Rails update

Minecarts should be redesigned as old designs looks outdated for modern minecraft, minecarts should be connectable with each other. Speed of minecarts should be increased so that players consider to use it and whole new rail should be added to connect 2 different railway lines. Lastly a minecarts with furnace should be added and it would act as speed boosters so that trains would be added with help of these features and this would help players build, connect places and also transport things from one place to another. Average Speed of minecarts should be increased as it is very slow now. Thanks, hope you'll consider adding such thing in Minecraft
