A line sorter for sorting items of various shapes, sizes and weights, such as postal parcels or airport baggage, the line sorter comprising - an upper track section and a lower track section, where the upper section and the lower section are connected at end track sections, one end track section at each of two ends of the line sorter, - at least one position dedicated induction of items onto the line sorter, such as by an induction, - a plurality of discharges for sorting one or more items into their respective discharge, - a closed loop chain comprising sorting carts or slats coupled at couplings and for moving the carts or slats along the upper track section, the lower track section and the end track sections, wherein the couplings enable the carts or slats to pivot relative to each other about a horizontal or substantially horizontal pivot axis when in operation, - a linear synchronous motor propulsion system for moving said closed loop chain, the linear synchronous motor propulsion system comprising a stationary travelling field stator cooperating with a plurality of permanent magnets positioned on the carts or slats of the closed loop chain, wherein - a first continuous row of permanent magnets is formed by the magnets of a row of carts or slats along the upper track section and a second continuous row of permanent magnets is formed by the magnets of a row of carts or slats along the lower track section, and wherein the plurality of permanent magnets on the carts or slats follows or substantially follows a curve form at the end track sections, wherein - a gap between adjacent magnets in the first and second continuous rows of magnets is the same or substantially the same between each of the magnets, and each cart comprises a plurality of permanent magnets positioned after each other in the moving direction of the carts as a row of magnets, and wherein the gap between adjacent magnets in the first and second continuous rows of magnets is the same or substantially the same as a cart or slat gap between rigid ends of adjacent carts or slats. - an upper track section and a lower track section, where the upper section and the lower section are connected at end track sections, one end track section at each of two ends of the line sorter, - at least one position dedicated induction of items onto the line sorter, such as by an induction, - a plurality of discharges for sorting one or more items into their respective discharge, - a closed loop chain comprising sorting carts or slats coupled at couplings and for moving the carts or slats along the upper track section, the lower track section and the end track sections, wherein the couplings enable the carts or slats to pivot relative to each other about a horizontal or substantially horizontal pivot axis when in operation, - a linear synchronous motor propulsion system for moving said closed loop chain, the linear synchronous motor propulsion system comprising a stationary travelling field stator cooperating with a plurality of permanent magnets positioned on the carts or slats of the closed loop chain, wherein - a first continuous row of permanent magnets is formed by the magnets of a row of carts or slats along the upper track section and a second continuous row of permanent magnets is formed by the magnets of a row of carts or slats along the lower track section, and wherein the plurality of permanent magnets on the carts or slats follows or substantially follows a curve form at the end track sections, wherein - a gap between adjacent magnets in the first and second continuous rows of magnets is the same or substantially the same between each of the magnets, and each cart comprises a plurality of permanent magnets positioned after each other in the moving direction of the carts as a row of magnets, and wherein the gap between adjacent magnets in the first and second continuous rows of magnets is the same or substantially the same as a cart or slat gap between rigid ends of adjacent carts or slats.
