Those boarding/ alighting at Carmelaram should book only from/ to that station. Then the records will be generated properly.
Similar situation exists for BNC and SBC. People book from/ to SBC and board/ alight at BNC. So, no actual data is available for BNC. After some time, many trains may start skipping BNC citing low turnout. SWR is capable of trying out such ventures. They tried skipping BNC for KCVL-SBC express initially.
