To continue to reduce the plastic freight car inventory in my unbuilt kits cabinet, I pulled out 5th Ave Car Shops kit, CMO OB (outside braced or single sheathed) Boxcar 58864 for build and upgrade. The kit is an Accurail 4000 kit produced for 5th Ave Car Shops. I purchased the kit in 2003 from the CNW Historical Society at Trainfest in Milwaukee, WI. The kit includes a car body lettered for the Chicago, St. Paul, Minneapolis & Omaha (C ST P M & O) with reporting marks CMO, data and C&NW herald being a subsidiary; however, no number as that is applied using the decals provided in the kit. The decals have only the number 58864 for the sides and reporting marks and number for the ends.
After removing the car body from the box, I began the build and upgrade by immediately cutting off the molded on sill steps and in an attempt to rework the brake shaft step into a prototype shape I broke it.

Prior to starting the build and upgrade of Chicago, St. Paul, Minneapolis & Omaha (the Omaha Road) , CMO 58664, research had been done regarding the car and photos found for the build. The prototype car 58664 was in CMO (a C&NW subsidiary) assigned series 58000-58998 (even numbers) built in 1927 by the Standard Steel Car Company. CMO 58664 has the single sheathed features of the initial built cars including eight-panel sides with U-section bracing, Youngstown corrugated steel doors, grab iron ladders on the sides and typical ladder design on ends, Murphy 7/8 corrugated ends, Hutchins Dry-Lading roof, vertical staff hand brakes and underframe of United States Railroad Administration design. The cars rode on Andrews or Dalman two level trucks.

Earlier 1920s built cars had wood doors, and KC brakes upgraded to AB brakes as CMO 58664 in the late 1940s and early 1950s. CMO 58864 was built to the same 1925 design as CNW 47422 when new with part changes as the corrugated steel doors.

Additional photos and data regarding the CMO and C&NW cars can be found in Mainline Modeler, September and October, 2003. And, Steam Era Freight Cars Reference Manual, Volume One: Box & Automobile Cars, Speedwitch Media, 2006,2007).
Back to the build and upgrade of CMO 58664 using above photos. Work on the the underbody was next. The kit provided steel weight was attached to the inner side of the underbody with Permatex Clear Silicone Adhesive.

For the underframe of United States Railroad Administration with straight center sill design the kit fish belly was replaced with a new center sill made with Evergreen #136, .030 x .125 strip styrene. Much easier to do than trimming the kit fish belly center sill in kit to shape as shown in kit instruction sheet. Couplers, coupler covers with install pin cut off and trucks bolster center plate were drilled and tapped for 2-56 screws. Coupler pocket covers were installed on coupler pockets with Kadee #148 coupler inserted with Fastenal 2-56 x 3/16 inch screws. Basic kit brake components drilled and tapped for piping were installed. Mounts for the brake components: air reservoir the sill steps cut off the car, brake cylinder a resin cast Sunshine Models and AB valve an InterMountain inside door guide. Andrews trucks provided in kit with InterMountain 33 inch metal wheel sets inserted were installed with Fastenal with 2-56 x 1/4 inch screws.

After the trucks were installed the underframe was installed in the car body. The car body was ready for additional upgrade.

The running boards were milled and scraped to a thickness of .022 (see side bar for "Running Board Milling" for details) and installed. For the longitudinal running board install, Yarmouth Model Works (out of business) etched braces were used on the ends.

The carving off of the molded ladders and grab irons followed. In addition, a door slide plate was made from bits box styrene and installed over the side braces to the right of the door.

After carving off the side ladders, carving off the ladder rungs on the end ladders could wait for a time. Therefore, the B end upgrade was done with the following parts:
- Brake step, molded on
- Brake step brackets, Tichy Train Group (Tichy) AB set #3013
- Brake shaft step, Tichy AB set #3013
- Brake shaft, Tichy #1102, .015 diameter phosphor bronze wire (PBW)
- Retainer valve, resin from parts box
- Retainer line and brackets, Tichy #1100, .008 diameter PBW
- Placard boards, molded on
- Brake wheel, kit

Since I like to paint parts as I progress in the upgrade, the B end parts were brush painted Vallejo Model Air Brown RLM26, 71.105. An excellent match for the Accurail applied paint.

Once the B end was brush painted no sense putting the paint away, so the side areas where the ladders had been carved off were also brush painted

After the paint was dry, straight grab irons and straight ladder grab irons bent from Tichy .010 diameter PBW were installed on the sides. The bottom grab iron of the ladder was a drop type rather than straight type.

Now it was back to on the ends to carve off the ladder rungs and install straight type wire ones bent from Tichy .010 diameter PBW except for the grab iron at the bottom of the ladder which was a drop type.

To complete grab iron install work, the roof grab irons were as others bent from Tichy .010 diameter PBW and installed using a Yarmouth Model Works (out of business) etched eye bolt without shoulder for corner leg. In addition to finishing grab iron install, A- Line sill steps #29000 were installed. Prior to install the sill steps corners were heated with a Bic Lighter and squared with a Xuron 575 Micro-Bend pliers.

Once more it was back to the sides to add the the upper corner braces that Accurail had not molded on the car body. The corner braces were cut from .005 thick Evergreen sheet styrene and installed.

While waiting for the corner brace fasteners to thoroughly dry the underbody work was done. Upgrade parts were added as follows:
- Brake lever, made for Evergreen #8108, 1 x 8 strip styrene
- Floating lever, made from Evergreen #8106, 1 x 6 strip styrene
- Floating lever pin plate, parts box (part from a model car)
- Brake lever hangers, Tichy #3021 straight grab irons
- Piping from air reservoir to control valve, Tichy #1101, .010 diameter PBW
- Piping from brake cylinder to control valve, Tichy #1106, .0125 diameter PBW
- Train line, Tichy #1103, .020 diameter PBW
- Brake rods, Tichy #1106, .0125 PBW
- Brake rod clevises, shaped MEK Goop (plastic melted in MEK)
- Chain, Tichy #8334, black 34 links per inch
- Dirt collector, made with parts from bits box

| Underbody upgrade parts installed. |
Later, the underbody was brush painted with Vallejo Model Air Nato Black 71.251, a good match for the black Accurail underbody color.

When the corner side brace fasteners were dry, the corner braces were brush painted. And, the number areas receiving decal numbers provided in kit were brushed with Future Acrylic Floor Finish (manufacture renamed and repackaged since my purchase) to provide a gloss decal base. While the Future was drying, the kit provided decals, car numbers were cut out for application. After the Future was dry the decals were applied.

Decals were soaked off in distilled water and applied to the car body where MicroScale Micro Set had been applied with a brush. After the decal was applied in the Micro Set and positioned the edges had MicroScale Micro Sol applied. Any excess solution was sucked away with the torn edge of a paper towel.

All that remained to finish the car body was to install the uncoupling levers and brake shaft fascia bracket that had been forgotten when B end work was done. The uncoupling levers were bent from Tichy #1106, .0125 diameter PBW and installed with eye bolt brackets bent from Tichy #1101, .010 diameter PBW. The brake shaft fascia bracket was bent from Detail Associated brass flat bar stock #2524, .010 x .030.

Upon finishing the uncoupling levers and fascia brake shaft bracket install, they were brush painted with Vallejo Model Air Brown RLM26, 71.105. Now dry, upper corner braces installed on the sides with fasteners were also brush painted.

Once these last upgrade parts were dry, the car body was airbrushed with Vallejo Gloss Varnish 70.510 to better hide edges of decals and protect decals during handling. Again when dry, the car body was airbrushed with Model Master Acryl, #4636, flat to protect decals and provide a flat finish for weathering to be applied.
Chicago, St. Paul, Minneapolis & Omaha 58864 single sheathed box car was weathered with Pan Pastels. First, Paynes Grey Tint 840.7 was applied lightly with a small paint brush over entire car body to show aging. Next Paynes Grey Extra Dark 840.1 was applied with a large makeup brush on the entire car body and underbody also for aging. Red Iron Oxide Extra Dark 380.1 was applied lightly over the decals applied with a microbrush applicator to tone down their brightness. Car body applications were blended using a cotton swab and sponge. Burnt Sienna Shade 740.3 was applied to the springs with microbrush applicator tip.
