Champaran HumSafar Express : इन अजनबी सी राहों में, जो तू मेरा हमसफ़र हो जाये, बीत जाए पल भर में ये वक़्त, और हसीन सफ़र हो जाये. - Piyush Singh

3 Strong Possibilities

1) Extend 22421/2 to Barmer(BME)/Jaisalmer (JSM) instead of mandore

2) Extend Brahmaputra mail to barmer/JSM instead

3) make RJSK daily up to JSM/BME via Bikaner as no one will say anything about cancellation of weekly train of jodhpur(JU).

4) extend 22481/2 upto BME/JSM (cancel the RSA with BDTS-JU suryanagari express, suryanagri exp can be made RSA with mandore exp )

Anyway, JU will not lose anything as then one full daily train will be both towards BME/JSM & both these stations will likely not be able to take full quota in both trains & half quota will be there for JU.
