Not RCF itc ICF perambur. As per one of the article last time I read it was mentioned that once in 3 year these EMU trains should undergo complete overhaul which will take 15-20 days.
please wait...Translate to HindiBhai RCF nahi hai, ICF Perambur hai. Ek article mein pada tha ki EMU trains ko 3 saal mein ek baar completely overhaul karna chahiye jo 15-20 din leta hai.
