Well, I guess I'm a little different than a lot of you 100% train nuts. 😂 I never cared for floor to ceiling train shelving, but have just used what's available in the basement man cave and train room to store my trains that aren't running on the layout. Being a small operator, this makes sense for me.
I spend more time in my basement, sound proofed "music studio" which is under lock and key, practicing my pedal steel than I spend operating the trains. But to escape the studio, I do break out occasionally to run trains during welcome breaks.
So, my train shelving is sparse, compared to most of yours. But they do the job.
