Suggestion to extend was because of patronage. Bikaner to SDAH end to end passengers nahi milenge, + diesel pull + Single track in most of the places + extremely congested route + loco change from Diesel to Electric at NDLS .
Agar extend karna hi tha to kuch viability dekhte. KLK/JAT/SVDK/ASR covers major cities with high traffic . Paisa to kamaa leti.. Yahan bilkul khali chalegi aur time table maintain nahi kar payegi.
