Q.1.
Describe the benefits of tamping in design mode. Also write down the pre
tamping and post temping operations for tamping of T/outs including the points
to be observed during tamping of turnouts for better retention of packing?
Ans: - BENEFITS OF
TAMPING IN DESIGN MODE: - Working of tamping
machine in smoothening mode reduces the track defects viz unevenness, cross
levels and alignment to only limited extent. Wherever, the tamping in design
mode corrects the track parameters up to a design value thereby eliminating the
track defects to a larger extent. Thus, good track geometry is achieved by
working of tamping machines in design mode. Comparatively longs sags and dips
in track are eliminated by designing the vertical profile of the track. Also
the long alignment defects are removed by using the sufficiently long chords
for designing the slews. However, obligatory points are to be kept in mind
while designing the vertical profile and slews for tamping in design mode.
