Manguluru to Kozhikode has 1 available spot in Sleeper, 17 in 3AC, and 2 in 2AC.

Looking at the trends, most of the occupied spots are from Kerala after Kasargod, as Manguluru is the final destination. The railway should consider building 2 lines for parking with water and general maintenance facilities at Kasargod or a nearby station and terminate trains like Malabar Express, Parsuram Express, and Vande Bharat in the morning heading to Trivandrum. They should also have a weekly train from YPR to Manguluru, like the 16324 Coimbatore Intercity slow train. The Manguluru terminal should have 2 parking lines, 1 pitline, and 2 platforms dedicated to trains heading to Karnataka in Manguluru central. Manguluru should also be given more reservation spots in Maveli and Manguluru-Chennai Mail and the stations after Kasargod should be in the RLWL category.

Considering that the majority of travelers are from Kannur and Kozhikode, there's no point in extending Vande Bharat to Manguluru in the future. Instead, we should pave the way for a Manguluru to Bengaluru Vande Bharat train with a morning departure.
