INTRODUCTION

Railways being the cheapest mode of Railways being the cheapest mode of transportation are preferred over all the transportation are preferred over all the other means.other means.

Everyday we come across many railway Everyday we come across many railway accidents. accidents.

due to the carelessness in manual operations due to the carelessness in manual operations or lack of workers or unnamed railway or lack of workers or unnamed railway stationsstations

 Existing System :- Manual/Physical gate closing & opening. Manual switch based gate closing & opening. 

Limitations of exit ing system:- Chances of human error. Time consuming. A lot of human resource is required.

Present project is designed using Present project is designed using 8051microcontroller.8051microcontroller.
