Indian Railways — train name and no not displayed

Address:

642126

On 24/04/2018 my wife took ticket for cbe-palani passenger train no 06709.
Usually this train will be at platform no:6. When she go to the 6th platform a train carrying a name board of shoranur. All the passengers confused for a while. Every time this train does not display name or no board. Passengers always get confused. No one in the station ready to change the board.
