Railway update!

Railways are not efficient way of transportation. Current railway mechanics were added to the game so long ago that Minecraft had no running mechanic yet. The game evolved but railways - don`t. Railway mechanic should be improved and renovated, here are few ideas how:
1. Maximum speed of minecard should be drastically improved. It is the most obvious proposal;

2. New types of minecards from other materials than iron should be added. It could be golden minecards or copper ones or cards from some another material. These minecards should be better than regular iron minecrads and should include all variations of the minecard;

3. Player should be able to connect few minecads into a train via chains;

4. Minecards should be able to be enchanted. I wrote separate proposal for it (if you interested - check "Enchanted boats and minecards" in my profile). Minecards should be able to ram mobs, survbive the arrow or trident hit and have deeper storage in their chests via enchantments;

5. Some new rail types which will include copper in their craft recipy should be added to the game. Maube powered rails from gold should be boosted and new powered rails from copper should have stats of current powered rails;

6. New types of minecards with some redstone tool inside should be added. For an example - minecards with observer. or dispencer The game already has minecard with hopper, which being actively used in redstone mechanisms.

It is just few brief ideas from me how to improve the railway system
