Well I believe I'm misunderstood here. I posted my doubt to get it cleared. What I'm saying is that Name of the Engine is Azad and the Engine no us WP/P7200. This engine still exist and is in Rewari Steam Engine Centre. Secondly I agree initially Train name use be written on the steam engines ( Like Punjab Mail etc ) but in this case you can see its only Azad is written , no mention of word like Express . Also as much as my understanding goes, this engine use to belong to Northern railways. In fact you can read more about this engine in irctctourism.com/Trains/Fairyqueen/FQ001.html . I hope im not violating any copyright by pasting tis url :) :)
