With frequency increase, the 24 hr turnaround will no longer be there. It will mostly be PF turnaround. Train 18189 will arrive at ERS around 1:45am & return journey 18190 will start at 7:15am if you look at the new days of operations. Maybe around 5-6 hrs time available. If 18189 gets delayed, then 18190 will also have a delayed start.
