RailPolish is a Create train and VS2 polish/optimization mod focused on smoother train movement, lower MSPT, better FPS, and fewer crashes.

Added Recent WIP Features:
Chisle & bits Support on trains.
Webdisplays on trains. (bugs may be present still)

It improves carriage interpolation, reduces jitter and rubberbanding, fixes graph rebuild edge cases, improves mounted sync behavior, and adds targeted server-side optimizations to Create train ticking.
Current optimizations include:

up to 99% fewer railway dirty-save calls

100% skipped collision checks for parked trains

75% fewer observer and edge-group update scans

87.5% fewer long-range navigation BFS scans

improved train smoothness under lag with tuned snapshot blending and correction caps

What does this mean for you if this project is successful and working properly:

Smoother Create train motion

Reduced jitter and rubberbanding

Better rider smoothness

Lower server MSPT from train-heavy worlds

Lower CPU overhead from idle or parked trains

Safer handling during graph rebuilds

VS2-compatible sleeping and movement fixes

Client crash prevention for sound concurrency

Issues will be fixed as they are pointed out. The more help the better. LLM Driven project that I am paying for.

Does Not: “guarantee X MSPT” or ect. Dont hang me if its needing more work.

Because actual MSPT also depends on train count, track complexity, and the rest of the modpack.
