Model Railroad H Beams and Girders

[nselegzi]

Hi, I'm interested in designing some parts for a model railroad kit that would let people make model elevated trains modeled after those remaining in New York City Most model train kits use resin parts, but I don't see that offered here, I'm assuming ABS or polystyrene would work. Do you have any recommendations?

Since I am going to want a lot of the same parts, I'm assuming that injection molding makes the most sense, but I just want to make sure before I start designing the parts.

I don't know what such parts are made of and recommend that you study our materials section at Materials and the IM materials table at Material Selection. Yes, Injection Molding seems the right way to go.
Please let me know if I can assist further.
