Describe the suggestion

I imagine being able to use a radio control independent of Open Computers that you have in your inventory and can use as often and where you want when it is linked to the locomotive.
A suggestion would be an item that you can use in the inventory or put in the shield slot and then open the gui to control the locomotive and then control it with the num pad like standard. (Maybe you can create this gui yourself like with locomotives).
This item (radio remote control) can be linked and unlinked to the locomotive.

Applications of the suggestion

This type of control would improve the fun of the game and make some things possible on servers.

Another disadvantage of open computers is that if you install the Remote Control Card in the tablet to control the locomotive remotely, you can only use it in a certain area. So if you activate it at location A and have a higher distance from the activation location, it will no longer work.
This disadvantage drastically limits the use of the feature via Open Computers.
