The after a few hours of analysing real world data, real drivers reports, actual on board live recordings the 0-63mph time ( gear change ) is currently on average varying between 15-30 seconds TOO QUICK to accelerate. From 63mph -90mph it is pretty accurate. Also the braking should be as the new class 377 / 375 brakes are. It is a tad harsh, especially in Step 1. Otherwise it is an incredible model. These things have a reputation for being fairly sluggish now in their old age. Please adjust accordingly.
Thanks for the feedback. The current setup of the train is based on information we could get access to (and GWR were very accommodating and a great partner to work with). We have received very positive feedback about the performance of trains on GWE. Adjusting braking performance is a possibility (though we have no plans to change it), as this only affects when a train needs to begin slowing for a stop. Adjusting acceleration performance is far more difficult as this affects how quickly the train can get from point A to point B. Such a change will have a profound effect on the gameplay and timetables for the route. The change to the train is straight forward enough, but it's the resulting impact that is the issue here. To fix knock-on impacts to the times of services and station stops could end up being a rewrite of the timetable and that would reset progress for everyone who has been driving on Great Western Express for years. Thank you for the investigation and feedback, we will take this onboard going forward, but we cannot action this proposal for the Class 166 on Great Western Express.

Every horizontal line of nodes is an individual train service consisting of station stops and boarding tasks.
