Kitbashing an Atlas Hopper

Finished Model

Introduction

An Atlas HO Covered Hopper model is used to create a Blue Sun Mining 700 Series
hopper car. I didn't chop the length as it is only a few scale feet too long for my layout
standards. For simplicity, the hopper bays are covered with styrene to look like one
huge bay--all that is necessary is a shape.

  • (1) Atlas HO Trainman®ACF®3560 Covered Hopper
  • (2) side extensions: styrene strip .030 X .188 X 5 5/8"

Disassembly

Removing the Roof Turn the car over and remove the hatches on the two outer hoppers. Then remove the Phillips screws inside. Lif off the top.

Construction

Removing Roof Mounting Posts On the inside, cut off the roof mounting posts flush with the bottom.
Stock Car End Modified Car End
Cut the ends even with the slope sheet. This can be done on the car but works better if removed first.
Scraping The Top Edge Scrap the top edge with a knife in order to remove thin lip the top sat on.
Gluing The Ends In Place Tube Styrene cement is used to glue the ends in place.
End Detail Of Side Board Side Board In Place
The side extensions are glued to the top of each side. This makes the sides as tall as the ends.
End Walkway Made From Roofwalk End Walkway Made From Styrene Strip
A piece of boxcar roof walk (get from a junk boxcar body, or you may find something available as a detail piece) or a piece of the side extension styrene strip can be used for end walkways.
Prepping The Bottom Turn the car over and remove any details that will hinder the styrene pieces from laying on the hopper bottoms and sides.
Bottom Sheet Glued In A piece of styrene is cut to cover the flat areas of the hoppers.
Hopper Sides Two more pieces of styrene are cut and glued to the hopper sides. Once the car is painted and on the track, all that will be seen is the shape and possibly any surface texture.
Construction Is Finished Construction is finished.

Painting and Decals

Removing The Lettering This is a can of Floquil paint thinner. I don't recommend trying what I am about to tell you on any other model as this thinner melts plastic very quickly. I only used it here as the lettering on the Atlas car was thick. I put some of it on the cotton swabs and rubbed the fine lettering which immediately came off. I kept moving up the lettering sizes, using the thinner sparingly. Everything came off except for the main roadname, which I left.
Light Primer The body was lightly sprayed with gloss white spray paint, not primer. The goal is to somewhat equalize all the colors, not to paint the car white--notice that the bay is darker than the car body, and the factory lettering still shows through. Paint is on light and appears to be gray instead of white.
Paint Color I chose Krylon Satin Pebble for the car body color and sprayed several light coats.

Read my article "Make Your Own Decals"to find out how I made these and applied them to the car body.

Decals are applied and the whole car sprayed with flat clear (Testors Dullcote). This was my first attempt at making my own decals. The decal film was thick and didn't set well on the ridge. The poor lighting in this photo makes the car look gray instead of Pebble.

Final Details

Car After Trucks And Couplers Added Trucks and wheel faces painted Testors Flat blue. Kadee whisker couplers added. Nothing like model photography to show all the faults of a model!
Car After Light Weathering Added Here is the completed car on the track. Light weathering was done by dry brushing the Light Sea Gray over the car. The bay sides received a bit of the Earth Brown. The Pebble color is weaker than I had hoped. The car is already at the proper weight. You may want to adjust the trip pins on the couplers to make sure they are at the correct height.
