But Bikaner need a daily primary maintenance slot for a daily new train extension or to start a daily new train and only ranakpur exp can be extended upto hanumangarh because lgh dbrg, chetak exp, bkn dee sf, leelan exp and ju bti exp can't be extended further to any place for primary maintenance so only ranakpur is left for emptying the daily primary maintenance slot in Bikaner for new trains. And aravali express and sgnr bti exp can also be sended upto hanumangarh for primary maintenance.
