Since Raptisagar, Ahilyanagari and Korba TVC's terminal has changed to Kochuveli, it would not be a problem to shift the terminal of Rajyarani express to Trivandrum Central.
Rajyarani can be made to depart from TVC at 20.40 to make way for the huge incoming traffic. If PM at TVC is the issue, then the rake can be shunted to Kochuveli for PM, like Kerala expess.
If passenger associations could raise this issue along with the clarification, it should succeed. As intrastate short distance trains should not be terminated at satellite stations.
