 of SP 10910, about six months before these cars were converted in 1937.

I pretty well finished my first model back around 2016, but I didn't quite finish the car. A few small details like the A/C roof vents, stirrup steps, and adjusting the interior to fit properly with the car's internal weight.

I've noticed now, in 2026, that I should have also corrected the size of the windows in the dining and lounge sections too, so I'll be working on that later here as well. However, let's start back at the beginning.
Prototype Cafe-Lounge & Dining Cars
I know it's painted in the wrong color for passenger service, but the SPMW 7021D is my model of a 72-D-2 class Diner, which was a very similar design to the 72-D-3s which we're looking at today, before they went through the Cafe-Lounge conversion in 1937. This photo nicely shows the original window arrangement of the six evenly spaced windows in the main dining section. The roof-top swamp cooler I believe was a non-A/C modification which was applied at some point, possibly after MW conversion of the 7021D.

I should add here that Chicago & Alton (608 & 609) and Oregon Short Line (369) both had 72-D-3s as well, plus UP had some cars similar as well, although the 72-D-2 and -3 as-built only had 5 windows in the dining section when new.

| Excerpt from my Timeline of the SP's 72-D3 and 77-D-2 Cafe-Lounge conversions from the 1930s to 1960 era. |
The five cars of 10911-10915, were rebuilt from the old 72ft non-A/C diners from 72-D-3 class. The rebuild included changing the 3 sets of windows away from the kitchen by pushing them about 3ft towards the end of the car. They retained the 2'5" window columns in the dining section's 3 windows, but had 2'0" columns between the lounge section windows, which I won't be replicating on my models because I just noticed that in 2026, not 2012 or whenever we started these kitbashes... oops.
Also of note, the dining car section of the SPHTS Vol.4 shows that SP 10012, 10013, 10015 (72-D-2s) were painted in TTG3, and 10012 suggests this was done in Sept 1948. All four cars including the 10014 received Waukesha 1 Enginator A/C in 9-11 1937 when they were converted to Cafe-Lounge service.
The rest of the SP's 72-D-3s (except SP 100011), SP 10000-10002 and 10004-10005 were never upgraded with A/C and were all retired in 1948 & 1949, except for 10002 which was leased to the CCC in 1937 and then to R&LHS in 1938, before being stripped in 1938, and finally retired in 1940.

SP 10913, Construction 2014-2015 Era

By this time I've already roughed out the body kitbashing enough to actually have the trucks under the car body and the roof roughed out as well.

These cars retained their bulkheads at the end of the frame with the vestibules, thus retained their 72-D classification, not increasing the structural frame length of the floor. the doors on the SE and NW corners were enclosed, leaving only vestibule doors with steps at the SW and NE corners of the car. I'm not sure why the door was kept at the lounge-end of the car.

The Kitchen windows were cut open all the way to the bottom of the letterboard. This is to allow blanking styrene plugs to be placed in the lower window opening to replicate the kitchen windows of the time, which interestingly probably was the first appliance of this window style on the SP Diners, which didn't seem to get this style until about 1940.
SP 10913, Completed 2017 Version
 |
| Left side of the as-completed kitbashed model. |
I pushed forward back in the day, fitting the car with underbody equipment parts and some interior tables and lounge chairs from Palace Car Works. The Kitchen was a stolen Rivarossi Diner interior kitchen. The wind-vane smoke jacks came from Kit-Bits from BCWs, which I believe are out of production now sadly. I believe most of the underbody equipment is PSC plastic parts.
 |

I used the MDC step wells and my standard Walthers HW 6-wheel passenger trucks, which should allow future LED lighting in the car. The car was finished with Star Brand SP Dark Olive Green paint and ThinFilm-160 lettering for post-1946 SP lettering arrangement. The window shades are aluminum painted paper shades.
SP 10014, 72-D-3 Diner, Post-WWII Era (March 2026 Work)
This whole time I've had a second Cafe-Lounge body, which I've not finished past basic primer. This one I believe was actually roughed out by my friend John Ruehle. Once I put the SP 10913 into service, the requirement for a second one was relaxed some as another car was used in La Mesa Club's second West Coast consist, leaving the SP 10913 to work as the Cafe-Lounge on one consist alone.
 |
| Left side of SP 10915 |
So this second body was planned to be Cafe-Lounge SP 10915 to be in the second West Coast consist, but then fell by the wayside as it wasn't really as needed, so it has sat for 10-12 years now.
 |
| Right side of SP 10915 |
This body had more issues with damage to the rivet rows of the MDC body panels, and a couple of the joints were a bit rougher than the SP 10913's body, thus why I put the 10913 into service first. I did give the body a shot of SP Dark Olive Green, but that really showed that I needed to do more body work before committing to putting decals and more mechanical work into it.
 |

However, now that we have have Archer Rivet Decals, and their Pullman Rivet Pattern decal sets, I'm going to start doing more body work to complete this body.

The roof also seems to have a bit of a bow in it, which I'll have to work out what to do with as I get the car farther along. I'm considering reusing some of the Athearn-MDC era magnetic roof retaining pieces to draw down the middle of the roof over the dining section.

Not that much to more to say about the other side looking into the interior.
Converting from SP 10915 to SP 10014
At this point, I looked again at the SP Lounge Timeline Graphic for the 72-D-3 Cafe-Lounge rebuilt cars.
|
| Excerpt from my Timeline of the SP's 72-D3 and 77-D-2 Cafe-Lounge conversions from the 1930s to 1960 era. |
The interesting thing about history is... nothing ever works out the way it was planned to. The majority of these Cafe-Lounges were pulled back into the shops in May 1942 and the lounge chairs were pulled out and tables were placed back into the 'lounge section', converting them back into 'dining cars' again. The cars had their numbers and lettering changes on the exterior of the cars.
The SP 10011 was retired in 9/49 and converted to serve as SP 145 1/5/50 as a air-conditioning Instruction Car, with most of its windows covered over with sheet metal and painted DOG, then TTG in 1955, before being converted again to a conference car in 10/59 and painted in SSS of the era and finally being retired somewhere around 1970.
The SP 10014 seemed to be the longest lived of these ex-Cafe-Lounge turned Diners, the SP 10014's history is a little simpler. Being retired in 1/51 and transferred to SPMW service in 2/53 as SPMW 646, the car was transformed into the dorms and offices for the crew of the Rail Fissure Detector Car as their "Tender". The car was still painted in Dark Olive Green until circa 1954, then in TTG until about 1985 when it was repainted to the Solid Gray scheme. According to the Business Car book by SPH&TS, it was always operated with SPMW 4520 (ex-USAX Kitchen Car), turned supply and maintenance car which complemented the support of SPO-1001 and SPO 4901 detector cars, which were painted Daylight and have been made available in brass. As for the revenue version of the model, I've settled on the SP 10014 as the Diner to squeeze most of another year out of the model compared to the SP 10011.
I should note that, given the SP did the same type of thing to the dining section of the San Joaquin Daylight's Triple-Unit Diners, swapping 2/3s of the dining tables out for lounge seat and small drink stands in low traffic times during 1949, which usually only took a few hours and a few men to swap the tables and chairs around during layovers at Oakland and Los Angeles. This makes me think that all of these Cafe-Lounge cars could have been temporally swapped back and forth from Cafe-Lounge to full Dining configurations depending on traffic needs and train assignments.
This reason alone makes them an interesting car to select to model to increase the operational options of how to employ the car. I am currently looking at having some non-77-D-3/4 options for extra passenger trains, charter groups, etc and MAIN (Troop) train movements for Korean War. The SP seemed to get rid of their non-A/C 72-D-3s by 1949, too bad as they would have found use with the MAIN trains within a year of their retirements.
So now that this car body has a proposed new life, I've decided to start seriously looking into what it will take to finish this body into Diner SP 10014, instead of the sister car SP 10915, which remained in Cafe-Lounge service.
I'm starting the 2026 rebuild to raise the top of the windows to match the size that the prototype car's windows were replaced with in 1937, which I missed in my first kitbashing of this model 10 years ago. So it's time to take it in hand again.
Maybe... just maybe, I should have split this post into two posts... but as these cars are so closely connected I think it's better to just talk about them in context as they each tell a different part of the same story.
I will look into posting a Part 2 of this post soon when the Archer Rivet Decal order arrive for the SP 10014 or when I do more work of significance on the SP 10913's window modification. I expect that the mechanical (underframe, bolsters, etc) won't be done on the SP 10014 until the body work is sorted out, but I know many of you that read these blog posts are interested in the mechanical work on these scratch built and heavily kitbashed cars for your own projects, so I'll try to take extra 'how-to' pictures when I'm working on that part of the car again.

What Makes a Diner or a Lounge?
I should note that, given the SP did the same type of thing to the dining section of the San Joaquin Daylight's Triple-Unit Diners, swapping 2/3s of the dining tables out for lounge seat and small drink stands in low traffic times during 1949, which usually only took a few hours and a few men to swap the tables and chairs around during layovers at Oakland and Los Angeles.

Time for some Body Work
So now that this car body has a proposed new life, I've decided to start seriously looking into what it will take to finish this body into Diner SP 10014, instead of the sister car SP 10915, which remained in Cafe-Lounge service.
 |
| Left side with Liquid Surface Primer applied over splice joints. |
I also used some of the Tamyia Liquid Surface Primer (LSP) as a more precise sand-able filling compound than something like Squadron Putty, which shows here as vertical columns of darker gray.
 | |
|
At this point I've decided it won't really be worth trying to use "S-scale" Archer Rivets to replace the original MDC rivets on both sides of the car where I'm going to need to sand the LSP filler.
 |
| Right Side of the body after flat-sanding down the splice joints and rivets. |
This results in my sanding the whole car side down smooth and eliminating basically all of the original rivets.
 | |
|
The resulting depth of the Dark Olive and underlying primer being exposed, and the LSP on top. Oddly enough, having the car in this strangely colored arrangement, it actually makes me think of some of the modern condition of surviving passenger cars during various stages of preservation and repainting. Not sure I would want to keep the model in this condition though, as I have a mission for it. But it does make one consider what some of these cars looked like during their yearly shopping if heavy repair and repaint work needed to be done.
SP 10913, March 2026 Rebuilding
I'm starting the 2026 rebuild to raise the top of the windows to match the size that the prototype car's windows were replaced with in 1937, which I missed in my first kitbashing of this model 10 years ago. So it's time to take it in hand again.
 |
| Left side of SP 10913, starting rebuild |
The first step here is the marking of the work that I need to do. I took the interior out from the dining and lounge sections so I don't damage them. Next I popped the windows out, however the wall sections in the non-kitchen end sandwich the clear styrene windows in place, so I can't remove the glazing at that end. I'm hoping that I can work around damaging the plastic windows too much during the rebuilding.
 |
| Right Side SP 10913, starting rebuild |
I was able to get the glazing out on both sides of the dining windows and the aisle section. I'll be covering most of this car's 2026 Rebuild in future parts of this post. Let's look at the other car that's not as far along.
In Closing
Maybe... just maybe, I should have split this post into two posts... but as these cars are so closely connected I think it's better to just talk about them in context as they each tell a different part of the same story.
