Compact and UPS-friendly 1x1 loaders. Works with train cargo wagons, circuits, filters, and modded belts from Bob's, Krastorio, FactorioExtended Plus, Space Exploration, and Ultimate Belts.
They act partially like belts, in that they can have items still on them, but they don't block anything, i can't mine them, and I can't use the deconstruction planner either.
And as shown in the image, I have placed a passive provider chest under one.
