Agree. In fact if i am not mistaken either S-8 and S-9 OR S-9 and S-10 are palakkad/coimbatore quota coaches. Ideally passengers with sleeper tickets are supposed to board these two coaches but invariably all the sleeper coaches are jampacked. After thrissur its relatively vacant. Even the new Ernakulam-Palakkad MEMU which moves ahead of this train probably till Thrissur is not able to reduce much load from this train .
