Hi, here's my problem: I built a world since 2014 in which minecart was the central way of transportation for all points of the map. My biggest city has in it center the central train station and all is built around it to make the easiest way of deplacement by minecarts (I build very big bridges, underwater railway and all kind of infrastructure to support it).

All getting well when the speed was ±16 block / sec. Now it goes to only 8 b/s and all the system getting useless and obsolete.

I dont understand what make my 50 railway so slow that it is now faster to walk beyond each point of the map ... Meanwhile I try boat on ice that allow to go more than 100 block/sec, but this just look unreal for the kind of cities that I'm building.

Can somebody help me to give back to Minecarts their functional speed ? My interest to that game depend of that !

Thank you !
