Hi Mahesh. Looks like now they don't have direct train from PTK to JDNX (honestly not sure why?) but I traveled in direct train from PTK to JDNX maybe 9 or 10 years ago it even had FC (no prior booking allowed but on board TTE allots seats by charging difference of fare). Infact i did DLI-PTK ONT and then took PTK - JDNX NG.
