My life for the past half year…
Minecart improvements with a 64 m/s max speed. Elytras are disabled on the server since they discourage players from building roads and other infrastructure. After months of experimentation, I've developed a high speed, easy to use, and convenient rail network for my friends.
The biggest hurdle was stoppers. I needed a way to give players time to make decisions such as switching lines or stopping at a station. My original solution was to just use a slopped power rail. However, this breaks at high speeds. Minecarts go so fast they can skip a unpowered rail in one tick. This lead to me using a more complicated piston-based stopped that works at any speed.
