7.5 Preparation of railroad bed
Preparation and marking of the railroad bed should be done for perfect sleeper
placement. Preparation has to be done ahead of the sleeper layer and preferable by
other personnel. By the two following markings on the railroad bed, with spray colour,
high efficiency can be achieved in laying.
•
Aiming line along the railroad bed. This line has to be, preferable, done on left end
side of the sleeper. From machine operators view.
•
Line, on and perpendicular to aiming line. These lines show the position of the eight
sleepers on each lay.
The distance between each line is 4 x sleeper pitch.
Example: 4 x 600 = 2 400 mm (94.5 in)
WARNING!
Do not allow anyone near the working area during work because of the risk
of personal injury or death. Safety regulations for the carrier, regarding personnel in
operating area, are also valid for this attachment.
