URTX Refrigerator 4682 leased to MStL

Union Refrigerator Transit Lines (URTX) wood refrigerator car, URTX 4682, assigned to series 4675-4699, was leased to The Minneapolis & St. Louis Railway.  A photo of URTX 4697 in the 1937 paint scheme, page 106 and a photo of UTRX 4975 with the 1930’s paint scheme as on URTX 4682 is on page 107 in Refrigerator Color Guide by Gene Green (Morning Sun Books Inc., 2005).  I also received a photo of URTX 4975 (not the one in Refrigerator Color Guide)  from Tim O’Connor for this build.  I used these photos as a guide for my build and upgrade of plastic kit #4682 purchased from 5th Avenue Car Shops  ( no longer in business) who had Accurail  produce the car using their 4800 series wood refrigerator.  The car was painted and lettered by Accurail except for car numbers which have to be applied by the modeler using decals provided in the kit.

As you can see when viewing photo of URTX 4975, the prototype had wood tongue in groove sides and ends.  It also had a wood roof and wood running board.  A vertical non-powered hand braked. The hatches had a distinctive hatch handle combined with an integrated metal frame that merged with the hinges. Under the wood was a steel-framed structure and a straight channel center sill.  And, a very visible feature are the ice bunker drain pipes.  The cars were built with KC brakes which were replaced with AB brakes in 1940-1950 time frame.  Trucks were the planked, cast side frame ARA design.  These cars were built built by General American in 1930-1931 for Union Refrigerator Transit Lines who leased them to the M&StL and other Mid-Western roads as the Milwaukee Road and Soo Line.

I began the assembly and upgrade of this car on the underbody by installing the kit fish belly center sill followed by couplers and trucks.  The kit provides plastic pins to install the trucks and molded on pins on coupler pocket covers to attach them to coupler pockets.  I used neither.  I cut the molded on pins from the back of the coupler pocket covers and used the remaining spot to drill and tap a 2-56 hole for mounting with screws.  Next the truck bolster center plates were drilled and tapped for 2-56 screws.  Kadee #148 “whisker” couplers were installed in the coupler pockets and Fastenal, 2-56 x 3/16” screws were used to attach the covers.  InterMountain 33 inch metal wheels were inserted into kit provided Accurail trucks that after removing the brake shoes were installed with Fastenal, 2-56 x 1/4” round head screws.  A Kadee #208, .015 fiber washer had to be installed on center plate bolster to obtain proper coupler height.

Now the kit brake components, after drilling them with a #79 drill for piping  to be added later, were installed.  The brake cylinder molded on mount was cut at an 45 degree angle to make for a prototype looking mounting bracket.  And,  for the air reservoir mounts, a piece of strip styrene from bits box was glued from side sill to center sill.  Brake levers were cut from Evergreen strip styrene.  The brake cylinder lever was cut from Evergreen #8108, 1 x 8 and the floating lever from #8106, 1 x 6.  The kit provided car weigh, attached with Permatex adhesive sealant clear RTV Silicone, weighted the car to 4 ounces.  With these tasks complete, I glued the underbody to the car body. 

Brake components installed.

On the B end of the car the brake shaft step as molded is not an open step.  Therefore, I used a drill and broach to open the brake shaft step.  

Brake shaft step with molded material removed.

After opening the brake shaft step I carved off all the molded on grab irons.   Next I carved off all ladder rungs leaving only the ladder stiles.  If you are interested in what tools  I use for removing the molded on grab irons please go to “labels”  in the side bar and click on “carving off parts.”

Now the upgrade of the roof was done including running board milling, making distinctive hatch hardware, and grab iron install.  The running board was milled thinner, from .040” to .025”, using a Dennis Storzek technique described in his article, “5 boxcar improvements”, in April 1982, Railroad Model Craftsman, on page 84.  Once milling was done, the milled area was scraped with a single edge razor blade to get it smooth.  You could sand it rather than using the scraping method to get it smooth.   When the back was finished it was installed.  With the running board installed, new running board extension support brackets on the car ends were made from Evergreen #8102, 1 x 2” strip styrene and MEK Goop was used to make fasteners.

The upgrade of ice hatch hardware was next.  After ice hatches and hatch levers, Plano #12079, provided in the kit, were installed, the remainder of the distinctive hatch design hardware was made.  To match the prototype hinges, a URTX General American Car Company refrigerator car diagram was used to make the hatch hardware.  URTX General American Car Company refrigerator 35-Ton car diagram for the C. M. St. St. P. & P (MILW) appears in the 1931 Car Builders’ Cyclopedia (Simmons-Boardman Publishing Company, 1931).  The diagram showing the leased MILW refrigerator is the same used to build refrigerator car URTX 4682 leased to the M&STL.

For the hatch hinges, to make the metal hatch hardware,  a scale 22 inch grab iron and brackets were bent for each hatch cover using Tichy Train Group (Tichy) #1101, .010 diameter PBW and installed.  To finish the roof, roof grab irons bent from Tichy #1101, .010 diameter PBW with Yarmouth Model Works eye bolt without shoulder for corner leg were installed in new #79 drilled holes.

With the roof finished, I continued the car body upgrade by drilling new holes using a #79 drill to receive grab irons on sides and ends and ladder rungs.  The molded on rung fasteners on the molded on ladder stiles were used as a guide to drill holes for wire ladder rungs.  Ladder side rails were shortened to better match prototype photo.  Next I bent straight grab irons  from Tichy, #1101, .010” diameter PBW ( see “grab iron bending” under labels on side bar on this blog) and installed them.   After install of straight grab irons was complete, I bent the ladder rungs from Tichy #1101, .010 diameter PBW and installed them.

To finish the sides molded on sill steps were cut off.   New sill steps, A-Line #29000, were installed.

To complete the car body, B end upgrade work was done.  I began by cutting off the molded on brake step brackets.  New brake step support brackets, Tichy brackets from set #3013, were installed.  A Tichy retainer valve from AB set #3013 was installed followed  by installing a retainer line and brackets made with Tichy #1100, .008” diameter PBW.  A brake shaft, Tichy #1102, .015” diameter PBW was installed to replace the kit provided brake shaft with a .020 diameter.  On the brake shaft a Tichy brake wheel, AB set #3013, was installed to replace the thicker kit provided one.  A brake shaft bracket was made with scrap wire and installed.  Uncoupling levers bent from Tichy #1106, .0125” diameter PBW were installed with eye bolts I bent from  .010” diameter brass wire ( for bending ucoupling levers go to "labels" on side bar and click on "uncoupling levers").

B end details installed.

With car body details added, the remaining underbody details were done.  Piping from air reservoir to control valve, Tichy #1101, .010" diameter PBW and  pipe from back of brake cylinder to control valve, Tichy #1106, .0125” diameter PBW wire were installed. Next a train line using Tichy #1103, .020" diameter PBW was installed.  The train line holes were drilled in bolsters and cross ties with a drill made from .032 diameter hard (piano) wire.  A dirt collector, Tichy Set #3013, was now installed connecting its molded on pipe to the train line with a connecting tee made from MEK Goop.  Brake rods, Tichy #1106, .0125" diameter PBW, where glued to brake levers was covered with MEK Goop to simulate a clevis connection.   Chain installed between brake cylinder and brake rod is Tichy #8334, black 40 links per inch.  Ice bunker drains cut from Kadee bracket grab iron sprues were installed.

Upon finishing the underbody work URTX refrigerator leased to the M&STL was ready for paint and lettering.  The underbody was hand painted Vallejo Model Color #70.862, Black Grey.

To match the yellow-orange prototype paint match used by Accurail, the URTX refrigerator car body new wire grab irons and ladder rungs were hand painted Vallejo Model Color Light Orange, #70.911, on sides and Mahogany Brown , #70.846, on ends and roof.  When paint was dry, car body was airbrushed with Vallejo Gloss Varnish, #70.510 to provide a gloss surface for decals.

I used photo of URTX 4975 as a guide to apply kit provided number decals for sides and ends.  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.  Once dry, the decals were cut on board lines with a single edge razor blade and MicroScale Micro Sol applied again to get decal cuts to settle in board grooves.

After setting overnight to air dry, car body was airbrushed with Vallejo Gloss Varnish, 70.510,  to better hide edges of decals and protect decals during handling.  Again after air drying, the car body was airbrushed with Model Master Acryl Flat Clear, #4636, to protect decals and provide a flat finish for weathering when applied.

Decals, number only, applied.

One more step before putting URTX 4682 in service was to weather the car with Pan Pastels.  Pan Pastels Neutral Grey #820.5 was applied over entire car body with a medium size model paint brush.  Next Paynes Grey Extra Dark 840.1 was used lightly over car body and roof with a makeup brush.  Finally, Raw Umber Tint 780.8 was used to make light spots on areas among ladder rungs.   The Raw Umber Tint was applied with a micro applicator.  After each color application a makeup brush was used using vertical strokes over the entire car to soften and blend color.   A cotton swab was also used to blend colors.
