So basically to summarise here is what TVC division says.
• ERS-RMM express cannot be started- Reason terminal constraints
• ERS-Salem Intercity express- Will examine viability of service
• Demand for more memu trains in morning-ot possible due to Lack of terminal facilities
• Making...
more... Amrita & Rajyarani independent trains-Not possible due to lack of terminal facilities
So in a nutshell highly unreasonable to expect something in near future in Kerala
