I am a regular traveller in the island express train. The local passengers (daily travellers) from Palakkad to Ernakulam are absolute nuisance. they board sleeper coaches and ask people to adjust and later start demanding and terrorising people. They board the coaches with full knowledge and they encourage there colleagues who board train in subsequent stations to board specific coach and they also inform seat no's. this is causing huge inconvienence to long commuters. TT's are mute spectators. Request concerned authorities to take strict action.
