A low-pressure tubular system, for instance a vacuum tube train transportation system, comprising: a multitude of interconnected tube sections having a longitudinal axis; wherein each of the tube sections comprise a central part and two outer end parts; wherein the tubular system is configured to maintain a low-pressure environment within the connected tube sections; wherein the system further comprises a multitude of expansion joints connecting the tube sections; wherein each of the expansion joints comprises a sleeve made of a flexible sheet material and comprising a ring shaped endless central part and two ring shaped endless outer end parts; wherein each of the outer end parts of the expansion joints are arranged to extend coaxial with an adjacent tube section and surround and sealingly engage the outer end part of said adjacent tube section. wherein the flexible sheet material of at least the central part of the sleeves of the expansion joints each have at least two separate layers (601, 602), consisting of: a first layer of a flexible material that is air impermeable; a second layer of a flexible material that has a higher tensile strength in the axial direction of the tubular system than the first layer, and characterized in that the flexible sheet material of at least the central part of the sleeves of the expansion joints each further have a third layer of a flexible material that has a higher cut resistance and/or a higher puncture resistance against impact of sharp objects from the outside than the first layer and the second layer (603, wherein the third layer (603 surrounds the first layer. a multitude of interconnected tube sections having a longitudinal axis; wherein each of the tube sections comprise a central part and two outer end parts; wherein the tubular system is configured to maintain a low-pressure environment within the connected tube sections; wherein the system further comprises a multitude of expansion joints connecting the tube sections; wherein each of the expansion joints comprises a sleeve made of a flexible sheet material and comprising a ring shaped endless central part and two ring shaped endless outer end parts; wherein each of the outer end parts of the expansion joints are arranged to extend coaxial with an adjacent tube section and surround and sealingly engage the outer end part of said adjacent tube section. wherein the flexible sheet material of at least the central part of the sleeves of the expansion joints each have at least two separate layers (601, 602), consisting of: a first layer of a flexible material that is air impermeable; a second layer of a flexible material that has a higher tensile strength in the axial direction of the tubular system than the first layer, and characterized in that the flexible sheet material of at least the central part of the sleeves of the expansion joints each further have a third layer of a flexible material that has a higher cut resistance and/or a higher puncture resistance against impact of sharp objects from the outside than the first layer and the second layer (603, wherein the third layer (603 surrounds the first layer. a first layer of a flexible material that is air impermeable; a second layer of a flexible material that has a higher tensile strength in the axial direction of the tubular system than the first layer, and characterized in that the flexible sheet material of at least the central part of the sleeves of the expansion joints each further have a third layer of a flexible material that has a higher cut resistance and/or a higher puncture resistance against impact of sharp objects from the outside than the first layer and the second layer (603, wherein the third layer (603 surrounds the first layer.
