Rock Island Stock Car 75050

After review of the resin kits in the to build cabinet I chose Rocket Express Models Chicago, Rock Island & Pacific (RI) stock car, kit RI-6.1.  The stock car received number 75050 based on decals.  Rock Island stock car 75050 would be the first Rock Island stock car in service on my Minneapolis & Northland Railroad Company Railroad.

The prototype stock cars built in 1950 by the Ryan Car Company, series 75000 to 75249 were the last new stock cars built new for the Rock Island.  The stock cars were Howe truss design with wood sides and ends and a door one each end.   The cars had a Murphy mullion roof with wood running boards.  A color photo of 75010 can be viewed in the Rock Island Color Guide to Freight and Passenger Equipment ( Morning Sun Books Inc., 1996).

As with all resin kits the first step in the build is to remove flash.   A stock car takes a good deal of time to accomplish this task due to removal of the flash between boards on sides.  I follow the recommended procedure for this task by sanding the back of the sides and doors on a piece of 100 grit sandpaper lying on a flat work surface thinning the parts until the flash begins to disappear.  At this point I will use a scalpel to remove the remaining flash between each board.  After finishing with the scalpel I go back with a sanding stick with a point shaped like that on a sharpened pencil to sand between each board.   It is the removal of flash between boards that makes a stock car a unique build.

With the flash was removed, I began the build of this flat kit with the assembly of the “ basic box” consisting of sides and ends.  Normally I would install corner reinforcements and add a baffle; however, I did not do this on stock car for you can see into the car between the boards.  Next the roof was installed to complete the exterior car body; however, it required the tip of the ends be sanded to the shape of the rabbit in the roof to get a proper fit. A resin fascia piece is glued over the end of the installed roof.

Basic box with roof and fascia installed.

I fitted the underbody which required removal of material beyond coupler pockets on both ends to accomplish.  I installed cross bearers, cover plates and bolster plates.

Cross bearers, cover plates and bolster plates installed.

I drilled and tapped the coupler pocket pads and bolster center plates for 2-56 screws.  Kadee #262 narrow whisker gearboxes with Kadee #148 couplers were installed with Fastenal 2-56 x 3/16” screws.   Tahoe Model Works, TMW 106, Buckeye ARA 50 ton trucks included in the kit were installed with Fastenal 2-56 x 1/4” screws.  Car was weighted to 3.8 ounces with eight 1/4 ounce tire weights.

Couplers and trucks installed.

At this point in the build I did not follow the kit instructions to mount a brass bar that needed to be cut in half and a half glued  on each side of the interior carbody in a location determined using math calculations to create a underbody mounting support.  Instead, the under body was inserted into the car body with the coupler pockets extending over the ends to support it to determine the proper depth.  A pencil was used to draw a line in the interior of the car body above the floor via the door opening .   The underbody was removed and a Evergreen #8208, 2” x 8” styrene strip cut to the inside length of the car body, was glued above the line to act as a underbody support when installed.  The underbody was now installed.

Car body with underbody installed ready for detailing.

With underbody installed, detailing of the car body begins.  I drilled the holes with a #79 drill for end ladders consisting cast on stiles and drop grab irons for rungs, and all side and end grab irons.  I installed all grab irons on sides and ends and the grab irons for ladder rungs on the ends.

All grab irons installed.

On the “B” end the resin brake shaft mount (in photo on fascia) and resin brake shaft step were installed.  A Precision Scale #31796, retainer valve (not in kit) followed by a retainer line and brackets, Tichy Train Group (Tichy) #1100, .008” phosphor bronze wire (PBW) were installed.  Resin cast door handles were carved off and handles bent from Tichy #1101, .010” diameter PBW were installed.   

Brake shaft brackets, retainer valve and line installed.

On the sides I did not use the kit ladders you have to build with resin stiles and grab irons.  Kadee ladders, #2102, which matched the spacing of the end ladder were cut down to six rung ladders and installed.  In addition, I installed the upper resin and lower wire door guides using photos and instructions.

Side ladders and door guides installed.

On to the under body.  I installed the Tichy brake components provided in the kit.  I used a Sunshine Models brake cylinder bracket from the parts box to mount the brake cylinder and a plastic sill step cut from some plastic car for the air reservoir bracket near the crossbearer.  Brake lever hangers provided in kit were installed next.  Brake levers I made from Evergreen #8108, 1” x 8” and #8106, 1” x 6” strip styrene were installed.  The slack adjuster for the floating lever was made with a piece of styrene angle from the bits box with holes drilled in it with a #80 drill bit.

Brake components installed.

I continued on the underbody installing the following details:
- piping from air reservoir to control valve, Tichy #1101, .010” diameter phosphor bronze wire (PBW)
- pipe from brake cylinder to control valve, Tichy #1106, .0125” diameter PBW
- brake rods, Tichy #1106, .0125” diameter PBW
- chain attached to brake rod and brake cylinder lever was provided in kit
- clevises for brake rods made with MEK Goop
 - train line, .018" flora wire (not in kit)
 - dirt collector, Tichy, set #3013

Underbody details added.

Onto the roof details.   The longitudinal laser cut running board was installed with Formula 560 canopy glue and weight added at the end of a modeling session to allow it to dry overnight.  The next day the kit provided photo etched end brackets were installed on the ends.  Prior to install,  mounting brackets for latitudinal running boards cut from .005” x .040” photo etched brass were glued to running boards with Formula 560 canopy glue with extensions on rear for gluing to the longitudinal running board and on front for forming round roof mount section on the front.  I would have used the .010” x .030” brass flat bar in the kit for this purpose; however, I could not find it at the time.  Once the glue was dry the latitudinal running board brackets were bent to shape on the ends and installed. Roof wire grab irons provided in the kit were installed with Yarmouth Model Works photo etched eye bolts without shoulder (not in kit) for corner legs.

Running boards installed.

Sill steps were now installed.  A-Line #29000, style A, sill steps were installed rather then the kit provide plastic sill steps.  The mounting holes were drilled with a #76 drill in the sill.  The sill mounting brackets were cut from .005” x .040” metal foil in which rivets were made with RB Productions RB-T009 Rivet-R riveting tool.

Sill steps installed.

Back to the “B” end.  Uncoupling lever brackets consisting of a resin back plate and eye bolt were installed.  The resin back plates were glued to the sill.  After the glue was set, a #80 drill was used to drill a hole in the back plate and an eye bolt provided in kit was installed to complete the uncoupling lever bracket.  Uncoupling levers provided in the kit were installed.

Uncoupling lever bracket, uncoupling lever and
 note brake shaft bracket.

The brake shaft, Tichy #1102, .015” diameter PBW was installed.  Prior to install, a small resin gear form my parts box was installed onto brake shaft to sit above fascia mount as on prototype.  The kit provided Tichy brake wheel was installed.  A small disk was added to the center to match the prototype. A mounting bracket below the end door (see photo above for closer view) was made made with .005” metal foil.  The vertical brake shaft was not added until now due to its height which is about the same distance as that between the end drop grab iron ladders rungs.

"B" ends details completed.

Back to sides to install the doors.  I do not install doors until the end of the build as the area under  doors prior to install provides an area to hold the car during various stages of the build.

Doors installed.

Car is ready to prep for paint.  I washed the car body and underbody with a cotton makeup swab dipped in 91% alcohol.   Now the paint.

 The underbody was sprayed Vallejo Model Air 71.055, Black Grey RLM 66.   The car body was sprayed mineral red mixed with Vallejo Model Color: Black Red 70.859, 75% and Flat Yellow 70.953, 25%, thinned 50% with a custom mix of distilled water, Vallejo air brush thinner #71.161 and Vallejo Airbrush Flow Improver 71.562.  If  a lighter mineral red is mix desired use 50% black red and 50% flat yellow.

Immediately, after spraying back to the workbench to begin running board weathering.   I used a cotton makeup swab dipped in 91% isopropyl alcohol and removed some of the paint from the laser cut running boards to expose the wood.  This was the first time I had thought to use this weathering method with a laser cut running boards.  I liked the result and will add it to my weathering methods.

Paint removed from running boards.

After paint dried overnight, I added the hand painted control valve protective shield  cut from resin flash.  If the shield had been added earlier the control valve would have been difficult to paint.  Now, the car body was sprayed Vallejo Gloss Medium #70.470, for decal base.

Shield to protect control valve added.

I lettered the stock car with decals provided in the kit. The decals were applied with MicroScale Micro Set and Micro Sol.  The reporting marks and number due to printed size had to be located on board above bottom board as in prototype photo.  Some Rock Island stock car photos have the reporting marks and number in this location.  Due to reporting marks and number location the data decals had to be adjusted accordingly.   When decals were dry, the car body was sprayed with Vallejo Matt Varnish 70.580, to protect dry transfers and decals during handling and for weathering.

Rock Island stock car 75050 built in 1930  would be showing a weathered look running in spring of 1955.  Therefore, I applied weathering to the car using the following Pan Pastels:  Paynes Grey Extra Dark 840.1 on the roof, Netural Grey Extra Dark 820.2 on the sides, Paynes Grey Tint 840.7 in spots over the Netural Grey Extra Dark to provide a lighter aging and Red Iron Oxide Extra Dark 380.1 for fading the lettering.  I used the photo in Rock Island Color Guide to Freight and Passenger Equipment book as a guide for my weathering.

After painting and lettering was completed the car could enter service on the Minneapolis & Northland Railroad Company after a car card was made.  Rock Island stock car 75050 will be delivering cattle to Swift located in Northfield, Minnesota on the Minneapolis & Northland Railroad Company.

MIlwaukee Road Steel Gondola 93100

After building state of the art plastic and resin kits in recent years, I felt it was time to build an “oldie” resulting in Ullrich, kit 931-1301, coming out of the to build inventory.  The kit is a white metal kit with manufacturer painted sides and lettered for Milwaukee Road Gondola 93100.  The gondola in this kit with changes builds into a very good stand in for the prototype since it does not have  dreadnaught ends like the prototype.

Ulrich painted and lettered sides.
(Click or tap on this or any photo to enlarge.)

The prototype was one of Milwaukee Road (MILW), class GS, 200 all steel cars assigned to series 93007 to 93206.  These cars had fixed sides and ends with sixteen (16) individually operated  drop doors hinged at the center sill.  In the early 1950’s the MILW converted some of these gondolas into low cost chip cars by adding  wood extensions.  A photo of a Milwaukee Road gondola in this series, MILW 93093, can be found in Milwaukee Road Color Guide to Freight and Passenger Equipment, Volume 2 (Morning Sun Books, Inc., 2000). A reproduction  by the National Model Railroad Association of  the January 1953 Official Railway Equipment Register shows 165 in general service.

No underframe to build as it is a white metal casting with ends attached.  As with any kit the flash has to be removed.  A scalpel with old blade, file and Dremel tools with diamond cutting disk and grinding bit were used to complete the task.  I did wear eye protection while performing any cutting or grinding task.  Once the flash was removed, I installed the insulated bushings into the metal underframe and tapped them for 2-56 screws.

Kit instructions show insulated bushings,
underframe with ends and floor plate.

 Next, the drop doors were installed in a closed position on the floor pan with gel CA rather than the underframe as instructions show.  The doors designed to actually operate can be installed as working doors if you design a method to keep them closed when car is in service.  When all doors were installed the floor pan was glued to the underframe.

Next, I installed Kadee #262 Narrow whisker snap-together grearboxes into the cast coupler pockets on the underframe after removal of mounting post for kit provided metal coupler cover.    An easy install since the Kadee coupler box fit without further alteration to the metal coupler box.  Accurail  ARA cast steel with spring plank trucks with InterMountain 33” metal wheels were installed with Fastenal 2-56 x 1/4” screws.  

Coupler boxes and trucks installed.

Next I installed the sides which requires just a little bending to accomplish.  With the sides in place, the car was placed on a digital scale to find the car’s weight.  The digital scale read 4.6 ounces making the car on the heavy side.

Sides installed.

Before starting to add the detail items to the car I wanted the white metal primed. Therefore, I hand brushed all non-painted white metal areas with Vallejo Surface Primer, 70.601.  If I had wanted to spray the primer I would have done it prior to adding the sides.

The primer drys quickly so I was able to hand brush the primed areas except for the interior in a couple of hours.  I was able to match manufacture’s paint with Vallejo Model Color Mahogany Brown 70.846, two drops in a water bottle cap to which was added a very tiny drop of Vallejo Model Color Calvary Brown 70.982.  The tiny drop was that formed on the tip of a round toothpick inserted into one drop of the Calvary Brown placed into another water bottle cap.  I mix paint in small batches using drops as  I can create the same paint mix and very little paint is required to cover small areas or added details.

White metal primed areas painted.

On the sides the sill steps were not correct per prototype photo so I cut off the rungs and straightened the remaining sides.  I used Detail Associates #2524, .010” x .030” brass flat bar stock to make new rungs.  Cast metal grab irons were ground off with grinding bit in Dremel tool.  On the “B” end side Grandt Line #5124, Freight Car Ladders were installed.   The same ladder is available as Tichy Train Group (Tichy) #3065 with 14” rung spacing.  On the “A” end side Red Caboose plastic grab irons from the parts box were glued in place with gel CA.

Metal cast grab irons ground off and new sill steps installed.

Ladders installed.

I moved on to the  “B” end work.  A shorten Grandt Line #5124 Freight Car ladder was mounted first.  In order to add the power brakes on this car I had to cut off the cast in mount for a vertical brake shaft and the slot in the brake step was cut deeper for the chain to pass through. A Tichy, set #3013, brake housing with chain installed was installed.  I followed this by mounting the brake shaft step, Tichy #3013.  To allow it to mount flush with the edge of the end the right angle bracket in Tichy set  #3013 was glued to the car sill and the brake shaft step on top of it. A brake rod, Tichy #1102, .015” diameter phosphor bronze wire (PBW) was cut to fit between chain and bottom of the brake shaft step.  The last detail item, the brake wheel from Tichy set #3013.  I did not grind off all the end grab irons and replace them during this build.  Maybe a future upgrade?  Onto underbody work....

"B" end details added.  Cast grabs not yet removed and
replaced with plastic grab irons.

Note the brace behind the brake shaft step.

On the underbody I completed the following tasks:

- metal brake component mounting pads were cut off with diamond cut off wheel in Dremel
- air reservoir and brake cylinder, InterMountain spare parts, installed
- control valve and brackets, Tichy #3013, installed
- brake lever hangers, Red Caboose plastic grab irons from spare parts
- brake levers cut from, Evergreen strip styrene #8108 1” x 8” and # #8106 1” x 6” 
- floating lever adjuster, styrene angle
- piping control valve to air reservoir, Tichy #1101 .010” diameter PBW
- brake rods, Tichy #1106, .0125” diameter PBW
- brake rod clevises, MEK Goop (plastic melted in MEK)
- drop door support bars, Evergreen #261, .060” channel
 - plastic kit sprue used to make plugs to fill holes in cast underframe

Underbody details installed.

MILW gondola 93100 was ready for paint.   I hand painted all primed areas and added details parts using Vallejo Mahagony Brown with a tiny drop of Model Color Calvary Brown stirred in.  On the gondola ends Vallejo Gloss Medium #70.470, was applied to provide a gloss base for decals.

Underbody painted.

End reporting marks and number decals, provided in the kit were coated with MicroScale Liquid Decal Film due to age to prevent any breakup problem while being soaked off backing paper.  Once dry, decals were soaked off in distilled water and applied to the car body ends 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.  When decals were dry, the car body was sprayed with Vallejo Matt Varnish 70.580 to protect decals and paint during handling and for weathering.

 and plastic grab irons installed.

MILW gondola 93100 painted and lightly weathered.

Light weathering was applied using eye shadow makeup and Pan Pastels  Payne’s Grey Extra Dark 840.1, applied with makeup brush, cotton swabs and micro applicators.  MILW gondola 93100 was ready for the display case rather than putting MILW 93100 in service on my Minneapolis & Northland Railroad Company.

The yellow lettering on this gondola would have been applied in the early 1960’s which is beyond my railroad timeframe of late spring 1955.  Red Caboose produced this MILW gondola with number 93187 with correct dreadnaught ends and white lettering that is in service on my Minneapolis & Northland Railroad Company.

After building the Ulrich white metal MILW gondola 93100, I know I will not be building many more white metal kits due to the cutting and grinding time involved.   I will go back to plastic and resin kits with a greater appreciation of how easy the material in these kits is to work with to build a finer model.
