True. SR had "proposed" to LHBfy TVC CSTM and TVC VRL express. But I dont know when the proposal is going to materialise. TVC Mail and MAQ SF are the only ones with LHB that too both are MAS Divn trains. PGT-POY has got very few trains after conversion. SR needs to start giving elocos to all trains from MAQ. I think TVC NZM was using CBC. No idea if it still runs with CBC. The prestigeous Kerala Express itself ran with old coaches. Even ERS SBC SF needs new coaches.
