I hav travelled a couple of times and my each experience regarding jerks:-
1. Adi - Ndls - Rajdhani -1ac - almost no jerks
2. Ju- jp - 18244 BGKT - BSP exp - sl- too many jerks
3. Hte - Pune - 22845 sf -3ac- too many jerks
4....
more... Cst- Rou - 12869 sf- Sl - felt jerks only while departing
5. Rou - hte - 22845 sf - Sl - too many jerks.
Now after travelling in LHB, I feel ICF more comfortable but I think safety is more important than Comfort of short period.
