As per the annual plan SR had a list of trains for LHB conversion for the year and almost all of them have been converted. GT & PNBE ERS (weekly) were pending and now GT has also been done. So only PNBE ERS remains. What I have heard that the plan for accommodating Mangala is trying to be pushed. Not sure if it will happen as 6rakes are required. Its easy to get LHB for trains with lesser frequency.
