at BSR most of the trains are coming after 7 pm in the evening in the down direction. Trust me BSR traffic is not a problem for trains departing from BDTS or BCT in the given slot of 5-6 pm. As far as the traffic at BRC is concerned, I have seen couple of times when trains like 04714 - Bikaner SF departed 1 hr late from BVI at 5.30 pm and around 11- 11.30 pm at BRC. So BRC traffic is also not a problem. Believe me, there are ways and means to do it if there is a will. Otherwise what is the benefit of electrification and speed up upto 130 kmph.
