  • 718 Shape corrected Number/name corrected Appearance

    The isolating track was drawn as a 2 cm buffer stop with only one joint. It is a straight track of 88 mm with two joints.

  • 733 Shape corrected Type corrected Number/name corrected Appearance

    The isolating track was drawn as a 2 cm buffer stop with only one joint. It is a curved track R1 with 24° (like 702) with two joints.

  • 720 Appearance

    Sleeper layout redone: exactly one end sleeper per track end, at the joint (previously doubled).

  • 720 Shape corrected Type corrected Appearance

    The piece was listed as a crossing, but according to the manufacturer it is a double slip (30°, R1 curve 342.5 mm). It is now a double slip with both curved routes (radius 342.5 mm); the joints stay where they were.

  • 739L Appearance

    End sleeper added at the joint (joint marker).

  • 739R Appearance

    End sleeper added at the joint (joint marker).
