answer of first question is YES and LR related information at nagda i dont know perhaps its not possible because trains coming from delhi or jaipur side via swm-kota-rma will take nagda route for reaching indore but if railway apporve ramganj mandi-ujjain rail line via soyat-agar then loco reversal at nagda will be vanished because currently it is road route from kota to indore i.e kota-jhalawar-jhalrapatan-raipur-soyat-susner-agar -ujjain-indore
