i dont knw from where u have seen the pax for shatabdi from karnal
local newspaper and even spotted several times that trains come and just halt and go at karnal and sonipat both
sonipat halt is removing in upcoming month may be in july
as karnal it is a political stoppage due to CM and MP
karnal...
more... no where stands in terms of railway thats why most of the trains didnt halt even not so many express and sf
while panipat an industrial town
regarding kalka shatabdi
yes from delhi to panipat not so much pax on daily basis on weekend so many bookings done
and on daily basis from panipat to kalka/cdg/umb so many bookings done
demand is in evening so much high, as in morning several trains like Himalayan queen, shan e punjab, pathankot express etc trains takes so much pax
so many business class people due to industrial area of haryana, equidistant from delhi and chandigarh train wants shatabdi train in evening slot
