What design pattern to use?

Question

Design patterns

Good afternoon. I'm not very good with patterns. I can’t figure out which one will fit, but I’m almost sure that there is one.
Essence - there is a main class, let it be Depot, and it will have a method for creating a class, conditionally - Tram.
And in the Depot class, there should be information about all "Trams" initialized through this method, so that by calling a certain method in the Depot, it can refer to all Trams (Well, for example, a command for everyone to go to the depot).
How it is better to implement it? Language - PHP. I need to make a competent architecture.

Answer 1

The depot does not create trams. And the "commands" come from the dispatcher.
It is easier to refer to objects in the real world.
you can compose a Prototype to create Trams, Trains (in php this is a clone)
And place it in the Depot - the Pool of objects
Well, then it depends on whether there will be feedback from the Trams with the Depot and with other Trams.
