Respected Sir,

In 2010 I had cleared RRB exams( had applied to the post prior joining the current govt job) and attended all the procedures such as document verification,medical exams conducted by railway personnel branch.I informed them that I am central Govt employee(Under probation).I need some time to join my duties and the same day I had applied for extension of joining time.But to my concern neither I have received any appointment orders nor approval for extension of joining time.As I am willing to join railways after obtaining proper clearance from previous employer..Kindly advice me the information what further course of action should I take?Whether extension of joining time can be given in railways or not? if yes kindly tell me where i will get the concrete notes? The railway authorities are verbally saying that they cannot give the extension so what can I do now?kindly help me?
