Short Notes on Design mode working of CSM

Design mode working of CSM:- 

For achieving good track geometric packing of the PRC track should be done by using CSM in design mode. However if the variation in level and alignment is very less than CSM temping may be done by using smoothing mode. In design mode temping rail levels of a particular section of track are recorded by using leveling instrument final levels along with gradients and vertical curves are to be decided carefully. The required lift and slew are finally recorded on every alternate sleeper. Temping should be carried out by entering the lift and slew at the front tower by adopting design mode of leveling and lining. By design mode temping desired track geometry can be achieved
