Before covid it used to leave HWH with 19 coaches out of which one SLR detached at GTL making it 18+4 slip = 22 coach train. Now it comes with only 18 coaches from HWH as now longer 2A class present in this train. So entire 18 coaches from HWH go to VSG in addition to the 4 slip coaches. I think SER is simply too lazy to change the name boards or in future they will augment with a 2AC so they might have to detach the SLR at GTL again.
