Welcome to the 29th edition of the Proto48 Modeler. It is the start of the summer season and time to escape the heat and head to the basement or shop to do some modeling.  A number of new kits being made available will give you something new to focus your energy on.  You could also work off you incomplete projects or unbuilt kit.

We are in a era of change brought on by companies dropping out and others being purchased.   The loss of Northwest Short Line appears close at hand.  San Juan Model Company has gathered up a couple key firms and moved them to a suburb of Denver.  Grandt Line, San Juan Car Company, San Juan Decals and American Limited Models.  Change is hard to deal with because of the uncertainty it creates.  Over the years a lot of suppliers have disappeared yet the scale continues.    

New kits and new suppliers are emerging this year.  We have a good selection of plastic and urethane kits on the market.  There are a ton of discontinued kits are out there at train shows and eBay.  There is a lot to build if you are feeling the urge.

New kits that are on the market currently:

Glacier Park Models Southern Pacific G-50-22 Gondola kit

Modern Era O Scale Gunderson 50' boxcar kit

Twin Star Cars’s new 53'6" flat carkit

Smoky Mountain Model Works AAR 70-ton flat car kit

Learn About Proto48

The Proto48 Modeler website is the place to find out information on 1/4" scale products and modeling techniques. You find current information on products and also for modeling techniques.   There are lots of pictures to check out. 

Proto48 is a subset of the larger O scale model railroad hobby. We build to exact scale standards for wheels and track gauge.

This e-magazine is focused on standard gauge modeling. Proto48 defines a gauge and wheel profile for locomotives, cars and track but it also expresses a concept of finescale modeling. Our models start out with the correct gauge of 4' 8 1/2" and scale AAR wheel profile and continue throughout the model to create an accurately scaled replica of the prototype.

Quarter-inch scale offers railroad modelers a huge potential in terms of size and mass. It is big enough to permit the craftsman to accurately portray things like underbody details, doors, roof walks and ladders. Proto48 standard gauge modelers tend to strive for higher levels of detail and accuracy like their narrow gauge brethren.

Proto48 is more than just model making it covers the building of layouts and the inclusion of prototypical operations. There are an amazing number of P48 layouts being construction around the country. They range in size from switching layouts to large railroads with many hundred feet of scale track. Check out the layout page on the Protocraft website to see a few of the layouts built or being built.


If you don't have room or time to build a layout, you may be lucky enough to find some fellow modelers in your area that you can share your interest.

You will find a number of new items listed. We can always use more material that will permit more issues to be published each year. As always, we are indebted to the modelers who take the time to send material to share with others. We hope that this spirit of sharing will continue allowing us to bring fresh material to the web so that it can be enjoyed by everyone.

Blogs are becoming a popular way to communicate with modelers of similar interests.   There have been a few blogs that have been going for some time and a new one or two.

George Losse continues with his website providing information about modeling the Reading in Proto48 and modeling meets.  He travels to a lot of the O scale shows on the East Coast and provides a narrative and photos of his visits. George will often get pictures of new products that are being shown. You will find a number of helpful ideas and techniques as he builds his Reading Company Shamokin Division railroad in P48.

Archer Transfers
PO Box 1277
Youngsville, NC 27596

Archer Transfers has solved one of the more difficult problems in modeling steel equipment.   They have invented a process to deposit a 3D resin on Microscale clear decal film.   They have expanded their line to include various rivet patterns and sizes, safety tread material, fasteners, panel lines and even louvers.   The product is very useful not only to solve difficult fabrication projects but it also saves a lot of time.   The decal is cut out and applied to the model like a normal Microscale product.   We recommend you do not use any decal solvent until it is has evaporated all of the water and you are happy with the position.   Then you can apply the solvent around the edges.   The film will disappear.   The decals must be covered with paint since it will chip off otherwise.

Smoky Mountain Model Works
35 Springwood Drive
Asheville, NC 28805
(828) 777-5619

SMMW has decided to give O scale a try again after about a ten year hiatus. Jim King is busy developing a 3D design for the AAR 70-ton flatcar. This car is different from the earlier 50-ton War Emergency design. The car was built for at six roads. The appearance is different in that part of the center sill and bolster tops are visible as part of the car decking. The stake pockets are of different design and they were delivered with 5'8" wheelbase 70-ton trucks.

Protocraft will be importing the 70-ton truck in three different spring configurations. They will also be doing at least six custom decal sets for this project. Both are not included with the flat car kit.

Jim's 3D design is printed using a SLA process which produces very smooth masters. The printed parts are molded and cast in very high-quality urethane using a pressure technique.

Go to

SMMW is about to release their second kit for a low side Southern Railroad gondola. It is being produced using the same 3D printed/ urethane cast process.  An S scale version of the car can be viewed on their website

If you have any questions, please contact Jim by phone.

Wild Swan Publications, LTD
1-3 Hagbourne Road
Didcot, Oxon  OX11 8DP

Wild Swan Publications has a wide range of books on English railroading.  Recently, the published two soft-bound books on Modeling Trees by Gordon Gravett.  The first part covers Broadleaf trees and second on Conifers.   The basic technique involves build an armature (trunk) of florist wire and covering it with a mixture of plaster and PVA glue.  The author has illustrated the book with many model and actual tree photos along with a number of very useful techniques.  

A third volume is about to be released.  The latest book by Gordon Gravett deals with modeling grasslands and landscape detailing.  I have not seen the book yet.

I first learned of the books through Trevor Marshall and his Port Rowan blog.  It is S scale but he is an entertaining author and shows many techniques for layout building that work in any scale.   Visit Trevor's blog and enjoy.  http://themodelrailwayshow.com/cn1950s/

You will also enjoy seeing Gordon Gravett's work on a 1:50 scale French meter gauge railway.  Everything is scratchbuilt.  Stunning work to say the least.
