I am going to build a simple inglenook layout using Peco Code 55 turnouts and sections. I am a beginner so I did some reading and determined that I will go with 4,3,3 car option. Here is what I have so far (designed using SCARM): SCARM has track measurement tool so it looks like I should be able to fit 40 ft cars. I am still debating if I should go with the red section that's going to be used for loco shed just to spruce things up. I know this is one of the simplest layouts but I would appreciate any feedback in case I am making a noob mistake somewhere.
