Gotcha ... Vaishali has 1.5 AC1 coaches whereas RNC Raj has only 1. It all depends upon the demand on a particular route. Ranchi has about 14 daily flights to New Delhi so a lot of business travelers prefer that over trains. On a side note RNC-HWH Kriya Yoga Express has A1, HA1 and HA2 Coaches.. What's your reaction to that? I am not trying to entice unnecessary reaction here, but just stating facts. Its a well established fact that there is a huge demand for Trains from Bihar compared to most other states due to huge migration issue (Mostly in the Unreserved category)
