"I could be wrong, but I think T stands for Transferred locomotive. I learned that if R comes after the road number, such as 11117R, it indicates that the unit has been rebuilt."
please wait...Translate to HindiT arthath transferred loco ho sakta hai, lekin main sure nahi hun. Ab mujhe pata hai ki agar sadak ki sankhya ke baad R likha ho, jaise ki 11117R, to yah punar nirman ek tha.
