Even I don't have much idea about it honestly but have heard others saying SWR is only interested in freight revenue from VSG side. Otherwise, it is not a big deal to make it a headline about 2nd Pitline in construction they should have done it long back maybe they are purposely holding it back and also the work could have been done in lockdown too. KR electrified the whole strech in corona made full use of lockdowns as no to little movements of train. I don't know why SWR ignores VSG so much in terms of passenger traffic.
