Railway Reservation System Activity Diagram | UML

Railway Reservation System Activity Diagram | UML

Railway Reservation System Activity Diagram – is a UML Diagram built to give the proponents the right ideas on how to develop the said software with explanation. When designing this system activity diagram, you must know the flow of activities done in doing Railway Reservation. Why is that? it is because this will help you, your readers and users about how should the software behave once it is in use. It’s activity diagram is illustrated with the use of symbols like actors, swimlanes and arrows to understand the Railway Reservation System core.

The users of this Railway Reservation System would be the Online Railway Passengers or Customers. They were the one’s who must be determined first before doing the Railway Reservation System Activity Diagram. They serve as the actors who will use the system and then you will design a series of activities or reservations processes that happens on the system.

What is a Railway Reservation System Activity Diagram?

Railway Reservation System Activity Diagram – to have a clear explanation about it, let me tell you its purpose and role. The Railway Reservation System must have an activity diagram so that the programmers would have a basis on how should the software approach its users. It is because, the activity diagram guides the programmer in creating the software and its must-have behavior. So if you want a friendly and effective or easy-to-use software, then you must also complete the activity diagram.

Through the activity diagram, you’ll be able to illustrate the flow of activities and know what should be the interactions between the system and its users. Your readers and users will also be guided about how would they use the system by looking into its activity diagram. So its best for you to explain your thoughts on Railway Reservation system through activity diagram.

Activity Diagram Symbols:

Now before we create the Activity diagram of Railway Reservation System, you must know first the symbols used to make it. And here are the symbols used in Activity Diagram.

You must be familiar with these symbols in order for you to distinguish what should you put in the illustration to avoid misunderstandings. This is also to educate you about the activity diagram used so you and the users would understand the system’s behavior.

In addition to that, being familiar with these activity diagram symbols will help you show the detailed parts and interactions that should happen when you develop the System. Then this thought enables you to have right ideas on how you would develop the system that you want.

Additional Knowledge

The activity diagram works perfectly with the other UML Diagrams which were available also on our site. They are the Railway Reservation System Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram and many more. These diagrams served as the blueprint designs to foresee the needed functions of a working Railway Reservation System.

Activity Diagram of Railway Reservation System

Here’s the activity diagram explanation of Railway Reservation System that you may use for your Final year Project. Note that you may change the ideas given in this activity diagram to meet the scope of the Railway Reservation system project that you desired. The given ideas here are sorted based on the system users to give you more detailed examples.

  1. Designed Activity Diagram of Railway Reservation

    Activity Diagram for Railway Reservation System
    This activity diagram for Railway Reservation System gives the explanation of the general flow of activities when doing a Railway ticket reservation online. So as you can see, the customer will invoke the system then the system caters the customer’s request. Then the customer will request to avail a reservation for the railway, so the system will then check of there’s still a reservation available. Then the customer will process the reservation and the railway crew or admin will confirm the reservation.

    Now to create this kind of diagram, you have to determine the processes involve, the users and finalize the behavior of your proposed system.

You should be informed that these diagrams can be modified to achieve your desired system behavior. You can also create your unique system function to justify all of your clients needs. And if you want, you can copy all the ideas presented here and add them to your project design.


It is essential for you to know the explanation diagrams used to design and develop the Railway Reservation System. That is because you cannot perfectly create a fully-functional system without it. But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

By completing the Activity Diagrams per module or per processes, you will easily achieve your desired system.


Now, what have you learned through our discussion? Have you determine the Diagrams that you must create? What project do you have in mind?

And if you have ideas or concerns with our discussion, do not hesitate to leave us your suggestions and questions. Your thoughts are highly appreciated. Thank you so much and have a good day!
