I think when Trains are given LHB in SR , it's a sign of pessimism rather than optimism. Yes , even pandian got LHB , it had to encounter court cases. Now before any more trains get LHB in SR , the staff should be trained , especially in CBE MDU TEN yards. Cheran and Pandian which were maintained perfectly even with older ICF coaches are struggling now with new LHB coaches. And often , LHB coaches sent to south zones , especially SR and more specifically TN , i feel are dumped from north. Because we depended on RCF only to get LHB and they never gave it to us brand-new. Hope it becomes better in future with ICF also shifting to full-fledged LHB production.
