Cart Markers
by CopperMXX
Cart Markers puts a visible warning on minecart setups where two or more carts share the same rail, so players can spot an overload before it turns into a fight.
What it does
When two or more minecarts sit on the same rail, the mod marks that rail with a bright exclamation mark floating above it and draws a red warning ring extending four blocks outward around the carts. The overload is visible from a distance, which matters in a PvP setting where cart-based attacks depend on surprise. Carts added to or removed from a rail update the markers automatically, so the display stays accurate while a setup is being built or dismantled.
The mod is built for PvP awareness: it lets a player who is being approached by a loaded rail see the danger in time to step out of the ring instead of getting carted through blocks. It is a client-side tool, so the server does not need it and players join without installing anything on the server side. Cart Markers is for Fabric and is published for 26.2 only.

A bright exclamation mark appears above each overloaded rail so the setup can be seen at a glance.
Red warning ring
A red ring extends four blocks outward around the carts, marking the area to avoid.
Live updates
Markers change as carts are added or removed, so the display always matches the rail.

A player moving through a PvP area can see a rail loaded with minecarts before entering the red ring.
Building safely
Players constructing their own loaded rails can check the markers while adding carts to confirm the layout.
Who it’s for: Players who spend time in PvP areas where minecart overloads are used, and players who want a visual aid when setting up or dismantling a loaded rail.
