5.2.6 Assembly of jointed rails
Jointed (multi-part) rails must be assembled according to the markings applied. The joints of each section are identified in a
consecutive alphabetical order as well as by the rail/pair number so that each rail section can be clearly assigned.
Each joint has a printed label on the top side of the rail. The printing provides aid for the initial assembly and can be removed
at any time using a suitable cleaning agent (e.g. ethyl alcohol). For jointed multi-part rails, the word “Paar” must also be
provided in addition to the rail number.
For paired multi-part rails, the butt joints should be staggered.
