Yes correct. While others are weekly, what I meant is the time slot used is same for all trains. They somehow were able to manage as the time of arrival of those trains were post peak hrs. This is my view. Also it is to be noted that in the last many years 13352 is the highest reveneu generating train for SR at least amongst the top 3 ( Kerala exp & Mangala exp being the other two). You are right that Tata-ERS has ended up getting a raw deal with by passing Chennai, VSKP, CBE and a very DD time of dep from Tata even though it is a SER train. Its arrival at destination ERS is at an very odd inconvenient time. Hope they somehow try and change that if possible
