It has been a while since we have updated the game. We have been busy lately, so it has been delayed, but we are working hard and making steady progress. This time, the series SR4000 will be able to operate commercially. Originally, the series SR4000 could be seen passing each other on opposing trains, but now they can officially operate on the commercial operation schedule. As a generation, the series SR4500 is imagined to be a sister type of the SR4500 series. It is the newest series of trains. In addition, the benchmarking capability has been added. Benchmarks are strongly considered for the trial version that will be added in the future. We will try to implement it in the production version for now and if there are no problems, we will include it in the trial version. We will inform you of the differences between the trial version and the full version when the trial version is released.
