My portable Little Current layout needs a way for everything to be stored securely. I have way more rolling stock than I would ever use in one session of switching and that’s a good thing. I there are lots of chances to add variety but it all has to go somewhere safe when not in use.
For this layout I used ULINE X-14222 19X12X3″ White Tab Locking Literature Mailers. I cut 1 1/4″ strips of cardboard to taped inside spaced on 2″ centers. I tape the top of the cardboard so that stirrups and other details don’t snag as easily. The box will hold 30 40′ box cars with a little bit of extra space for loads or other details. Passenger cars fit one per row with a little room to spare. These went together quickly once I had all the sizing worked out.
These ULINE Literature Mailers fit perfectly into IKEA Kallax shelf units. I stack them 3 at a time, there is room for a fourth if I need but I like the extra space.
Stopping in the middle of construction to do this was hard, especially when I had an OK place to keep them. I have to say the time was worth it and my collection is way more safe. I can quickly put the layout together and finding cars to set up for switching is now a breeze. Best of all I have lots of space, so when that perfect car comes out that I “must” have, I definitely have room.
