Both SHM LTT and SHM VSG should be LHBfied ASAP but the thing is SER is not getting necessary LHB coaches allotted from the production unit. And both in total require 8 rakes means around 176 coaches (excluding spare coaches) and so far since April SER has got only 15 third AC from RCF, one GS and EOG each from ICF.
These days I'm regularly tracking coach allotment to SER since I'm too much excited about SHM VSG LHB conversion.
