Hi, in line with current standards on the workshop and all options available in mod.txt files, you should implement these more realistic accelerations stats:
Acceleration 1.2 m/s² (3.9 ft/s²)
Deceleration 1.1 m/s² (3.6ft/s²) (service)
1.4 m/s² (4.6ft/s²) (emergency)
These would help these trains achieve the performance seen in real life, whereas they currently underperform in game. Please use my rebalanced mods as reference for what a high standard on mod.txt should be, including descriptions for car types and as many items filled as possible.
