advtrains_vactrain by Maverick2797 provides a vacuuming box wagon. It picks up items in a nearby radius as long as it is moving under a maximum speed and not stationary. It is a wagon with special utility in the same vein as the charger wagon from gpcf's Technic Train. Note that it has a lower speed limit than the box wagon, so it is not an equal replacement for higher speed goods, but it also has more inventory space (32 vs 24). It breaks even for steel if using basic materials without technic; it is net negative if using technic.
