Activity Diagram for Railway Reservation System

The activity diagram for online railway reservation system is a UML activity diagram built to give the proponents the right ideas on how to develop the said software with an explanation.

When designing this system activity diagram, you must show the flow of activities that are done in making railway reservations.

Why is that? It is because this will help you, your readers, and users understand how the software should behave once it is in use. Its activity diagram shows the core of the Railway Reservation System with symbols like actors, swimlanes, and arrows.

The users of this railway reservation system would be the online railway passengers or customers. They were the ones who had to 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 reservation processes that happen on the system.

What is a Railway Reservation System Activity Diagram?

Allow me to explain its purpose and role in greater detail. The Railway Reservation System must have an activity diagram so that programmers can understand how the software should interact with its users.

It is because the activity diagram guides the programmer in creating the software and its must-have behavior. So if you want 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.

]The activity diagram will also help your readers and users understand how to use the system. So it is best for you to explain your thoughts on the railway reservation system through an activity diagram.

Activity Diagram Symbols:

Before we create the activity diagram for railway reservation system, you must first know the symbols used to make it. And here are the symbols used in the activity diagram.

You must be familiar with these symbols in order for you to distinguish what should go in the illustration to avoid misunderstandings. This is also to educate you about the activity diagram used so you and the users will 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 the right ideas on how to develop the system that you want.

Here’s the activity diagram explanation of the 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 desire. The given ideas here are sorted based on the system users to give you more detailed examples.

  1. Designed Activity Diagram of Railway Reservation

    This activity diagram for the Railway Reservation System gives an 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 to the customer’s request. Then the customer will request to avail a reservation for the railway, so the system will then check if 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 make this kind of diagram, you have to figure out the processes, the people who will use it, and the way it will work.

You should be informed that these diagrams can be modified to achieve your desired system behavior. You can also create your own unique system function to suit 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. This is due to the fact that, without it, it is impossible to create a fully functional system.

But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. You will also figure out what business processes are needed and link them to the UML diagrams.

By filling out the Activity Diagrams for each module or process, you will easily get to the system you want.
