Dear Participants of ARC 2023,

We hope you had a pleasant and safe trip back home.

It was a great pleasure and honor to have you with us at ARC 2023, held from November 1 to 3, 2023, in Jeju, Korea. On behalf of the Korean Society for Railway and Organizing Committee, we would like to express my sincere gratitude for your active participation and involvement in the conference.

This ARC 2023 was an overwhelming success with a total of 122 presentations, attracting about 300 registered participants from around 20 countries and providing great intellectual and social interaction for the participants. We hope all participants had a meaningful time listening to the presentations and having fruitful discussions on scientific and technological issues with experts worldwide. We also hope the conference provided you with a good opportunity to build up ever-lasting friendships with many participants.

Without your support, the conference would not have been as successful as it was. We trust that you found your involvement in the conference both valuable and rewarding. The photographs taken during the conference are now available for download on the website at www.arc2023.kr, and you can enjoy and share the memories about ARC 2023 in Jeju, Korea.

Once again, we would like to convey our deepest appreciation for your contribution and wish you good health and happiness.

We hope to see you all again at the next ARC!

With best regards,
