SWR don't want to stable train more than 3hrs so all these trains getting one side ont perfect slot for 07153 is perfect slot 07154 become clone to sheshadri and similar situation for 08543/4 but some how different because it is starting 3:50 pm if it starts 13:30 pm it can reach 9:30/50 am but SWR will send return at 10 to 11 am again so all these trains have one side perfect TT but rather than nothing something is better
