Custom AI Software Development can make improving the train ticket purchase process for 100M passengers smoother—even when you maintain a national company’s digital transformation for 11 years(!).
Improving the train ticket purchase process for 100M passengers doesn’t sound like a piece of cake. Same as maintaining the digital transformation of the national company for 11 years(!). How to do it smoothly?
Challenges with Digital Progress in Custom AI Software Development
Stermedia worked with the railway company from 2009 to 2019. It was a long business process during which we faced many challenges. Firstly, our task was to develop complicated system modules as part of a tailored AI software delivery for a national-scale operator. Until 2010, the work involved implementing the platform in cooperation with other companies. Solutions at technology change rapidly. So, every year there was a challenge of maintaining all the functionalities in accordance with the best technological standards. Each month of work involved adding new functionalities and implementing changes coming from the legal department. The last years of work involved the preparation of a complaint handling and recovery module.
Communication with Stermedia has always been at the highest level. Contracts and orders were delivered as intended. A team of 7 programmers performed this work, as well as the coordinator Adam Matusiak, were characterized by professionalism, diligence, and help in solving problems or suggesting the best solutions. The PKP Informatyka team involved in the project assessed the work of the entire team and Stermedia very highly in terms of content and organization.

Solution Tailored For The Client’s Needs: Tailored AI Software
The subsystem known as Mercury is responsible for this solution. This system consists of a mobile cash register (Terminal IT-3100), where the conductor manages ticket data, payment method and issues a print order. The ticket itself is printed by the Vega-Mobil fiscal printer, which communicates with the terminal using Bluetooth technology.
The Mercury subsystem is a practical example of custom AI solutions supporting secure mobile ticket sales in the field.
The terminal has a connection via RS 232 cable to the PINPAD 13070 device for card-based payment.
Finally, for security reasons, the mobile cash register also has a built-in camera that can be taken to a passenger who refuses to pay for the journey.
The solution enables business correspondence exchange by informing about events on the railway network: train difficulties, track repairs or accidents, etc. The terminal, thanks to built-in wireless GSM / GPRS communication, is able to update its database.
Results Of Custom AI Software Development
Platform implementation successfully completed and resulting in changes throughout the process. Creating a new version of a legacy system that is compatible with the latest functionalities and technology standards delivered through Custom AI Software Development and legacy modernization.
Integration of all parts of the system in an AI-driven custom system includes:
- ticket offices
- mobile sales terminals for conductors (Mercury)
- online booking platform
- system of billing, analysis, and statistics
The biggest challenge was the scale of the project and the prevention of code aging during 11 years of development.
