Modeling an SCL E7B
MARTY BERNARD: RICHMOND, VA
These two Seaboard Coast Line E7 B-units were photographed while in service on Amtrak’s Florida trains in the early 1970s.
styrene bonding strips were in place, the etched brass panels were added. I attached these with cyanoacrylate glue. I used little dots of cyanoacrylate to tack the panels in place and then went back over the seams with a bead of cyanoacrylate. With the porthole panel complete I moved upward to the air intakes. I used the same .020″×.040″ styrene to frame the inside of the intakes. This gives the metal screen a surface to be mounted to. There are structural mem- bers of the engine that show through the grilles, so these had to rebuilt from styrene. I used .040″×.060″ styrene to model these braces and eyeballed their locations based on photos. There are two openings on each side of the unit that have cooling grids in them. I modeled these using .010″ styrene sheet as a base and then cut squares of .030″×.188″ styrene for the grids. These panels were glued in place inside the openings with cyanoacry- late. Scale Scenics aluminum micro mesh was used for the screen, which was cut into rectangles to fit snugly in the openings and then glued in place with cyanoacrylate. A thin bead around the inside of the opening is enough to hold the screens in place. I removed all of the plastic lift rings on the roof and replaced them with De- tail Associates metal ones. These are so much more durable. Other details were added at this time as well. The di- aphragms, coupler cut levers, grab rails and m.u. hoses were all supplied by Broadway Limited. My etched parts in- cluded lifting rings which are attached to the top of the diaphragm housing. The B-end of the model (not the front end) has a set of drop style grab irons that run up to the roof as well as a cor- ner grab iron on the roof. Tichy makes the drop style grab irons, but the roof grab iron was .008″ phosphor bronze

unit. This looks like some kind of a sill or a step just above the m.u. hoses. I added the steps to the locomotive at
1. The areas of the shell that need to be removed have been marked with a pencil. Marking it all out first can help prevent mistakes when cutting. 2. Some areas of the shell have just a narrow rivet strip left. Much care must be taken when cutting and sanding these parts. The author spent quite a bit of time making sure that the cuts were all straight and filed cleanly.
