Then we need to have all SF trains with same speed, express with same speed, Raj with same speed which is not at all tenchically achiveable in IR. You logic seems to be wrong with respect to IR which uses the same track for all types of trains. This can be done only if all SF trains have same stops and uses a dedicated track for SF trains alone.
Bikaner SF would be faster than many SF trains in that section. So, you want to reduce its speed to match other SF trains and also increase stops.
