Indian Railways — late running of 12483 train

Dear sir/ madam

I am a regular passenger of the train kochuveli - amristsar sf express (Train no-12483).. But this train is always disappointing passengers including me because of its continuous late running every week.. This train is callled sf express, but it runs like super slow express... The main problem of super slow occurs between alwaye - thrisur route, thrisur_ shoranur route, where the train applies brakes for more than 20 minutes. This happens regularly every week. I dont know why this happens every time.. The main problem is it always give space to pass other local trains.

It is very sad to say that the punctuality of the train is very poor... Kindly make necessary arrangements to solve the problem and appoint a driver with good caliber

Thank you
Felix
