This mod + Krastorio 2 + Multiple Unit Train Control = very slow trains.

An acceleration test over a short course (19 rails) using only one locomotive with rocket fuel (approx measurements):
- no mods: 1.6s
- MUTS: 1.6s
- K2: 2.5s
- K2 + MUTC: 2.5s
- K2 + RRTA: 2.5s
- MUTC + RRTA: 5.6s
- RRTA: 5.5s
- K2 + MUTC + RRTA: 8.1s

So:
- K2 slows trains by about a third
- RRTA slows trains by ~70% (very slow relative to stock)
- K2 + RRTA is identical to just K2: bug?
- All three are maybe what would be expected from compounding K2 + RRTA (much too slow)

Happy 2024!
